Model compiler cannot generate declaration from a function call --------------------------------------------------------------- Key: DROOLS-5548 URL: https://issues.redhat.com/browse/DROOLS-5548 Project: Drools Issue Type: Bug Components: executable model Affects Versions: 7.31.0.Final, 7.32.0.Final, 7.33.0.Final, 7.34.0.Final, 7.35.0.Final, 7.36.0.Final, 7.37.0.Final, 7.38.0.Final, 7.39.0.Final, 7.40.0.Final Reporter: Ciprian Chiru Assignee: Luca Molteni Priority: Major Given the example rule below (based on the drools example rule)   {code:java} global java.util.Set controlSet; declare A x: String end declare B a: A end function String dummyFunction(B b) { return "test"; } rule "will execute per each Measurement having ID color" no-loop when Measurement( id == "color", $colorVal : val ) $b: B() $val: String() from dummyFunction($b.a) then controlSet.add($colorVal); end{code}     When compiling the rule with _kie-maven-plugin_ it fails with : {noformat} ...target/generated-sources/drools-model-compiler/main/java/rules/Rules5937a2896da74f01bfa36d294bcf0858RuleMethods0.java:[32,107] cannot find symbol [ERROR] symbol: variable $b [ERROR] location: class rules.Rules5937a2896da74f01bfa36d294bcf0858RuleMethods0{noformat} It transpiles and compiles fine with:  {code:java} $val: String() from dummyFunction($b){code}   This can probably be reproduced on all version.  It works when the rules are not pre-compiled.
