I have some trouble understanding how conditions and constraints are evaluated:
I have a rule flow split node with constraints on a global object. The split node always
takes the same path like if the constraints are evaluated at the beginning of the
execution of the process and not when the process flow reaches that split node. What I
would expect is that the split node constraints takes into account the state of the global
object as modified by previous rules in the flow.
Am I right to think that rules conditions and split nodes constraints are evaluated only
when inserting/updating objects in the working memory? The documentation is not really
useful (unless I haven't found the appropriate one).
Thanks
André

Thanks for trying this for me...
As it turns out, while I was creating a test sample for you I realized
that my ruleflow was not loading properly and I forgot to check for
errors on the builder. Now it works.
Still, the behavior is strange. If my rule doesn't load and even though
my DRL loaded, my globals were not available. Since the DRL declared the
same globals it should not have given me that error.
Thanks

Andre,
There should be no problem in using the same global in both your rules
and processes.
I have tried a simple example as you described but have not been able to
reproduce the problem. Could you send me a self-contained example that
shows the issue?

Quoting "Malenfant, Andre" <andre.malenfant(a)cgi.com>:
I am experimenting with rule flows and I get the following error:
Unexpected global [myglobal]
When calling setGlobal on the session.
This code works without the workflow (globals declared in the drl)
but
fails when I include the rule flow. I declared the same globals in
the
rule flow in the header section.
