Hi Nithya,

Just checked and found that everything seems to be working fine. I am not sure, why it is not working on your machine.

Run the attached example on your machine and see if it is working. I made slight changes like, removed cellRenderer="Thumbnail" from TileList attributes because I don't have Thumbnail renderer.

But if it runs there then your code might have some problems...

So your app.mxml loads first and on clicking some button popup.jsp is opened in a frame?

It is not working, because app.mxml might be loading after popup.jsp?

Nithya,

It is tested code and it worked for me. I don't post code without testing, but I guess there might be some other problem. Can you please post your code again, I want to see how have you incorporated it?

Also tell us the flow of application, how popup is opened etc.
