I downloaded a newer version of Sencha Architect and let it upgrade both the Sencha Architect/CMD versions associated with my app and also from ExtJs 5.0 to ExtJs 5.1. After doing this I can deploy the application fine, it looks ok, but the designer view in sencha architect doesn't show any of the application. Even if I drag a new form out it just shows an empty canvas. If I click on the Code it shows up ok. Is this something I can fix easily?
