In the doc, it says to use the JessEvent.CLEAR to re-set up your event mask
on the engine (section 10.11 in the 7.0p1 manual).
"One added wrinkle: note how the handler for JessEvent.CLEAR sets the event
mask. When (clear) is called, the event mask is typically reset to the
default. When event handlers are called, they have the opportunity to alter
the mask to re-install themselves. Alternatively, they can call
removeJessListener() to unregister themselves."
The example shown is:
case JessEvent.CLEAR:
Rete engine = (Rete) je.getSource();
int mask = engine.getEventMask();
mask |= defaultMask;
engine.setEventMask(mask);
// MyGUI.clearDisplay(
break;
What I found out is in the Rete.clear() method:
broadcastEvent(JessEvent.CLEAR, this, null);
setEventMask(0);
So, whatever handlers are doing when handling CLEAR, the event mask is going
to be zero'd out after they set it.
Is this a bug, or is there another mechanism that I can use to reset the
event mask when the Rete is clear'd?
