FPM : Event Processing

Dear All,

I am developing an application in FPM, i am having 2 form UIBBs and 1 List UIBB. All these UIBB are part of same feeder class.

Now there is a button call SAVE on the screen. Whenever I am clicking on it, Feeder class form~get_Data is trigger where I have written my SAVE logic. the get_data method is executed twice for my 2 form UIBB. So is there any way to Know the event is already executed ?

what is standard practice ? Where should i write the code Process Event or Get Data ??

Thanks In Advance,

P$G.
