How can I access a process instance in jPDL, eg when I want to pass the id or key of the processInstance to a java activity?
<java class="...classname..." method="execute" name="DoSomeJava">
<arg>
<object expr="#{??????}"/>
</arg>
<transition to="Next Step"/>
</java>
What must ????? be to send the processInstanceId/Key to the java class?
I can't seem to find a reference to see which process attributes are available and how. Might also be handy to at times send activity name to generic java classes, etc.
