org.drools.rule.InvalidPatternException: "Required Declarations not bound" when
using MVEL, and OR-ing evals together
----------------------------------------------------------------------------------------------------------------------
Key: JBRULES-2526
URL: https://jira.jboss.org/browse/JBRULES-2526
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-core (expert)
Affects Versions: 5.1.0.CR1
Reporter: Chris DeLashmutt
Assignee: Mark Proctor
Attachments: mvel-declarations-problem.zip
There is an issue when using multiple groups of OR'd evals and the mvel dialect.
Drools is throwing an InvalidPatternException complaining that there are unbound
declarations. During tracing, it seems that the declaration was actually found, but
offset for the pattern that is resolved in BuildUtils.checkUnboundDeclarations() line: 239
isn't <= the offset of the pattern that was passed in with the declarations to the
method.
Here is the rule:
rule "MVEL with OR groups and Evals"
when
$fieldB: Field(name == "fieldB")
$fieldC: Field(name == "fieldC")
$fieldD: Field(name == "fieldD")
$fieldE: Field(name == "fieldE")
(
eval($fieldB != null)
|| eval($fieldC != null)
)
(
eval($fieldD != null)
|| eval($fieldE != null)
)
then
insert( new Result("Found") );
end
Here is the stack trace:

Edson Tirelli resolved JBRULES-2526.
------------------------------------
Fix Version/s: 5.1.0.CR1
Resolution: Done
Thanks for reporting and providing the test case.
The problem was that eval statements were not properly cloned for each logical branch.
That was not a problem for the java dialect that uses "stateless" expressions,
but MVEL dialect caches declarations and when wiring them, each logical branch was
overriding the wired declarations of the previous logical branch.
Fixed.
