[Mono-list] XSP.EXE error: Missing method Add in assembly

[Raul Carolus]

When running my project, I click on a "Save" button of mine and get the 
following at the console:

** (/usr/bin/xsp.exe:24878): WARNING **: Missing method Add in assembly 
/mnt/www/bin/EditInstructing.ascx.dll typeref index 17

** ERROR **: file mini.c: line 3210 (mono_method_to_ir): assertion 
failed: (cmethod)
aborting...
Aborted


In my EditInstructing file, there is no "Add" method in this class, and 
none is referenced in the ascx file either.  I do use Add methods from 
NpgsqlCommand, though, but those are working in other files.

I don't really understand what is going on.  Can someone give me some 
pointers on how to get more detailed info from xsp?

Thanks,

Raul
