When I test that view in the project manager I'm able to save the changes made.

When I want to update through my form I can't. I have an error message saying that "the key columns for the update table is not specified". The view is marked as updateable, The primary key field is defined and the field that does'nt want to be updated is defined also as updateable.

That view was not made with the view designer. I used ViewEdit to do it. I also have eView and Stonefield Database Toolkit. Everything looks good to me when using all of these tools.

Anybody have a clue on this one?
