Having spent all day on this one, I have finally got to the bottom of it.
The problem is reproducible if I have /both/ a declarative fact model
/and/ a function in my rules.
It doesn't matter whether the function is called or not... It's presence
is enough to cause the problem.
Any rule that is dependent on the existence of an instance of the
declarative fact model where the instance is created in the RHS of
another rule will not fire.
I suspect that this is a bug that has been fixed in 5.1 because I have
been using this technique in Drools 5.1... It's only since downgrading
to the (supported) JBoss Rules 5.0 that I have experienced the problem.
Does anyone know if there is a fix in the 5.0 branch?
If I create a "real" Java class and upload it in a jar file to the
Guvnor and use that in place of the declarative model then the problem
does not happen.
This is a workaround in the short term but I would much prefer not to
have to do this.

Yes the package is "SWWB2BOutgoing" but it looks as though the package
name simple doesn't get reported in the log file.
I have been debugging through this thing and where I've got to so far
is that I am getting two (and maybe more) entries for the class
"SWWB2BOutgoing.QuestionValidation" in the
ObjectTypeConfigurationRepository.
So my current question is "How is this possible?" Is it maybe a
classloader issue?

I can see the facts being inserted in the log as follows

Shouldn't the package name appear in the log as well?
However, if I insert a QuestionValidation fact created in Java by
using
kbase.getFactType("SWWB2BOutgoing", "QuestionValidation") then
the Test
rule gets fired just fine.
That is, apparently "SWWB2BOutgoing".
