Right now, the way that the save button is disabled when you click it is that MWSaveDialog listens to the button's click event, in response to that it fires the 'save' event, ArticleTarget gets that event, reaches into the save dialog and disables the button.
This is only one of many insane things about the totally dysfunctional MWSaveDialog - ArticleTarget relationship; the whole way these two interact should be refactored.
