Removing a node of the normalized collection throws exception

[blommish]

The following code is almost a copy of the one generated on the firebase-util site. The problem occurs when I delete one of the nodes in channels in the firebase dashboard, or deleting it by taking channels..child('/child').remove(), it throws the following error.

var channels = baseRef.child("/channels");
var ref = new Firebase.util.NormalizedCollection(
  [channels, "channel"],
  [baseRef.child("/users"), "user", "channel.createdBy"]
  )
.select(
  "channel.createdBy",
  {"key":"channel.name","alias":"channelName"},
  "user.name"
  )
.ref();

Thanks for taking the time to submit this. If I could borrow just a bit more of your time, can you generate a minimal repro that we can use to see this problem happen? Also, seeing the stack trace against the non-minified version would go a long way here. Cheers.

Hmm, made a jsfiddle similar to my case but it does not throw any exception. https://jsfiddle.net/1avmt71y/

So either you close the issue, and I investigate some further. Or you keep it open for a while.

For simplicity, let's close it. If you get a repro, post it here and let's reopen. Feel free to post any questions, clues, or comments you have as you work on it; glad to help.

@blommish did you find a solution for your problem? I am running into the same issue here.

@laurensnl I did not find any solution and due to some other limitations I decided to use the firebase library, even without angular library
