s:graphicImage throws NullPointerException GraphicImageResource.doWork when el expression for value is null
-------------------------------------------------------------------------------------------------------------
Key: JBSEAM-3011
URL: http://jira.jboss.com/jira/browse/JBSEAM-3011
Project: Seam
Issue Type: Bug
Affects Versions: 2.0.1.GA
Environment: all
Reporter: Coral Featherstone
An exception is thrown when s:graphicImage value is given an EL expression, part or all of which is null.
.
We are using s:graphicImage in a rich:modalPanel as the edit part of the crud and it relies on the selected row of a rich:datatable to get the image bytes. When no row is selected the following stack is thrown.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2983) Unknown Entity when persisting seam managed JPA entity
by Guillaume Jeudy (JIRA)
Unknown Entity when persisting seam managed JPA entity
------------------------------------------------------
Key: JBSEAM-2983
URL: http://jira.jboss.com/jira/browse/JBSEAM-2983
Project: Seam
Issue Type: Bug
Affects Versions: 2.0.1.GA
Reporter: Guillaume Jeudy
Priority: Minor
Caused by: java.lang.IllegalArgumentException: Unknown entity: com.archinsurance.rdm.entity.packages.impl.RefReleasePackageImpl_$$_javassist_4
at org.hibernate.ejb.AbstractEntityManagerImpl.persist(AbstractEntityManagerImpl.java:215)
when attempting to persist a seam managed JPA entity. Seam instantiates a javassist proxy and this is what the user app is trying to persist.
The exception is not thrown when the entity is marked with @Entity annotation, if it is mapped with XML hibernate mapping definition it will fail with the above exception.
Implement a consistent behavior to handle the seam managed JPA entity usecase regardless of the mapping technique being used. As recommended by Pete Muir this use case should not be utilized.
Suggested behavior should be to throw a more explicit exception on startup whenever this invalid usecase is detected.
More details in the below forum thread:

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3118) Unclear ItemValidator example in reference (31.2)

Unclear ItemValidator example in reference (31.2)
-------------------------------------------------
Key: JBSEAM-3118
URL: http://jira.jboss.com/jira/browse/JBSEAM-3118
Project: Seam
Issue Type: Bug
Components: Documentation Issues
Affects Versions: 2.1.0.A1
Reporter: Richard Richter
In section 31.2 of Seam reference (2.1 version) there is an example which is not very clear:
@Name("itemValidator")
@BypassInterceptors
@Validator
public class ItemValidator implements Validator {
public void validate(FacesContext context, UIComponent cmp, Object value)
throws ValidatorException {
ItemController ItemController = (ItemController) Component.getInstance("itemController");
return itemController.validate(value);
}
}
First thing is that if you accept one import for Validator, the other usage of that type is broken - there are both Hibernate Validator annotation and JSF Validator interface used (I'd use FQN for this one probably). Other thing is that there is return of something for void method. Example is rather confusing as it is now.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3137) Numberguess example throws NoClassDefFoundError: org/richfaces/webapp/taglib/UIComponentELTagBase

Numberguess example throws NoClassDefFoundError: org/richfaces/webapp/taglib/UIComponentELTagBase
-------------------------------------------------------------------------------------------------
Key: JBSEAM-3137
URL: http://jira.jboss.com/jira/browse/JBSEAM-3137
Project: Seam
Issue Type: Bug
Components: Examples
Affects Versions: 2.1.0.BETA1
Reporter: Stan Silvert
If I run the trunk version of numberguess, I get:
javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/richfaces/webapp/taglib/UIComponentELTagBase
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:273)
javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
I'm looking through the code and I noticed that org.jboss.seam.ui.util.cdk.UIComponentTagBase extends the RichFaces UIComponentELTagBase. I assume that is the problem? I assume you don't want Seam to be dependent on RichFaces?
Also, Seam's UIComponentTagBase is marked as @deprecated.
So I'm not sure how to proceed. I could add the RichFaces jar to numberguess, but that's probably not the correct fix.
