Rule compilation can fail when using an attribute/method of OOPath provided variable ------------------------------------------------------------------------------------ Key: DROOLS-2135 URL: https://issues.jboss.org/browse/DROOLS-2135 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.4.1.Final Reporter: Peter Mačkay Assignee: Mario Fusco Priority: Minor Having a test like this: https://gist.github.com/mackaypeter/d8b576ce34d42794da559308b1854aff Produces the following error: {code} Unable to Analyse Expression this.getName() == "joe": [Error: unable to resolve method using strict-mode: org.drools.compiler.oopath.MyTest$Parent.getName()] [Near : {... this.getName() == "joe" ....}] ^ [Line: 4, Column: 2] : [Rule name='R'] {code} It seems like it tries to look for the method definition in the Parent class instead of the Child class. The rule works correctly when there's a getName method defined in Parent. Meaning the rule compiles and fires correctly.
