Hi Rene,
most of the times the new event classes you are adding automatically have
the right TYPE value (declared in the class BpelEvent) because you place
them in the class hierarchy. For example when your class extends the class
ActivityEvent the TYPE of the new event class is automatically
activityLifecxycle. This is the case because the method getType in
ActivityEvent is implemented to return this TYPE.
The classes with names in capitals like ACTIVITY are implementing the
behavior of the different BPEL constructs. So, if you want to throw a new
event it must happen in such a class. The class you place your new event in
must also extend the class ACTIVITY because the method sendEvent is
implemented there.
In order to place your event in the right class, just debug through the
classes and find a suitable position for it. For example I inserted a
LinkSetTrue event in the run method of the class TCONDINTERCEPT because
there was code that evaluated link conditions:
boolean val = evaluateTransitionCondition(olink.transitionCondition);
linfo.pub.linkStatus(val);
//Check if linkstatus was set to true or
false
if (val) {
//Before a link is set to true we have
to throw an event.
LinkSetTrueEvent linkSetTrueEvent
= newLinkSetTrueEvent();
sendEvent(linkSetTrueEvent);
} else {
//Throw an event when a link is set to
false
LinkSetFalseEvent linkSetFalseEvent =
new LinkSetFalseEvent();
sendEvent(linkSetFalseEvent);
}
Hope that helps
Daniel
