I made a small change to my code - commented out an event handler, and now I get the following. How can I get the App.html back again?
Actually, I can see the App.html file in the webapp directory, so I dont understand why this error is occuring.
I had this happen several times yesterday. And the only way I found to fix it was to delete the who project, and pull it again from our git repo. Not the most effecient. so it would be good to learn, understand and fix it properly.
