[jboss-user] [JBoss Seam] - pagination control (10.3) missing transaction

[baz]

As gavin  suggested. moved to herehttp://jira.jboss.com/jira/browse/JBSEAM-803
(Could it be, that the @transactional has no effect in my environment: 
Hibernate running in microcontainer on tomcat 
Using the configuration from the Docu chapter 19.5)
I do have implemented the pagination control (Chapter 10.3 from the docu. 
This piece of code does not function: 
<s:link view="/listUser.xhtml" rendered="#{myUserList.nextExists}" value=" last "> 
     <f:param name="firstResult" value="#{myUserList.lastFirstResult}"/> 
 </s:link> 
When rendering the page an exception is thrown: 
2:13:28,734 DEBUG org.jboss.seam.core.Events: Processing event:org.jboss.seam.postSetVariable.myUserList 
12:13:28,750 DEBUG org.jboss.util.NestedThrowable: org.jboss.util.NestedThrowable.parentTraceEnabled=true

After removing this piece of code the pagination works for first,last and next.
I have debugged the app. 
getLastFirstResult is called which calls getResultCount form HibernateEntityQuery 
The query gets generated 
but Integer) query.uniqueResult(); 
raises the excepton about the missing transaction. 

Any ideas what went wrong?
Ciao,
Carsten
