Hi,
Well, I bet this is a similar kind of thing to the previously-reported
problem. I'll give you a patch for Jess, you rerun your problem, and
see if any previously-unreported exceptions show up. Note to casual
readers: this is -not- a patch I'm recommending that everyone make:
this is just a debugging hack.
In jess/ReflectFunctions.java, at around line 1025, there is a finally
block. Modify it to look like this:
finally
{
// Regardless of what happens, we need to assert this now, since
// we retracted it before!
if (keepID)
fact = m_engine.assertKeepID(fact);
else
fact = m_engine.assert(fact);
}
// Note: add this line outside the finally block
return fact;
Recompile Jess, try your example again, and let me know what happens.
