Hi, This is what used to work in Drools 3: Sample from DSL: [then]A validation error has occurred=ValErrTO valErrTO = new ValErrTO(); java.util.HashMap variableMap = new java.util.HashMap(); [then]- The standard error level is "{standard_error_level}"=int stdErrLevel={standard_error_level}; valErrTO.setErrorCode(stdErrLevel); With Drools 5.2.1 it gives me the following error: No modify was found to add the modifier to: - The standard error level is "400" How do I write the above 2 statements again in Drools 5.2.1, NOTE: I need to write this in DSL. Sample DSLR: rule "Your First Rule" when There is a Coverage with then #actions A validation error has occurred - The standard error level is "400" end Thanks, saleem
