Having just looked in the Drools JIRA repository, I pretty sure that
it is the same issue as was reported in <a
href="https://jira.jboss.org/browse/JBRULES-2140">JBRULES-2140</a>.<br>
That entry has a repro.<br>
<br>
I am interested as to what you mean by "right around the corner"?<br>
<br>
Here is a repro anyway...<br>
<br>
<QUOTE><br>
package rulestest<br>
global java.util.logging.Logger logger<br>
<br>
declare QuestionValidation<br>
question: String<br>
mandatory: Boolean<br>
state: String<br>
type: String<br>
end<br>
<br>
function void testfunc() {<br>
System.out.println("testfunc called");<br>
<br>
}<br>
<br>
rule 'init'<br>
dialect "mvel"<br>
when<br>
eval(true)<br>
then<br>
QuestionValidation qv = new QuestionValidation();<br>
qv.setState("ss");<br>
qv.setQuestion("qq");<br>
insert(qv);<br>
logger.info("Hello world");<br>
<br>
end<br>
<br>
rule 'test'<br>
dialect "mvel"<br>
when<br>
$qv: QuestionValidation()<br>
then<br>
logger.info("Found a qv " + $qv);<br>
<br>
end<br>
</QUOTE><br>
<br>
If the testfunc is present then the "test" rule never fires. If it
is not present then the "test" rule fires just fine.<br>

Hi Chris, could you attach the repository export xml from your
repo that I can use to reproduce the issue with? BRMS 5.1
(supported bits) is right around the corner and I would be able to
tell you if the issue still persists with the currently tested
bits for 5.1.<br>
<br>
Thanks.<br>

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>

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

That is, apparently "SWWB2BOutgoing".<br>
