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.

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.
