I've run into infinite event loops a few times tonight, but this one is particularly strange

I have a listview and I want to call into some of my systems when it changes

but then calling my other code creates an infinite cycle, apparently, even though as far as I can tell that code is pretty ui independent

Aha I shouldn't have posted here, you don't know how my systems are arranged lol

Feels like potentially a bug maybe? I get this error as soon as the UI loads

Okay so I think the loop is because I have `editor` in `AssetBrowser`, I call `editor.setSelectedAsset` which changes the (private) field `editor.selectedAsset`, as a field in `editor` has been changed, and `AssetBrowser` has the `editor` field, `onChange` is triggered and it loops. Whew.

Bypassing `setSelectedAsset` and just changing the (now public) field directly causes the same issue, this feels buggy

any chance of a minimal test case? Hard to fully understand by just reading the above 🙂

Ah yep I'll try and whip something together

"TEST" isn't printing when I hit the button... have I forgotten something basic for the testcase?

Ah, very unfortunate, the test case still works 😆

Logs fine. Hmmm. Can't spot structural difference. There are differences, obviously - button instead of listview, organisation of classes, etc, but I thought I recreated cycle 🤔

Aha, in _my_ code if I use a button and `CLICK` the issue doesn't happen, I'm guessing now it's something `CHANGE` related

That works 😠 Why won't this code break lol

Aha oh my gosh okay check this out for a finding! This is why I try to run far, far away from macros and other dark magic

and whats the error? I mean, how does that cause an invalidation loop?

Same as before I think https://cdn.discordapp.com/attachments/565569107701923852/728213540208377856/unknown.png
