[Solved] Javascript "Unspecified error" after radcombobox within radajaxpanel async postback

[FL-Developer]

After radcombobox performs async postback within prometheus radajaxpanel, I get "unspecified error" js error.

I already changed my code back to using a regular radcontrols ajaxpanel, so I can't provide that.  There was a radgrid inside the panel as well, with enableajax=false.

Hello bzburns,

There are some bugs fixed since the Beta release of Prometheus RadAjax, so we will appreciate if you could send the problematic application via support ticket. We will test the code locally and investigate the issue with the latest internal build.

All the best,

I submitted a project as a support ticket to demonstrate different issues (radAjaxPanel not working when inside a asp:panel that was at some point not visible) - and it also demonstrated the "Unspecified Error."

If you make the asp:panel visible on the initial load the callback occurs but it produces the error.
