I'll post a simple case confirming the problem but I think the stacktrace below, from our complete application, could be more helpfull.
Having a bean method returning a List annotated as @DataModel in a stateless bean is working as before (used before Seam 1.2.1)
@Name("brokenList")
//@Stateful
public class BrokenList implements BrokenListIfa {
public void someOtherMethod(){
}
@DataModel
public List getTestData() {
List l = new ArrayList();
l.add("ONE");
l.add("TWO");
return "testitem";
}
// @Remove @Destroy
public void destroy() {
}
}
The page used to test is something like this:
<h:dataTable value="#{brokenList.testData}" var="d">
<h:column>
<h:outputText value="#{d}" />
</h:column>
</h:dataTable>
When changing the bean to a Stateful bean (as above when enabling commented lines) Seam throws an exception:
javax.faces.FacesException: javax.el.PropertyNotFoundException: /index.xhtml @52,57 value="#{brokenList.testData}": Property 'testData' not found on type org.javassist.tmp.java.lang.Object_$$_javassist_0

Actually when looking at our application's stacktrace whe get some more information (don't really now why they are different):

Looking to Seam's source code it looks like it is calling the setter's method to get the value, as our method doesn't have any parameters. "List" should be the return type, not the argument.
Someone could tell mo more about this? It used to work on Seam 1.2.1
Should I open a JIRA?
