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

[Ingold, Jonathan]

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
