maybe returnListener is broken in trinidad 1.0.3

Hi,

if i add a returnListener to my commandButton, which is
defined in a
facet from a table, the returnListener is not called
anymore. Here is a
short example:

<tr:table var="row"
value="#{backing.allRows}">
  <f:facet name="footer">
    <tr:panelButtonBar>
      <tr:commandButton text="Hit me"
partialSubmit="true"
useWindow="true" immediate="true"
action="dialog:openHitMeDialog"
returnListener="#{backing.handleReturn}" />
    </tr:panelButtonBar>
  </f:facet>
  <tr:column>
    <f:facet name="header">
      <af:outputText value="Header 1"
    </f:facet>
    <tr:outputText value="#{row.data}" />
  </tr:column>
</tr:table>

I have tested this scenario with trinidad 1.0.2 and it works
fine. The
difference between these releases is amongst others the jira
issue
TRINIDAD-737. I have removed this changes from my trinidad
1.0.3 source
and started a new build and now the returnListener is called
again.
Is it a problem how i defined the commandButton in my page
or is it a
bug that comes with TRINIDAD-737???

Hope anybody can help me...

Cheers Sven
