Hello,
I can sucessfully invoke REST api for starting service, however invoking /rs/process/tokens/<process instance id>/transition?signal=<signal name> does not send signals to process engine.
If I run process locally (in eclipse):
#
kcontext.getKnowledgeRuntime().signalEvent( eventType, data, kcontext.getProcessInstance().getId());
- all signals reach nodes inside the process. Event/Signal nodes are configured as "external".
Here are logs for invoking HTTP requests:

if I look /gwt-console-server/rs/process/definition/<my process id>/instances, i can see that they are not "signalable":
| {"instances":[{"id":"1","definitionId":"<process id>","startDate":"2012-03-27 20:31:13","suspended":false,"rootToken":{"id":"1","name":"","currentNodeName":"","children":[],"availableSignals":[],"canBeSignaled":false}}}]} |
But they have 3 signals defined inside process:
I've started looking and gwt console code and....
org.jbpm.integration.console.ProcessManagement:65
| result.add(Transform.processInstance(processInstance)); |
makes transformation, which basically omits canBeSignaled, availableSignals fields!
|
| ProcessInstanceRef result = new ProcessInstanceRef( |
|
|
| processInstance.getProcessInstanceId() + "", |
|
|
| processInstance.getProcessId(), |
|
|
| processInstance.getStart(), |
|
|
| processInstance.getEnd(), |
|
|
| false); |
|
| TokenReference token = new TokenReference( |
|
|
| processInstance.getProcessInstanceId() + "", null, ""); |
|
| result.setRootToken(token); |
|
| return result; |
ProcessManagementTest also lacks any tests:
@Test @Ignore
public void testSignalExecution() {
// TODO implement
}
Of course, I am not sure if this is the cause of ignoring signals. By looking at signal code it seems that processes should be signaled, however I could not setup development environment for gwt-console-server to trace exact behaviour (s.
Can anyone share experience with signaling processes running on gwt-console-server (Or a way to setup a debuging environment for gwt-console-server on eclipse)?
