Autosave in webdynpro ABAP

Hi Experts,

I am working on enabling auto-save functionality in our ESS/MSS wda application.

I am using timed trigger element to call save method. so after period i call my save method where i have written below code.

DATA: lo_fpm TYPE REF TO if_fpm.

lo_fpm = cl_fpm_factory=>get_instance( ).

• Trigger FMP save event

lo_fpm->raise_event_by_id( 'BTN_SAVE' ).

The save works fine if i remove focus MANUALLY from textedit box to some other element of view. but if i write something in textedit box & left cursor over there then save doesnt work.

Could you pease suggest any solution?

Thanks in advance ,

Sachin
