Hi my fact object looks like this,

class ProcessRequest {

 Long requestId;

 String processType;

 String assigneeUsers;

 HashTable<String,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
