seam-gen and mutiple foreign keys
---------------------------------
Key: JBSEAM-994
URL: http://jira.jboss.com/jira/browse/JBSEAM-994
Project: JBoss Seam
Issue Type: Bug
Components: Tools
Affects Versions: 1.2.0.GA
Environment: JBoss-4.0.5
Reporter: Niels Hoogeveen
I have generated a project with seam-gen based on generate-entities. All works fine,
except for the generation of the home interfaces. In one of my tables I have two foreign
keys to the same table. In the home interface two references are created to the
appropriate object, but with the same name (which of course doesn't compile).
Here is a simplified example:
Table 1
Code:
CREATE TABLE test
(
id int4 NOT NULL DEFAULT nextval('test_id_seq'::regclass),
name varchar,
id_test2_1 int4,
id_test2_2 int4,
CONSTRAINT test_pkey PRIMARY KEY (id),
CONSTRAINT test_id_test2_1_fkey FOREIGN KEY (id_test2_1)
REFERENCES test2 (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION,
CONSTRAINT test_id_test2_2_fkey FOREIGN KEY (id_test2_2)
REFERENCES test2 (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)
Table2
Code:
CREATE TABLE test2
(
id int4 NOT NULL DEFAULT nextval('test2_id_seq'::regclass),
name varchar,
CONSTRAINT test2_pkey PRIMARY KEY (id)
)
First Entity
Code:
@Entity
@Table(name = "test", schema = "public")
public class Test implements java.io.Serializable {
private int id;
private Test2 test2ByIdTest22;
private Test2 test2ByIdTest21;
private String name;
public Test() {
}
public Test(int id) {
this.id = id;
}
public Test(int id, Test2 test2ByIdTest22, Test2 test2ByIdTest21,
String name) {
this.id = id;
this.test2ByIdTest22 = test2ByIdTest22;
this.test2ByIdTest21 = test2ByIdTest21;
this.name = name;
}
@Id
@Column(name = "id", unique = true, nullable = false)
@NotNull
public int getId() {

}
public void setId(int id) {

No, this patch is not a correct solution, in fact I don't see any easy way to arrive
at a correct solution - this is a super-difficult one to solve by code generation, it
needs human-written code.

-------------------------------------
Yes it won't be easy but it's possible to generate code for such a case.
I worked a little on this issue some time ago. I stopped as I was stuck with the tricky
issue of data to keep between pages. To resume, I'm waiting the possibility to use
parameters with valueexpression. I undestood it will be available soon.

[ http://jira.jboss.com/jira/browse/JBSEAM-994?page=comments#action_12364055 ]
Pierre Raoul commented on JBSEAM-994:
-------------------------------------
Herewith a patch which addresses two issues:
- to deal with an entity which has two or more attributes with the same entity as type,
i.e. the above multiple foreign keys issue
- to be able to come back on the calling page, for example after adding/editing an entity
attribute or showing detail of an item in a list attribute.
It works with jpaconfiguration (see JBSEAM 843). There is a new target (seam generate-ui)
to create the ui from entities.
It can be run as often as wished.
I only tested it from entity pojos and for ear projects in dev mode.
I didn't try reverse engineering from data bases.
About the second issue (links between crud pages): I tested only one level of deepth
between linked entities. I don't know if it will work fine with entity attributes in
cascade.
The patch is generated against today cvs.
I used some new materials:
- javassist for hibernate tools
- xmltask to merge fine-grained configuration files
- tomahawk as I use "t:buffer" tag to manage with complex expression
in xhtml files
(yes I know, it's quite a heavy tool just for that, but it's the only
one I found ready to be used...)
tomahawk needs commons-fileupload.jar
- log4j to avoid some error messages from hibernate during "generated-ui"
Two secondary issues:
- I didn't find how to avoid putting "hibernate.dialect"
in persistence-dev.xml
- With the current "seam.bat" under Windows, there is no way to work with
the right hibernate annotations and entitymanager libraries.
Ant is called with {seam_home}/lib in both "ant.home" and
"ant.library.dir".
As:
* hibernate-all.jar is in {seam_home}/lib,
* and HAN and HEM are in hibernate-all.jar,
the libraries in {seam_home}/hibernate/lib are never loaded.
But the HAN and HEM classes in hibernate-all.jar are too old:
version 3.2.0.CR3 or above is needed.
As turnaround, I use a new directory {seam_home}/ant/lib with
only ant.jar and I put it in "ant.home" and "ant.library.dir"
during "generated-ui".
seam-gen and mutiple foreign keys

I have generated a project with seam-gen based on generate-entities. All works fine,
except for the generation of the home interfaces. In one of my tables I have two foreign
keys to the same table. In the home interface two references are created to the
appropriate object, but with the same name (which of course doesn't compile).
Here is a simplified example:
Table 1
Code:
CREATE TABLE test
(
id int4 NOT NULL DEFAULT nextval('test_id_seq'::regclass),
name varchar,
id_test2_1 int4,
id_test2_2 int4,

ON UPDATE NO ACTION ON DELETE NO ACTION,
CONSTRAINT test_id_test2_2_fkey FOREIGN KEY (id_test2_2)

ON UPDATE NO ACTION ON DELETE NO ACTION
)

test2Home.

If you want to make more than one change, you must submit multiple patches under separate
JIRA issues. I never, ever, ever simply commit massive patches full of unrelated changes.
FYI, I will probably reject most of your changes. (For example, no way in hell are we
going to get a dependency to Tomahawk!)

Pierre Raoul commented on JBSEAM-994:
-------------------------------------
I never hoped the patch would be accepted as it is. I'm ready to rework it (them!). I
just want some advice before I resume.
About "unrelated changes", is it ok with this list:
- seam-gen/resources/messages_en.properties (new Jira issue): add missing equal signs
- seam-gen/view.*.ftl (new Jira issue): close with "/>" the
"assign" tags without body and the "include" ones. Then the
freemarker editor can checked if all the freemarker tags are balanced.
- seam-gen/view/params.xml.ftl (new JIRA issue): "assign" defines always a
global variable, so "parentPojo" backup is useless. In fact it works as it is
only because there is no other "assign" after the include of params.xml.ftl in
the file. Patch: define a macro, then even with instructions after the include, it will
work.
- Generate application from existing entities (JBSEAM-843): no news since the 30/03/07
(patch from Max Anderson about jpaconfiguration in seam-gen/build.xml and patches from me
about tests to detect java class in freemarker files)
- Seam-gen and multiple foreign keys (JBSEAM-994): deal here only with the ManyToOne
associations.
- In a entity, two or more attributes with collection of the same entity as type (new Jira
issue): same kind of issue than above but with OneToMany associations.
- Backward link between pages of different entities (new Jira issue): atm,
save/select/done/cancel commands on a page always return to default page i.e. either list
or view page of the same entity. It should be possible to return to the calling page.
About tomahawk: I was quite aware you won't accepted it. There are three options
here:
- use only EL expressions: should be possible here, even if ugly
- add specific functions to EntityHome.java and EntityList.java: should be possible now
that paramaters are ok in value expressions
- clone t:buffer
I have no real preference...
About other issues with my patch (at least other than unrelated changes), can you be more
specific?

I have generated a project with seam-gen based on generate-entities. All works fine,

----------------------------------
Gavin, I came across this problem too while using seam-gen. I wonder if we can just get it
so that the generated code passes basic compilation. Some way want the page to work
correctly, but most will probably just not want to have to deal with the compilation error
before even getting started with the project. Can we accomplish just that?

Bruce Link commented on JBSEAM-994:
-----------------------------------
Should indicate that it affects 2.1.0.SP1 not just 1.2.0.GA.
Would be nice if it were scheduled to be fixed. Logic error is that it uses the table
name of the referenced table instead of the field name holding the foreign key. For
example, in a table REVIEW. there are two fields, employee and reviewer, referencing a
STUDENT table. In the entity Review, two fields are generated (improvement from a year
ago): studentByEmployer and studentByReviewer.
ReviewHome, however, creates two fields:
StudentHome studentHome;
StudentHome studentHome;
which of course won't compile.
I am not sure the wiring logic would work once you fix that issue?
Generated code:
public void wire() {
getInstance();
Student studentByEmployee = studentHome.getDefinedInstance();
if (studentByEmployee != null) {
getInstance().setStudentByEmployee(studentByEmployee);
}
Student studentByReviewer = studentHome.getDefinedInstance();
if (studentByReviewer != null) {
getInstance().setStudentByReviewer(studentByReviewer);
}

I have generated a project with seam-gen based on generate-entities. All works fine,
except for the generation of the home interfaces. In one of my tables I have two foreign
keys to the same table. In the home interface two references are created to the
appropriate object, but with the same name (which of course doesn't compile).
Here is a simplified example:

Julien Kronegg commented on JBSEAM-994:
---------------------------------------
In Seam 2.1.1.GA, the major problem is that every time the "seam-gen
generate-entities" is done, all EntityHomes are compiled. So that you need to correct
the files each time before calling the generate-entities... and they are re-generated with
duplicated EntityHome, so its very painful.
The workaround is to change the ${PROJECT_NAME}/build.xml file by removing the <javac
...> tag from its parent target "compileactions". This is a "brute
force" approach, but very convenient. ;-)
BTW, it would be very nice to solve this issue (although I do not think that the provided
patches really works, e.g. when entity homes are in a different package, see
https://jira.jboss.org/jira/browse/JBSEAM-3278).

Rodrigo L�³pez Guzm�¡n commented on JBSEAM-994:
---------------------------------------------------
I left only one instance of the home object and tried the following changes in TestHome
above:
public void wire() {
Test2 test2ByIdTest22 =
test2Home.getInstance(getInstance().getTest2ByIdTest22().getId());
if (test2ByIdTest22 != null) {
getInstance().setTest2ByIdTest22(test2ByIdTest22);
}
Test2 test2ByIdTest21 =
test2Home.getInstance(getInstance().getTest2ByIdTest22().getId());
if (test2ByIdTest21 != null) {
getInstance().setTest2ByIdTest21(test2ByIdTest21);
}
}
and added the following on TestHome2:
public Estado getInstance(int id) {
setId(id); //I set the id, so next getInstance brings the
correct instance
return getInstance(); //this returns an instance depending on getId()
}
This worked fine for edition, since it shows different Test2 instances (before this, it
always showed them the same). But it breaks when creating a new TestHome.
Is it possible to have a simple solution with this idea? I haven't been able to solve
this problem at all; one thing is to solve it in seam-gen, but I don't even know how
to solve it "by hand".

I haven't been able to solve this problem at all; one thing is to solve it in
seam-gen, but I don't even know how to solve it "by hand".
[quote]
The main issue is not in the java classes but in the wiring around them, i.e. the
page.xml, edit.xhtml... files. Even if it's no more synchronized with the current seam
code, you can get a good idea with the "doublon" patch herewith. The patch
updates all the wiring during each generate cycle.
And yes, seam-gen manages only one package, so the patch works with one package but
doesn't do more...

I have generated a project with seam-gen based on generate-entities. All works fine,

----------------------------------
I think that attempting to solve this issue makes the generated code too complicated,
defeating the purpose of the who exercise. There is no way you would want to use the
generated UI to establish such a relationship anyway. It is much better to put some select
boxes on the page so the user can just see options. I uploaded a patch that simply allows
the Java class to compile so you can get on with your work.

Home interface of first entity. Here we have two Test2Home references, both with the name
test2Home.
Code:
@Name("testHome")
public class TestHome extends EntityHome<Test> {

@In(create = true)
Test2Home test2Home;
public void setTestId(Integer id) {
setId(id);
}
public Integer getTestId() {

}
@Override
protected Test createInstance() {
Test test = new Test();
return test;
}
public void wire() {
Test2 test2ByIdTest22 = test2Home.getDefinedInstance();
if (test2ByIdTest22 != null) {
getInstance().setTest2ByIdTest22(test2ByIdTest22);
}
Test2 test2ByIdTest21 = test2Home.getDefinedInstance();
if (test2ByIdTest21 != null) {

seam-gen and mutiple foreign keys
---------------------------------
Key: JBSEAM-994
URL: https://jira.jboss.org/jira/browse/JBSEAM-994
Project: Seam
Issue Type: Bug
Components: Tools
Affects Versions: 1.2.0.GA
Environment: JBoss-4.0.5
Reporter: Niels Hoogeveen
Assignee: Dan Allen
Attachments: doublon.patch, doublon.zip, doublon2.patch,
EntityHome.java.ftl.patch, JBSEAM-994-2.2.x.patch, seam-gen.diff, seam-gen.zip
I have generated a project with seam-gen based on generate-entities. All works fine,
except for the generation of the home interfaces. In one of my tables I have two foreign
keys to the same table. In the home interface two references are created to the
appropriate object, but with the same name (which of course doesn't compile).
Here is a simplified example:
Table 1
Code:
CREATE TABLE test
(
id int4 NOT NULL DEFAULT nextval('test_id_seq'::regclass),
name varchar,
id_test2_1 int4,
id_test2_2 int4,
CONSTRAINT test_pkey PRIMARY KEY (id),
CONSTRAINT test_id_test2_1_fkey FOREIGN KEY (id_test2_1)
REFERENCES test2 (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION,
CONSTRAINT test_id_test2_2_fkey FOREIGN KEY (id_test2_2)
REFERENCES test2 (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)
Table2
Code:
CREATE TABLE test2
(
id int4 NOT NULL DEFAULT nextval('test2_id_seq'::regclass),
name varchar,
CONSTRAINT test2_pkey PRIMARY KEY (id)
)
First Entity
Code:
@Entity
@Table(name = "test", schema = "public")
public class Test implements java.io.Serializable {
private int id;
private Test2 test2ByIdTest22;
private Test2 test2ByIdTest21;
private String name;
public Test() {
}
public Test(int id) {
this.id = id;
}
public Test(int id, Test2 test2ByIdTest22, Test2 test2ByIdTest21,
String name) {
this.id = id;
this.test2ByIdTest22 = test2ByIdTest22;
this.test2ByIdTest21 = test2ByIdTest21;
this.name = name;
}
@Id
@Column(name = "id", unique = true, nullable = false)
@NotNull
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "id_test2_2")
public Test2 getTest2ByIdTest22() {
return this.test2ByIdTest22;
}
public void setTest2ByIdTest22(Test2 test2ByIdTest22) {
this.test2ByIdTest22 = test2ByIdTest22;
}
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "id_test2_1")
public Test2 getTest2ByIdTest21() {
return this.test2ByIdTest21;
}
public void setTest2ByIdTest21(Test2 test2ByIdTest21) {
this.test2ByIdTest21 = test2ByIdTest21;
}
@Column(name = "name", length = 0)
@Length(max = 0)
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
}
second entity
Code:
@Entity
@Table(name = "test2", schema = "public")
public class Test2 implements java.io.Serializable {
private int id;
private String name;
private Set<Test> testsForIdTest21 = new HashSet<Test>(0);
private Set<Test> testsForIdTest22 = new HashSet<Test>(0);
public Test2() {
}
public Test2(int id) {
this.id = id;
}
public Test2(int id, String name, Set<Test> testsForIdTest21,
Set<Test> testsForIdTest22) {
this.id = id;
this.name = name;
this.testsForIdTest21 = testsForIdTest21;
this.testsForIdTest22 = testsForIdTest22;
}
@Id
@Column(name = "id", unique = true, nullable = false)
@NotNull
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
@Column(name = "name", length = 0)
@Length(max = 0)
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy =
"test2ByIdTest21")
public Set<Test> getTestsForIdTest21() {
return this.testsForIdTest21;
}
public void setTestsForIdTest21(Set<Test> testsForIdTest21) {
this.testsForIdTest21 = testsForIdTest21;
}
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy =
"test2ByIdTest22")
public Set<Test> getTestsForIdTest22() {
return this.testsForIdTest22;
}
public void setTestsForIdTest22(Set<Test> testsForIdTest22) {
this.testsForIdTest22 = testsForIdTest22;
}
}

Test2Home test2Home;

}
public Integer getTestId() {
return (Integer) getId();
}
@Override
protected Test createInstance() {
Test test = new Test();
return test;
}
public void wire() {
Test2 test2ByIdTest22 = test2Home.getDefinedInstance();
if (test2ByIdTest22 != null) {

}
Test2 test2ByIdTest21 = test2Home.getDefinedInstance();
if (test2ByIdTest21 != null) {
getInstance().setTest2ByIdTest21(test2ByIdTest21);
}
}
public boolean isWired() {
return true;
}
public Test getDefinedInstance() {
return isIdDefined() ? getInstance() : null;
}
}
BTW. I used the latest seam version from CVS.
