[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3742) pages.xsd cannot use static navigation

pages.xsd cannot use static navigation
--------------------------------------
Key: JBSEAM-3742
URL: https://jira.jboss.org/jira/browse/JBSEAM-3742
Project: Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.1.0.SP1
Reporter: Gonzalez Adrian
pages-2.1.xsd is too restrictive, I cannot write anymore :
<navigation from-action="goBack">
>From pages.xsd definition, 'from-action' value must always be an El expression (so called 'dynamic navigation').
This shouldn't be the case, web should be able to use static navigation.
Here's the pages-2.1.xsd showing the restriction :
<xs:simpleType name="view-id">
<xs:restriction base="xs:string">
<xs:pattern value="(/.*)|\*"/>
</xs:restriction>
</xs:simpleType>
<xs:attributeGroup name="attlist.navigation">
<xs:attribute name="from-action" type="pages:method-expression" />
<xs:attribute name="evaluate" type="pages:method-expression" />
</xs:attributeGroup>

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3729) Recognize HotDeployFilter as a configurable filter in web.xsd

Recognize HotDeployFilter as a configurable filter in web.xsd
-------------------------------------------------------------
Key: JBSEAM-3729
URL: https://jira.jboss.org/jira/browse/JBSEAM-3729
Project: Seam
Issue Type: Feature Request
Components: Hot Deploy
Affects Versions: 2.1.0.SP1
Reporter: Dan Allen
Fix For: 2.1.1.CR2
It's absolutely critical that the HotDeployFilter only be applied to JSF requests or else the scanning that it does occurs for every related requested by the page. However, currently none of the XML schemas for the component descriptor recognize this filter as a configurable element. Here is how it has to be configured now:
<component name="org.jboss.seam.debug.hotDeployFilter">
<property name="urlPattern">*.seam</property>
</component>
I would like to do one of two things.
#1
Change the component name from org.jboss.seam.debug.hotDeployFilter to org.jboss.seam.web.hotDeployFilter (but still keep it in jboss-seam-debug.jar), then add the hot-deploy-filter element to web.xsd. We would get this:
<web:hot-deploy-filter url-pattern="*.seam"/>
We could even consider moving this filter into jboss-seam.jar because honestly it is so lightweight and really has everything to do with the core and is already controlled by the debug mode flag in Seam.
#2
Keep the component name as is and introduce a new namespace http://jboss.org/products/seam/debug and a corresponding package-info.java and debug.xsd. Then add the hot-deploy-filter to debug.xsd. We would get this:
<debug:hot-deploy-filter url-pattern="*.seam"/>
I really hate solution #2. The only redeeming quality is that it doesn't break applications that might rely on this component name. But then again, it would only affect debug mode, not production apps.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3612) examples should demonstrate obtaining entity manager factory from JNDI via persistence unit reference

examples should demonstrate obtaining entity manager factory from JNDI via persistence unit reference
-----------------------------------------------------------------------------------------------------
Key: JBSEAM-3612
URL: https://jira.jboss.org/jira/browse/JBSEAM-3612
Project: Seam
Issue Type: Feature Request
Components: Examples
Affects Versions: 2.1.0.GA
Reporter: Dan Allen
Priority: Minor
Fix For: 2.1.1.CR1
For any example that is deploying to a standard Java EE 5 environment (for instance the jpa example deploying to GlassFish or JBoss AS 5), the entity manager factory should be obtained through JNDI through a persistence unit reference.
5.3.1 of JPA spec:
"Within a Java EE environment, an entity manager factory may be injected using the Persistence-Unit annotation or obtained through JNDI lookup."
It would first need to be declared in web.xml:
<persistence-unit-ref>
<persistence-unit-ref-name>bookingDatabase/emf</persistence-unit-ref-name>
<persistence-unit-name>bookingDatabase</persistence-unit-name>
</persistence-unit-ref>
Then the components.xml would look like this:
<persistence:managed-persistence-context name="entityManager"
auto-create="true"
persistence-unit-jndi-name="java:comp/env/bookingDatabase/emf" />
The reason we should do this is to advocate the Java EE standard approach.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3643) "Group by" paging failed

"Group by" paging failed
------------------------
Key: JBSEAM-3643
URL: https://jira.jboss.org/jira/browse/JBSEAM-3643
Project: Seam
Issue Type: Bug
Components: Framework
Affects Versions: 2.1.0.GA
Environment: JBoss 4.2.3GA, Seam 2.1.0GA,JDK 1.5.0_16
Reporter: Kenneth Zhang
GroupBy is a new function at seam 2.1.0GA, but it cannot work with paging.
This is the test code:
@Name("bookStat")
public class BookStat extends EntityQuery<Book> {
private static final String EJBQL = "select name, count(*) from Book book";
(snip)
public BookStat() {
setEjbql(EJBQL);
setRestrictionExpressionStrings(Arrays.asList(RESTRICTIONS));
setMaxResults(3);
setGroupBy("name");
}
(snip)
}
There is the error log:
13:05:09,578 INFO [STDOUT] Hibernate:
