5:38 p.m.
I have a rule and it is supposed to retract two objects
when
$objectOne : ObjectOne(...)
$objectTwo : ObjectTwo(...)
then
retract($objectOne);
#retract($objectTwo);
end
No matter what I do I can't ever retract objectTwo.
I put a print statement and it is there.
If I comment out the retraction of objectTwo it works fine.
I tried just retraction of objectTwo and that fails too.
I tried prefixing with drools.retract.
I get this:
com.principal.health.rules.RulesException: Root exception: [Error:
drools.retract($objectTwo): null]
[Near : {... Unknown ....}]

[Line: 1, Column: 0] - [Error: drools.retract($objectTwo): null]
