Hi! I'm trying to write rules in Drools Expert. In the when part of the rule, I check
some properties of an Application object. This object contains a List and I would like to
check if a bunch of rules apply to all objects of SomeOtherType in this list. The rule
should fire only when the constraints are valid for ALL objects in that list. How could
this be done?
9:54 a.m.
Check out the forall conditional element:

Good luck!

Thanks. The object from the list are not in working memory though. Is it possible to
combine it with "from" keyword?

You can count (using the accumulate function) all objects of SomeOtherType.
Then, you can count (again, using the accumulate function) all object of
SomeOtherType meeting all the constraints.
For better performance (if this is an issue) you might use the stepwise form
of accumulate, ultimately returning a compound object containing both
counts, or implement a custom accumulate function.
