Upgraded Sencha Architect -- App now blank white screen

[lylepratt]

I just updated Sencha Architect and now my app just shows a blank white screen and doesn't seem to call the "launch" function.

Has anyone else experienced this?

I realize that this post is scarce on the details, but I'm not sure what other information I can provide. I had a perfectly working project, and after upgrading Sencha Architect, nothing loads.

It looks like the app "launch" function is never getting called. Why would that be happening?

Open your app in the browser and use the browsers console (developer tools) to see if you have an JS error.

Turns out it was a few things:

1) The new Architect has debugging turned off by default. I needed to turn it back on.
2) My class Overrides were not migrated properly during the upgrade, so (now visible) errors were getting thrown about colliding requires.
3) New Sencha versions were introduced that were also not migrated in my app.html file.
4) Some very odd issue (still unresolved) with "Ext.setup has already been called".
