Whilst developing within Atlas UpdatePanels we've twice come across the following error following autopostback on standard WebControls. Actually the error seems to sneak up onus, meaning that the control will postback perfectly well - Atlas enabled - then breaks a little down the line.
The javascript error message is:
#########################################
Line: 11245
Char: 17
Error: Unknown runtime error
Code: 0
Url: http:/localhost:1084/theWebPage/aspx
#########################################
Line 11245 is not a line in the resulting HTML source, so we've no idea where this error occurs. Also stepping through the code does not provide any answers, since all lines of code-behind execute perfectly: including the post back event catch for the control causing the problem. The controls affected so far are the ListBox and DropDownList control. In the first case the selectedIndexChange event was simply enabling a "Remove item" button for the selected item. In the second case the same event handler was being asked to set a Property value from the SelectedValue: so nothing complex is happening in the code. It's also worth saying that on other pages dropdownlists postback inside UpdatePanels within this error occuring.
We've managed to code around the problem so far, essentially by not allowing the control to postback and handling the desired functionality a different, but less satisfactory way. However as development continues I can see this error occuring when there is no other way to avoid the postback.
Therefore any information or suggestions on how to go about trying to solve the bug would be great.
The error is happending within: VS2005PE; IE6; April CHP
On a different note: thanks for the continuing work on this platform. We love how easy it is making creating "ajax-like" behaviour on our web apps.
