Operator field and the fact's variable field required in the "then" part of the rule
------------------------------------------------------------------------------------

                 Key: JBRULES-1121
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1121
             Project: JBoss Rules
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: drools-brms, Eclipse IDE
    Affects Versions:  4.0.0.GA
         Environment: drools-jbrms stand alone and Eclipse drools-4.0.0 
            Reporter: sreeni sabapathy
         Assigned To: Mark Proctor
            Priority: Minor
             Fix For: FUTURE


In the drools-jbrms standalone and even in the eclipse plugin version of "New guided drl file"
the "then" part of the rule has the limitation of assigning the fixed value to the fact's variable.
But in many condition the the value of the variable depends upon the value of another variable.

I have taken  a simple example for explanation.

For calcluating simple interest

SI = P*T*R/100

Now in the rule file if the 

"when" condition as the check of " Calcluation type (simple ineterst or compound interest)"

"then" part having SI, 

At the present drool-jbrms definition the 

"then" part has SI = text field.

But my requirement is to look up the class variable "principle", "Time" and the "Rate" and then calculate, not just 
assign some fixed values.

In a simple sentence I would appreciate if the drools- jbrms has the options related to  "when" in the "then" part of the rule also.
