Hi all,

We have an application that opens a modal dialog in IE to open aspx page that uses telerik controls. When using a single session, everything works fine. But using multiple of IE causes the error as in the screen-shot attached. Seems the script resources are not found for the other window but I'm not sure about that.

Any pointers would be appreciated. ‚Äč

Hello Avnish,

This is a server-side exception trapped as a JS error by the MS AJAX framework (this is how errors thrown during partial page rendering are shown).

Thus, I advise that you step through the code to see the actual exception and resolve it.

Hi Marin,

This error never occurs while debugging the code in VS. Only when the application is deployed to the test environment and opening multiple windows, this issue occurs.

Please suggest.

Hi,

My only suggestion at this point is to compare the two environments and see what is the difference that causes the problem (e.g., a different IIS configuration, some changes in the web.config, etc.).

Of course, if you can attach to the IIS and debug there, this will help you hunt the problem down.

You can also try using your local IIS and attach a debuger to it, instead of the IIS Express (or Cassini) server that VS uses by default.
