[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
