I am also looking for an answer to this question. Here's another example
that does not work..
<bpws:forEach counterName="Counter" name="ForEach" parallel="no">
<bpws:startCounterValue expressionLanguage="...xpath1.0">
<![CDATA[1]]>
</bpws:startCounterValue>
<bpws:finalCounterValue expressionLanguage="...xpath1.0">
<![CDATA[10]]>
</bpws:finalCounterValue>
<bpws:scope>
<bpws:if name="If">
<!-- We never get here -->
<bpws:empty name="NeverGetsHere"/>
<bpws:condition expressionLanguage="...xpath1.0">
<![CDATA[$Counter > 5]]>
</bpws:condition>
</bpws:if>
</bpws:scope>
</bpws:forEach>
Can anyone else reproduce this?
Thanks.
