I filed this because of discrepancy between Executable-model and Not executable-model Poosible choices are: - Fail even in case of Not executable-model - Success in case of Executable-model Additonal Note: If we miss a semicolon in action(), a more understandable error message is thrown. {noformat} [Message [id=1, kieBase=defaultKieBase, level=ERROR, path=r0.drl, line=2, column=0 text=Rule Compilation error Syntax error, insert ":: IdentifierOrNew" to complete Expression Syntax error, insert ";" to complete Statement]] {noformat}
