MVC2 : Troubles in edit state with modelstate using a structure

I have the following problem. I'm using a structure (not a single table) to display my edit page.

When Im submitting my page, (an ascx page), after having filled all the fields, I fill some ModelState.Error (with ModelState.AddModelError) It is well detected by my code line "if (!ModelState.IsValid) "

However, once the Form is updated (once the line "return" of my Edit(post) is call), not any ModelErrorState are display开发者_JAVA百科ed. The same code on a form using a single table is working without any problem.

Im almost sure that the problem is coming from the way I reload my structure.

Any idea ?

Well I finally found my answer.

I was writing the following line : ModelState.AddModelError("MY_DATE_TO_FILL", "Please fill this field");

instead of the following : ModelState.AddModelError("MyClass.MY_DATE_TO_FILL", "Please fill this field");

Its working now.
