Sylvain,

Are these forms part of a formset? You can't mix modal and modeless forms inside a formset, even though it would seem to be a natural use of them to have a modeless parent launch modal child forms but you can't do that.

Are you sure there's no LockScreen issues that are preventing you from seeing the form? I'm curious if you try it with three other forms with no other code anywhere besides the launching code.
