[Mono-dev] Regression in System.Web

[Joe Audette]

Hi All,

I'm seeing a problem on the UserProfile page in mojoPortal. It was reported to me by a user running the latest release of mono and I am also seeing it in the latest build of mono from svn r58211

The code in this page hasn't changed in a while and was working without error a while back. Tonight I tried putting try catch statements around all references to DropDownList controls but I still get the error.

This is using  apache2 on Suse 10 fully up to date.
The user of mojoPortal who reported it to me was using Ubuntu, mono 1.1.13.4 and apache2

I'm not entirely sure what line of code its happening on but the error is:

System.Web.HttpException: DropDownList only may have a single selected item
