Description Nic Wise 2012-06-07 13:05:12 UTC

1. Make a new universal project (might be iphone, too)
2. edit the xib
3. add some stuff to it, including outlets and actions
4. save in xcode
5. switch back to monodevelop
6. get this error:

System.InvalidOperationException: Both arguments to IsDerivedFrom() must be from the same compilation.

I suspect this is the same issue that  Elena inpasarable@gmail.com is having on the list (Jeff!!)

HOWEVER: actions etc are all updated fine, and the error doesn't happen second time around.
Comment 1 Nic Wise 2012-06-07 13:24:19 UTC
I stand corrected. When I went back into xcode, all the actions are gone. Nothing in the generated obj-c code (tho they were in the generated class in c#) :(
Comment 2 Karl Heinz Brehme Arredondo 2012-06-07 16:49:39 UTC
I have this problem too: the error message, that cleaning project it run ok at least one time, and the lost of some actions (not all).
