Mitch,
The problem is this isn't something we can answer quickly. As we will
need to get the example running and delve deep - so it will get
scheduled along with the other bugs we need to look into. If there isn't
a jira for it, the chances are it might be forgotten. The same is true
for the enhancement reqeusts for the Audit View.
The ideal thing for self contained tests is they should unzip into our
drools-examples project so we can run them out of the box, like the
other examples. Even better still attach a patch to fix the error :)

No Problem.
But does posting a JIRA preclude getting answers to my questions regarding
the Audit view?

no we *really* need to be able to reproduce it with a test. otherwise its
hours of guess work, versus minutes of finding out what the problem is. We
would then add it to the integration suite to make sure it doesnt' regress
again.

Hey,
Unfortunately I continue to get the NPE. I would be happy to post the
problem to a JIRA, but before I do I have a few questions, the answer to
which might help me in my ability to characterize the problem.
First off, it would be great to be able to copy from the Audit view. :)
Also, the Audit view doesn't seem to wrap. It chops off the right edge of
long lines even after I scroll fully to the right.
Now, I assume that the number(s) in parenthesis at the end of each
activation message in the Audit view is the equivalent of a fact-id? If
so,
would it be bad to have a (-1) show up? It does show up, but often enough
that I'm not sure it's a problem.
I've attached the event.log file in case that might help.
Also, what exactly should I attach to the JIRA? Should I ZIP up the
entire
(though rather small) Eclipse project?
Thanks again for your help.

if you are still getting it, would be be possible to bundle up a self
contained test and attach it to a JIRA?
As it is, we can't reproduce it, but would like to !

Hey,
I was cranking along writing rules when all of a sudden JUnit reported
an
NPE (see below) during WorkingMemory.fireAllRules(). The rule
referenced
in
the stack trace is as follows,
rule "Add report periods to the FEQueryList"
when
tr : TimeRange(level == TimeRange.FE, durationInMillis > 0 )
ctx : HashMap()
eval(ctx.containsKey("FEQueryList"))
then
System.out.println("Adding FE period to the list");
Vector v = (Vector)ctx.get("FEQueryList");
HashMap m = new HashMap();
v.add(m);
m.put("st", new Long(tr.getStartTime()));
m.put("et", new Long(tr.getEndTime()));
m.put("relation", "PMI_FE");
retract(tr);
end
The NPE occurs on the retract() on the last line of the consequence.
I'm not exactly sure what to do about it. I suppose I could look at the
code.
Any suggestions?
Thanks.
