IDE Bug? Enable Packages FAIL

What I’m trying to do:
Upgrade an old, existing App to use Packages. Not Python 3, just Packages. (One step at a time.)

What I’ve tried and what’s not working:

  1. Start IDE
  2. Gear → Upgrade to Python 3… → Yes
  3. Save this version
  4. Close or run app

The IDE reports that the App has not been saved, and that any recent changes may have been lost. Sure enough, “View history” does not show the saved change.

With various editor backup folders and WinMerge backup files, in my local working directory, it’s hard to be sure exactly how big this app is, but it was well over a megabyte (and over 200 files) a year ago.

I’ve tried with Chrome (private mode), Edge, and Firefox. Same result each time. No harm done, but no new folder structure, either. Near as I can tell, everything’s just as it was.

Task Manager does not indicate that the IDE ran out of memory.

If need be, I can send a clone link privately.

I tried again, this time through a different set of GUI steps:

  1. Start IDE
  2. Explicitly Save current state of application.
  3. Navigate to Server Modules.
  4. Pick the last Server Module.
  5. In its dropdown menu, choose Enable Packages.
  6. Wait a few seconds.
  7. Save the new state of the app.
  8. Close the IDE (return to “Create an app”)

After a minute or so, the browser complained that the App was not saved. I was prompted to reload it. The IDE showed that, contrary to the warning, it had been saved, and I now had SERVER CODE et al in the App Browser.

In fact, the App was able to run, with no further changes on my part.

The IDE is now more able to catch goofs, like missing event-handlers.

So far, the update is successful in my Development app. Once I duplicate this in Production, I can call this a success.

Edit: Tried the same thing with Production. Seems to be working.
