Hello,
I attached the source of an ASP.Net page where I create Accordions
dynamically through a database binding. The page works fine with IIS,
but fails with xsp2 + mono 1.2.5 + System.Web.Extensions SVN. I get this
error:
The TargetControlID of '_AccordionExtender' is not valid
The value cannot be null or empty.
I'm not sure which element as the ID '_AccordionExtender'
Thank you
Julien
