[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1581) Invalid dialect name causes NullPointerException in BRMS and Eclipse plug-in rule editor

Invalid dialect name causes NullPointerException in BRMS and Eclipse plug-in rule editor ---------------------------------------------------------------------------------------- Key: JBRULES-1581 URL: http://jira.jboss.com/jira/browse/JBRULES-1581 Project: JBoss Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-brms, Eclipse IDE Affects Versions: 4.0.4 Environment: Windows XP SP2, Sun JRE 1.5.0_13 Reporter: Shahad Ahmed Assigned To: Mark Proctor Fix For: 4.0.7, 5.0.0-M1 If you specify an invalid dialect attribute in a rule, or as a package dialect then the eclipse plug-in (and also BRMS) reports a java.lang.NullPointerException Either one of the two dialect used in the example below causes the NullPointerException: package defaultPackage import java.lang.Integer; dialect "javaxxx" rule "Examaple" auto-focus "true" dialect " javaxxx " when p : Integer( intValue == "10" ) then retract( p ); end In the BRMS if you try to validate the above rule or build the package you get an error with the stack shown below. It's not really a big issue other than the fact that the error message gives you absolutely no clue as to the cause of the error, or where it is located. It's only when I looked at the source code that I realized it was due to an invalid dialect name. An error occurred executing the action.
