             Summary: Combining custom operators with OR results in compile error
                 Key: JBRULES-3517
                 URL: https://issues.jboss.org/browse/JBRULES-3517
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-compiler (expert)
    Affects Versions: 5.4.0.Final
         Environment: Drools.5.4.0
Java.1.6
Linux

            Reporter: Stathis Rouvas
            Assignee: Mark Proctor


I recently migrated from Drools.5.0.1 to Drools.5.4.0 and I am having issues when combining constraints with OR when custom operators are involved.

For example, the following rule:

rule "r548695.1"
  no-loop  true
  dialect "mvel"
when
  gnId : GN()
  la : t547147(   )
  v1717 : Tra48( gnId.gNo==gNo , name F_str[startsWith] la.c547148 || postCode F_str[contains] la.c547149 )
then
  System.out.println("Rule r548695.1 fired");
end

results in the following exception:

Unable to Analyse Expression gnId.gNo == gNo && ( F_str0.evaluate( name, la.c547148 ) || F_str1.evaluate( postCode, la.c547149 ) ):
[Error: unable to resolve method using strict-mode: my.package.rulez.Tra48.F_str0()]
[Near : {... gNo == gNo && ( F_str0.evaluate( name, la.c54 ....}]
                             ^ : [Rule name='r548695.1']

Please note, that the same rule using AND (&&) between the custom operators compiles OK.

The above rule had not problem whatsoever in Drools.5.0.1.
