I'm having strange error while using sub proces and leaveNode in actions. Here is
simplified example.
Main process definition:
| <?xml version="1.0" encoding="UTF-8"?>
| <process-definition name="testParent">
| <start-state name="start">
| <transition to="state"/>
| </start-state>
| <state name="state">
| <event type="node-enter">
| <action class="org.mule.providers.bpm.jbpm.actions.Continue"/>
| </event>
| <transition to="subProcess"/>
| </state>
| <process-state name="subProcess">
| <sub-process name="testSubProcess"/>
| <transition to="end"/>
| </process-state>
| <end-state name="end"/>
| </process-definition>
|
Sub process definition:
| <?xml version="1.0" encoding="UTF-8"?>
| <process-definition name="testSubProcess">
| <start-state name="start">
| <transition to="testState"/>
| </start-state>
| <state name="testState">
| <event type="node-enter">
| <action class="org.mule.providers.bpm.jbpm.actions.Continue"/>
| </event>
| <transition to="end"/>
| </state>
| <end-state name="end"/>
| </process-definition>
|
org.mule.providers.bpm.jbpm.actions.Continue implementation:
| public void execute(ExecutionContext executionContext) throws Exception
| {
| executionContext.leaveNode();
| }
|
When executing this process, engine throws an error:
| org.jbpm.JbpmException: can't continue execution on locked tokens. signalling the
same token that executes an action is not allowed

Is this a bug in JBpm or I'm doing something wrong?
