Conditional named consequences don't allow MVEL expressions in the condition of an if statement ----------------------------------------------------------------------------------------------- Key: DROOLS-324 URL: https://issues.jboss.org/browse/DROOLS-324 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 6.0.0.CR5 Environment: Mac OS-X 10.9, JBoss Developer Studio 7, Oracle Hotspot 1.7.0_45 Reporter: Duncan Doyle Assignee: Mario Fusco Labels: conditional, consequences, drools, mvel, named See this project, which is based on the standard Sample.drl of the Drools Eclipse plugin: https://github.com/DuncanDoyle/DroolsConditionalNamedConsequenceIssue As you can see in the 'src/main/resources/rules/Sample.drl', the first rule, which is commented out, uses an MVEL expression in the conditional 'if' statement, i.e. "if (m.status == Message.HELLO) break [sayHello]". The compiler throws this error: Rule Compilation error The field DroolsTest.Message.status is not visible. When I use a Java dialect and define the conditional if as " if (m.getStatus() == 0) break [sayHello]", as shown in the second rule everything works fine. Note that there is also an issue with using public constants in the condition, but I'll open another JIRA for that issue.
