Hi Felipe,

 

When you define your LHS in the BRMS, there is an option to assign a variable to the expression. In the When part, there should be a little green triangle beside Person. Click on this to get a dialog called "Modify constraints for Person". At the bottom of this dialog is an option to set a variable name to bind to Person. Type p, or whatever you want into the text box and then click the Set button beside the text box. You should now have a LHS constraint of the form p:Person(...). Now create a Then action by clicking the + at the RHS of the Then part. A dialog will appear called "Add a new action". The first two option allows you to pick the variable p you just created - you probably want the second option of "modify a fact" as you want to call update(p) after modifying p. You should now see something like Set [p] in the Then part. Click on the Green triangle above Set [p] and you will get a dialog called "Add a field" with a list of the fields in the Person class. Choose the one you want to set (approvedMount?). What this does is actually call the method called setApprovedMount (Press View Source button to see). The Set action should now have a text box where you can enter the parameter $income * 1.2.

 

I've had a look at the source code for this functionality and it only allows Setter methods to be called - unfortunately you cannot call any other methods on Person.

 

Regards

Shahad

Ok, so to fit on the "not ignored emails" from the list Mark posted, I changed the title. However I following in the list 

anyways beacuse Im resending this email in less than 3 days. 

 

Note: Im not desperate, nor this is for today. This just came out today yesterday and well... its important to me, but I

think I can get a work around for now.

 

So here is the real on-topic question.

-----------------

Anyone knows how to use variables (from fields) setted on LHS, to modify a field on the RHS using the GUI editor

from BRMS?

 

What I need is to write this rule on BRMS.

 

rule "Set approvedMount for a women"

no-loop true

when

$p: Person($sex: sex == "F", $income: incomeMount)

then

$p.setApprovedMount($income * 1.2);

update ($p);

end

 

I know I can use formulas, but I only know how to set those on LHS, I dont know how to put a formula on RHS (setter of the field to modify).

 

Thanks.
