Hi there, 

 

Sometimes I get the error mentioned on subject on firebug. Seems to happen when open a window (radwindow) with the component within. then you close the window and then open it again, the component select files button seems freezed and when you click it that error appear.

 

It fixes when you do a postback on the window. 

 

Is there some way to fix or avoid this issue? 

 

Thanks in advance.
