Just wondering what I should be doing.
In the past we've called it a low-priority bug, but we never decided
if it's a documentation bug or a code bug. One workaround could be to
subclass jess.Rete and override clear() to store and restore the
event mask (there's a Rete.listJessListeners() method you could use
to restore the event listeners, too).

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?
