Variable on left of matches operator causes 'unable to resolve method' error ---------------------------------------------------------------------------- Key: DROOLS-882 URL: https://issues.jboss.org/browse/DROOLS-882 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.2.0.Final Reporter: Andrew Bickerton Assignee: Mario Fusco Fix For: 6.3.0.CR2 Attachments: MatchesTest.java Using a variable on the left of 'matches' fails in 6.2.0.FInal, when it worked in 6.1.0.Final. E.g. when Fact( $field : field ) RegEx( $field matches pattern ) results in [Error: unable to resolve method: defaultpkg.RegEx.$field() [arglength=0]] [Near : {... $field ~= pattern ....}] This can be worked around for the positive case by simply moving the constraint, e.g. when RegEx( $pattern : pattern ) Fact( field matches $pattern ) But it makes it impossible to find facts that are not matched by any regex, e.g. when Fact( $field : field ) not RegEx( $field matches pattern )
