While trying out some things in the Eclipse modeler & testing w/ unit tests, I've run into some issues w/ early experimentation. This is likely to be the first of some posts as I try to model what we need in our business execution & find out what is feasible.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The above is an example of a simple workflow I have that have that terminates early before I can send in an event that will trigger the 'Main task'; acc.to the documentation '</p><p><a class="jive-link-anchor-small"><p>A Signal Event should have no incoming connections and one outgoing connection' (<a class="jive-link-external-small" href="http://docs.jboss.org/jbpm/v5.1/userguide/ch05.html">http://docs.jboss.org/jbpm/v5.1/userguide/ch05.html</a>),  suggesting that this workflow should wait for a signal event of the type expected before executing the 'Main task' and then terminating. What I am seeing in my unit test is that after executing the 'Initial' task, the process instance is in a 'STATE_COMPLETE' (2) state. Further code that signals events w/ the expected event type (ksession1.signalEvent(....)) does not trigger execution of the 'Main task' (nor does it throw any exceptions or errors). </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Some snippets from my test & log below :</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><table><tbody><tr><td style=";"><br/></td><td style=";"><br/></td><td style=";">ProcessInstance pi = ksession1.startProcess("unknownQC");</td></tr><tr><td style=";"><br/></td><td style=";"><br/></td><td style=";"><br/></td></tr><tr><td style=";"><br/></td><td style=";"><br/></td><td style=";">long pid = pi.getId();</td></tr><tr><td style=";"><br/></td><td style=";"><br/></td><td style=";">System.out.println("Process instance started ... id = " + pid);</td><td style=";"><br/></td><td style=";"><br/></td><td style=";"><br/></td><td style=";"><br/></td></tr><tr><td style=";"><br/></td><td style=";"><br/></td><td style=";">boolean stillActive = ProcessInstance.STATE_COMPLETED != pi.getState();</td></tr><tr><td style=";"><br/></td><td style=";"><br/></td><td style=";">System.out.println("Process still active ?

Am I missing something obvious ?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The above btw is a simplifcation of a larger workflow I'm working on, which will require being able to accept multiple events of any type (and multiple of the same tyoe) at any time before terminating if an event of a certain type is receievd ... but baby steps, I want to know why the above doesn't work so I can plan accordingly on what constructs I have at my disposal.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks !</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>PS. I'm placing this in the jBPM 5.2 category b/c there is no 5.3 one (can somone add that please?), and taggint it w/ jBPM 5.3.0.final</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p></a></p></div>
