CL_GUI_ALV_GRID refresh problem

Hi all,

I've been checking all the post but now answer found for my problem.

I have an ALV OO and when I display the data all is correct. But, when I come back to the selection screen and I change the selection and execute, the old data still appears.

I free all the objects and refresh internal table with new data, but after execute CALL METHOD g_grid->set_table_for_first_display, the old data still is there.

Any clue?

Regards.
