[rules-users] Issue with nested objects (Repost from message with no subject so that there is a subject)...

[Jason Partyka]

So it turns out my issue has something to do with rule-flow groups. I'm invoking the WorkingMemory.startProcess(String) method, with a parameter of "QuoteBuilder" to invoke the proper rule-flow, but I'm getting an error that says there is no such process id.

I know I am adding the proper .rf file when I build the pacakge and no error is occurring when I do that.

Subject: [rules-users] Issue with nested objects (Repost from message with no subject so that there is a subject)...

Hi all,
I'm having an issue with my rule and Drools 4.0.4. The object that my rule is supposed to reason over has nested objects and Drools does not appear to be reasoning over it when I modify attributes. I've pasted the rule at the end of the e-mail. I am attempting to change the value of the ez_width and ez_drop properties and have the corresponding rule below invoked.
I have tried to use the StatefulSession.modifyRetract(FactHandle) and StatefulSession.modifyInsert(FactHandle, Object) methods, which I expected to work. I then, for the sake of trying, tried the StatefulSession.update(FactHandle, Object) method.
After both, I've tried StatefulSession.fireAllRules() as well and nothing.
It's possible I'm missing something in the rules editor but I do not know.
Any insights?
Thanks,
Jason
