Problem with Tomcat

Hi all,

When I use openjpa with Tomcat 6.0.13 (without -javaagent option), i 
experience strange behavior.

I have set of entities com.test.MyEntity, that I iterate using JSF 
h:dataTable tags.

<h:dataTable value="#{myBean.myEntityCollection}" var="row">
     <h:column>
         <h:outputText value="#{row}"/><br/>
         <h:outputText value="#{row.class.name}"/>
     <h:column>
</h:dataTable>

Interesting, two outputText tags give different results:

org.apache.openjpa.enhance.com$test$MyEntity$pcsubclass@de04cd
org.apache.openjpa.util.java$util$HashSet$proxy

Can anyone explain this? It causes me problems because when I try to 
access property in MyEntity,

         <h:outputText value="#{row.myProperty}"/><br/>

exception is thrown:

org.apache.jasper.el.JspPropertyNotFoundException: /page.jsp(115,14) 
'#{row.myProperty}' Property 'myProperty' not found on type 
org.apache.openjpa.util.java$util$HashSet$proxy


Regards,
Ognjen

Oh, sorry, my mistake. dataTable can't iterate through set. Not an 
openjpa issue.
