After updating the Plumsail app from 1.0.7.1 to 1.1.0.0, one of our forms that has the List or Library control on it no longer opens in a dialog when clicking the Add New Item button. When you click the button, a dialog starts to load and then redirects to the new item page.
I went ahead and removed/re-added the list control on the form, republished it (confirmed the widget was now showing as 1.1.0), and that seems to have fixed it!
