AngularJS orderBy does not work with track by in ngOptions?

Answer 1

In order to use tracking with filters, the track by expression needs to be added after the filter.

Try this instead:

user.id as user.name for user in users | orderBy: 'name' track by user.id

The documentation for ngRepeat mentions this under the "Arguments" section, specifically:

Filters should be applied to the expression, before specifying a tracking expression.

and

For example: item in items | filter:searchText track by item.id is a pattern that might be used to apply a filter to items in conjunction with a tracking expression.
