Issue with displaying ALV in a popup window

Hi Experts,

I am trying to create an popup window with an ALV in it. TO display the ALV i have defined the component usage for SALV_WD_TABLE component.When the ALV is displayed for the first time it shows up correctly with required data. When i try to display ALV popup again only the popup window frame gets displayed the ALV is missing from the popup window.

If i refresh the main component by clicking browser refresh buttion and then click for ALV popup dsplay i get the correct popup display the first time and then agin the same issue.

Has anyone else come across this issue before. All your suggestions, responses are welcome.

Thanks,

Vivek
