Current behavior

I’m getting the following error when trying to initialize a component using the taginput. As a result, I’m not getting text change notifications which I need when trying to use the observable source rather than autocompleteitems for other controls as well.

TypeError: this.tagInput.onTextChange.filter is not a function

Expected behavior

I wouldn’t see the error and suggestions would be filtered on keypress.

Minimal reproduction of the problem with instructions (if applicable) I’ve used the following markup for my sample. The model appears to bind and autocompleteitems show.

                    <tag-input name="Race" 
                               [(ngModel)]="model.Victim.Race" 
                               [onlyFromAutocomplete]="true"
                               [placeholder]="'Select all that apply'"
                               >
                        <tag-input-dropdown 
                               [autocompleteItems]="model.RacesValues"
                               [showDropdownIfEmpty]="true"
                               [displayBy]="'Value'"
                               [identifyBy]="'Value'"></tag-input-dropdown>
                    </tag-input>

What is the motivation / use case for changing the behavior? (if applicable)

What do you use to build your app? (SystemJS, Webpack, angular-cli, etc.). Please specify the version SystemJS - ^0.20.14

Angular version: 4.2.4

ng2-tag-input version: ngx-chips: ^1.4.5-beta

The error I got was: this.tagInput.onTextChange.debounceTime is not a function

In case others find this issue - your angular component file where you declare an @Component MUST have these two lines in the import section

import ‘rxjs/add/operator/filter’; import ‘rxjs/add/operator/debounceTime’;

Let’s make it 3 (I think) if you have dropdown too, but why?

import ‘rxjs/add/operator/filter’; import ‘rxjs/add/operator/debounceTime’; import ‘rxjs/add/operator/map’;
