Hi John,
You can use a property to count the number of iterations and invoke the
next service once all iterations are finished.
For example,
<property name="activitiesCount" expression="count(//result)"
scope="operation"/>
<property name="activitiesIndex" value="0" scope="operation"/>
<iterate expression="//result">
<target>
<sequence>
------
<property name="activitiesIndex"
expression="get-property('operation','activitiesIndex') + 1"
scope="operation"/>
</sequence>
</target>
</iterate>
<filter xpath="get-property('operation',
'activitiesIndex')=get-property('operation','activitiesCount')">
<then>
-----call service---
</then>
</filter>
Thanks,
