[jboss-jira] [JBoss JIRA] (JBRULES-3517) Combining custom operators with OR results in compile error

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: Mario Fusco Labels: custom_operator Attachments: F_StrEvaluator.java, F_StrEvaluatorDefinition.java 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.
