Hi all
I'm trying to create an iterated subprocess (basically, pattern 14
http://www.workflowpatterns.com/patterns/control/multiple_instance/wcp14.php ). I found http://wiki.jboss.org/wiki/attach?page=ForEachForkActionHandler%2FForEachForkActionHandler.java
which provides the ability to, on a node, specify that all leaving transitions are looped 'for each' item in a list. This works as expected with a simple node that as some script. i havent checked how it fares for task-nodes (which, invariably) is what i want.
What im trying to do is spawn a sub process for each item in the list.
I have the leaving transition wired to a process-state node which and that fails as the ForEachActionHandler.java gets to calling leave().
Simple nodes: fine
Process-state nodes: not so good.
Below are my 2 process definitions.
|
| <process-definition name="foreach2">
|
| <start-state name="start">
| <transition to="foreachfork" />
| </start-state>
|
| <node name="foreachfork">
| <action class="com.my.test.workflow.util.ForEachActionHandler"
| config-type="bean">
| <listVariable>assets</listVariable>
| <as>asset</as>
| </action>
| <transition name="foreach2_sub" to="foreach2_sub"/>
| </node>
|
| <process-state name="foreach2_sub">
| <sub-process name="foreach2_sub" />
| <variable name="asset" access="read,write" mapped-name="asset" />
| <transition to="joinforeach" />
| </process-state>
|
| <join name="joinforeach">
| <transition to="end"/>
| </join>
|
| <end-state name="end"/>
|
|
| </process-definition>
|
| <process-definition name="foreach2_sub">
| <start-state name="start">
| <transition to="one" />
| </start-state>
|
| <node name="one">
| <script>
| System.out.println("foreach2_sub one: " + asset);
| </script>
| <transition to="two"/>
| </node>
| <node name="two">
| <script>
| System.out.println("foreach2_sub two: " + asset);
| </script>
| <transition to="end"/>
| </node>
|
| <end-state name="end"/>
| </process-definition>

Thank you for any help,
