Question

I’m trying display some data loaded from a datastore and it’s not reflecting changes on the UI. I created an example to show a general idea of what I’m trying to achieve.

Here is the link to angularjs example where they show when on click then dropdowns are clear out. If you replace the expression with one of the colors of the list dropdowns are well selected. Does this type of selection only work on user events?

Help is appreciated!!!

Answer 1

Actually the problem is that ngSelect compares objects using simple comparition operator (‘==’), so two objects with same fields and values are considered as different objects.

So you better use strings and numbers as values (‘select’ parameter in expression of ngSelect directive).

Here is kind of solution for your plunker.

Aslo there are some discussion about this topic on GitHub:
https://github.com/angular/angular.js/issues/1302
https://github.com/angular/angular.js/issues/1032

Also as I headred there is some work in progress about adding custom comparor/hashing for ngSelect to be able to use ngSelect more easier on objects.
