This (stupid, unit test) rule:
rule "Testing contains"
dialect "mvel"
when
Response( $answerSelections : answerSelections )
AnswerSelection( answer.ID in (2, 3) )
then
System.out.println("Testing contains activated")
end
Produces this error:
java.lang.AssertionError: KnowledgeBuilder errors:
Unable to Analyse Expression answer.ID == 2 || answer.ID == 3:
[Error: Failed to compile: 1 compilation error(s):
- (1,9) unqualified type in strict mode for: ID]
[Near : {... Unknown ....}]
^
[Line: 1, Column: 0] : [Rule name='Testing contains']
Note the implicit rewrite going on. Clearly contains() is getting rewritten
internally to a long disjunctive (x == 1 || x == 2 || x == 3 and so on).
For whatever reason, in Drools 5.2.0-SNAPSHOT, this runs afoul of MVEL's
strict mode, which if I'm understanding things properly shouldn't be visible
to the .drl developer.
I know that Drools 5.2.0-SNAPSHOT is a mess at the moment but wanted to pass
this along.
Best,
Laird
