Having spent all day on this one, I have finally got to the bottom
of it.<br>
<br>
The problem is reproducible if I have <i>both</i> a declarative
fact model <i>and</i> a function in my rules.<br>
It doesn't matter whether the function is called or not... It's
presence is enough to cause the problem.<br>
<br>
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.<br>
<br>
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.<br>
<br>
Does anyone know if there is a fix in the 5.0 branch?<br>
<br>
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.<br>
This is a workaround in the short term but I would much prefer not
to have to do this.<br>

Yes the package is "SWWB2BOutgoing" but it looks as though the
package name simple doesn't get reported in the log file.<br>
<br>
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.<br>
So my current question is "How is this possible?" Is it maybe a
classloader issue?<br>

I can see the facts being inserted in the log as follows<br>

Shouldn't the package name appear in the log as well?<br>

However, if I insert a QuestionValidation fact created in

kbase.getFactType("SWWB2BOutgoing", "QuestionValidation")
then the Test<br>

That is, apparently "SWWB2BOutgoing".<br>
