[rules-users] Rules not firing when facts asserted in a rule RHS in 5.0

[Wolfgang Laun]

We aren't seeing the code where the insertions happen, but I suppose that's
identical to
repeats of
   QuestionValidation qc = new QuestionValidation();
   insert( qv );

I'm sure you've also ascertained that the inserted value:QuestionValidation
is the very same type (including package) as the one used in rule "Test".

I would try and use a Java equivalent for the declared class
QuestionValidation,
just to see whether this is at the root of the problem.
