I'm adapting the seam-messages example for my own application. I am NOT using
a stateful bean since my message list has no need to be selectable - I'm simply
trying to dump my message list to HTML in a datatable.
The only differences between the example and my app is that I uses a stateless
bean and a non-extended EM. When I use am extended persistence context I get
this error:

| javax.faces.el.EvaluationException: Cannot get value for expression 'Num
messages: #{mobileGatewayRequestList.rowCount}'
|
|
Because of this:
|
| public class ExtendedPersistenceContextInjector implements Injector,
PojoInjector
| {
| // bits skipped
| public void inject(BeanContext beanContext, Object instance)
| {
| StatefulBeanContext ctx = (StatefulBeanContext)beanContext;
| EntityManager pc =
ctx.getExtendedPersistenceContext(factory.getKernelName());
| if (pc == null)
| {
| pc = factory.createEntityManager();
| ctx.addExtendedPersistenceContext(factory.getKernelName(), pc);
| }
| }
|
| }
|
Am I miss understanding something?
When I am using a non-extened EM I get bizzare results, my table of results
does not render due to
| <h:outputText value="No messages to display"
rendered="#{mobileGatewayRequestList.rowCount==0}"/>
|
BUT the following does not render either:
| <h:outputText value="Num messages: #{mobileGatewayRequestList.rowCount}"/>
|
Which makes no sense,
