[rules-users] Class Casting in a Collection data

2009-06-15 Thread VinuJay 

Hi my fact object looks like this,

class ProcessRequest {
 
  Long requestId;

  String processType;

  String assigneeUsers;

  HashTableString,Object businessData;

  //Getters and Setters

} 

My businessdata can be of type Integer, String, Boolean, hence i have used
generic Object for the business data value.

But if i use any mathematical operator in the rules (.drl) file like, 
rule Assign
when
p: ProcessRequest(processType == LoanFlowPlus 
businessData['LOANAMOUNT']  5000)
then
p.setAssigneeUsers(jcooper);
end


i get an error 
Exception in thread main org.drools.RuntimeDroolsException: Exception
executing predicate eval( businessData['LOANAMOUNT']  5000 )
Caused by: java.lang.ClassCastException: java.lang.Integer


Shouldn't the drools API handle this class cast conversion internally ..? or
how to specify the class casting in rules file

   What versions of Drools and MVEL are you using?
