CL_GUI_TIMER

Hi,

I have a great problem with the class CL_GUI_TIMER. We want to use this class to refresh a CL_GUI_ALV_GRID after i.e. 10 seconds. Therefore I wrote an eventhandler which reacts on the event FINISHED of the timer by refreshing the grid an starting the timer once again. But when a modal windows was opened then framework seems to block the event (it's a system event) an the timer stops. I've enhanced the timer to react on the event himself but that doesn't help.

Have anybody a solution for this problem?
