How to read the Lead Selection in Search UIBB

Hello,

I have a Search UIBB implementation with the list from Search UIBB.

When the user double click any line in the List we want to call another program.  Not sure how to read the Lead selection. I see the event ID FPM_RESULT_LEAD_SEL  in Process_Event method and GET_DATA method but not sure how to get the actual line.

Thanks in advance for any help.

Regards,
PK
