executable-model: compilation fails if there are multiple update() for the same object in RHS. ---------------------------------------------------------------------------------------------- Key: DROOLS-3574 URL: https://issues.jboss.org/browse/DROOLS-3574 Project: Drools Issue Type: Bug Components: executable model Affects Versions: 7.14.0.Final Environment: - RHDM 7.2.0 Reporter: Hiroko Miura Assignee: Luca Molteni Priority: Minor Labels: support Attachments: HelloWorld.zip compilation fails with the following DRL. {noformat} package com.sample; //generated from Decision Table import com.sample.Message; // rule values at C11, header at C6 rule "HelloWorldXLS_11" when m:Message(status == Message.HELLO) then System.out.println(m.getMsg()); m.setMsg("Goodbye cruel world");update(m); m.setStatus(Message.GOODBYE);update(m); end // rule values at C12, header at C6 rule "HelloWorldXLS_12" when m:Message(status == Message.GOODBYE) then System.out.println(m.getMsg()); end {noformat} Here is an ERROR. [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile-1) on project HelloWorld: Compilation failure [ERROR] /tmp/HelloWorld/target/generated-sources/drools-model-compiler/main/java/com/sample/Rules47274848713b466c9cc49fe299a57c35RuleMethods0.java:[76,40] variable mask_m is already defined in method rule_HelloWorldXLS__11() and problematic source which is generated. {noformat} public static org.drools.model.Rule rule_HelloWorldXLS__11() { final org.drools.model.Variable<com.sample.Message> var_m = D.declarationOf(com.sample.Message.class, "m"); final org.drools.model.BitMask mask_m = org.drools.model.BitMask.getPatternMask(com.sample.Message.class, "msg"); final org.drools.model.BitMask mask_m = org.drools.model.BitMask.getPatternMask(com.sample.Message.class, "msg", "status"); org.drools.model.Rule rule = D.rule("com.sample", "HelloWorldXLS_11").build(D.pattern(var_m).expr("$expr$1$", (_this) -> _this.getStatus() == Message.HELLO, D.reactOn("status")), D.on(var_m).execute((drools, m) -> { System.out.println(m.getMsg()); m.setMsg("Goodbye cruel world"); drools.update(m, mask_m); m.setStatus(Message.GOODBYE); drools.update(m, mask_m); })); return rule; } {noformat} If first update() (which is just after m.setMsg()) is removed, compilation works.
