How to close FPM GAF application on custom event

Hi All,

I need a help to close the FPM window when user clicks on WDA custom button, for ex: when user selects a value from dorpdown a custom web dynpro pop up will comes up..if user select Ok button I want close the entire FPM application, so can I achieve this.

Ok is the custom action in web dynpro, is there any way I can trigger this action to FPM Override or Process_event.

Or is there any suggested way to do.

Thanks
