ALV Grid does not refresh

Hi everybody,

I use an ALV Grid on a Dynpro screen, go on to other screens and later jump back to the first screen. When jumping back I clear all reference variables to the ALV Grid, container and internal table. I build everything up from scratch again and even call Refresh_Table_Display again. Strangely enough, I still see old data in the "new" ALV grid on the screen (including marked checkboxes) - although I can see in the debugger that the internal table holds the correct updated data. The only help is pushing the "Refresh" button of the ALV grid. As this may confuse users, I am looking for a better solution - does anyone have a hint for me?

Thanks a lot,

Ringo
