Subject Re: using foreach counter
Date Fri, 14 Nov 2008 18:50:21 GMT
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.
-Jon
