This sounds great and I got some template running for porting my multi-page app to this format! However, I have two callbacks in one of my pages and something weird happens with it. My page renders totally fine, but I get these errors: Attempting to connect a callback Input item to component: "…

@AIMPED @adamschroeder I think I got what was going on. In entities-details.py, the layout function has “entity” as an input variable but it had NO default value. If I set this input as None, for example, the errors are not triggered by the app. So I just changed: def layout(entity=None): …
