I'm working on a project which involves a whole bunch of different mvc widgets. Most of these have used custom designers added with Thunder, but one of them required some extra functionality which I did with a feather-type designer instead. Ever since then, any time I try to add a designer to an existing mvc widget using thunder, the wizard is never able to see my widgets. I've built the project, even added the widget to a page already, but the designer wizard still refuses to see my widget as one which can have a designer added to it. I've worked around this so far by copying the designer files from an older widget and updating them to work with the new widget, but it's a tedious process.
Another oddity is that if I create a widget and do not create a designer for it, when I click on the edit link after adding it to a page, the designer which shows up is a feather designer. I'm not sure what that means, since the widget should not have any designer at all, and should just get the default advanced one.
I'd appreciate any help anyone can give as far as figuring out how to make my new mvc widgets show up in the thunder wizard for adding designers to existing mvc widgets.
