----------------------------------------
@Vineet i think that the problem is still present and the bug must be reopened, because
it's not only related to the UI (that not showing the field like pointed in
https://issues.jboss.org/browse/FORGE-870) but, with preloaded data in the database or
insert data with PK set to auto increment, i see the entries but if i click it for the
detail i have an error like this in console : Provided id of the wrong type for class
org.forgetest.model.GeoCities. Expected: class java.lang.String, got class
java.lang.Long.
Now i have tried to add an id column (BIGINT) to all table and make it PK as a
workaround..it works
I can add and view data...but i found other three bug.
One is https://issues.jboss.org/browse/FORGE-870, i have it for example in all
Many-to-Many table.
Second is that : if there is a column which reference a PK of the another table the GUI
show a dropdown menu( with "non-human meaning" value ). after setting this value
and saving, all seems ok, but when i want to modify something for this record the GUI not
show me the value that was setted. it's not much clear, i know..
Third (but i think its related to Hibernate) : i have two table with a 1:1 identifying
relatioship, and so they have the same PK, when generate entities have a method for the
class like
public void newStrCustomServices()
{ this.getStrCustomServices = new StrCustomServices(); }
but there isn't any attribute in the class like "getStrCustomServices", to
fix i need to change it in "strCustomServices", and so the UI work but with the
previous first bug.
Forge scaffold faces creates view beans with Id always Long against
user-generated Entities
-------------------------------------------------------------------------------------------
Key: FORGE-572
URL: https://issues.jboss.org/browse/FORGE-572
Project: Forge
Issue Type: Bug
Components: Scaffold
Affects Versions: 1.0.2.Final
Environment: JBoss Developer Studio 5 Beta 2, Embedded Forge 1.0.2.Final
Reporter: Will Dinyes
Assignee: Vineet Reynolds
Priority: Minor
Labels: starter
Fix For: 1.2.4.Final
When running:
scaffold from-entity ~.domain.* --overwrite
The generated view Bean will always use an id field as a long, even if the entity uses a
different type for the @Id. For instance, this code, in an Entity class called
ValMealtype:
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(unique=true, nullable=false, length=20)
private String meal;
Generates, in ValMealtypeBean:
private Long id;
<-- associated gettters and setters -->
And, later in the class:
return ValMealtypeBean.this.entityManager.find(ValMealtype.class, Long.valueOf(value));
That line in particular doesn't work at all, of course, since a Long can't be
parsed out of a non-numeric String. I suppose I could name my meals with hex digits . . .
CAFE . . . BEEF . . . but sadly, Chicken isn't going to fly.
Basically, scaffold probably needs to look at the type of @Id in the entity and use that
to set the id field type in the generated bean.
As this is reported against a non-current release, I understand it may be fixed already.
In this case, a new Beta of JBDS 5 is probably in order, as that's where I'm
seeing this issue.
