[rules-users] Guvnor's Scenario returning "Error rebuilding RuleBase"

Hello, I am receiving an "Error rebuilding RuleBase" error in Guvnor anytime I run a scenario against rules that reference a constant. Also the constants are not available in the scenario tool. An example of a rule that I have used that references a constant would be: *********************************************** rule "First" salience 10 when $a : Action(task == ConstantC.UNO) then System.out.println("First Rule Fired"); end ************************************************* Note "task" is a ConstantC object. The constant UNO is declared in my java class with the line: ******************************************************************* public static ConstantC UNO = new ConstantC(1, "One"); ******************************************************************** The rule fires perfectly in Eclipse with the expected result. Could this possibly be a bug with Guvnor? I couldn't find anything in JIRA relating to this. Any input is appreciated! Thanks, Jon
