Mark Proctor reopened JBRULES-1433:
-----------------------------------

             
My mistake, this is actually an MVEL issue. MVEL is used to evaluate the 'from' statement. Within it's scope of understand it thinks it can narrow the bigdecial to an integer without losing any precision. I'm not sure how to fix this one at the moment.
