Until today, i've been using FB 3 Beta 1 but now i am forced to use Beta 2 since Beta 1 release expired today. I was working on the project which consists of HorizontalList in which i load images from remore url. Today i opened project in Flex 3 Beta 2 and got following error:

Code:

'smile_on.swf' is my application and 'http://www.sabljic-apartment.com/Smil/Shared/copyright.gif' is remote image that is loading in HorizontalList control. Image is loaded and displayed fine but i get above error after i click on it.

This application worked without any problems while i was using Flex Builder Beta 1 so i am in big trouble now and starting to panic. Can anyone help me with this error, how can i get rid of it?

thanks in advance
