Can't leave node ... without leaving transition

[victorl]

Hi All,

I have a very simple process like this:

process-definition xmlns="" name="process"
start-state name="init process"
transition to="documentation control" name="trNo1"
node name="documentation control"

And the following code:

definition = graphSession.findLatestProcessDefinition("process");
processInstance = new ProcessInstance(definition );
token = processInstance.getRootToken();
token.signal();

But when the signal is executed from the start state to documentation control node the following exception is thrown:

org.jbpm.JbpmException: can't leave node 'Node(documentacion control)' without leaving transition
at org.jbpm.graph.def.Node.leave(Node.java:365)
at org.jbpm.graph.def.Node.leave(Node.java:347)
at org.jbpm.graph.def.Node.execute(Node.java:339)
at org.jbpm.graph.def.Node.enter(Node.java:316)
...
...

I don't know because it is happening.

Any help will be very appreciated
Best Regards,

Victor

posting within code tags also helps as does making a real unit test

I suggest that before you signal() that you find out from the token which Node it's sitting at...

Thank you very much Ronald and pojomonkey for the responses.

By means this instruction
System.out.println(token.getNode().getName());

I can see that process is in the correct node: it is 'init process'

Thanks once again

Just realised - the 'raw' Node type does NOT have a wait state and will hence try to leave() as soon as gets there.

And it doesn't have a leaving transition, so the error is correct.

Hi pojomonkey,

I resolved the problem making the documentation control node a state node type.

Thank you very much once again.
