Current behavior

I’m getting error:

this.inputForm.onBlur.filter is not a function
    at TagInputComponent.setUpOnBlurSubscriber

My code looks more or less like this

<tag-input
            [(ngModel)]="data.types"
            [onTextChangeDebounce]="200"
            [onlyFromAutocomplete]="true"
            [clearOnBlur]="true"
            [removable]="mode === 'add' || mode === 'update'"
            [disabled]="mode === 'view' ? true : null"
            (onAdd)="updateServiceInput()"
            secondaryPlaceholder="+"
            placeholder="+">
            <tag-input-dropdown
              displayBy="name"
              identifyBy="name"
              [autocompleteObservable]="indicatorTypesSuggestion">
              <ng-template let-item="item" let-index="index">
                {{ item.name }}
              </ng-template>
            </tag-input-dropdown>
          </tag-input>

And afterwards, upon selecting an item from the suggestion, I received:

ERROR Error: Unable to process animations due to the following failed trigger transitions
@animation has failed due to:
- Please provide a value for the animation param enter
- The provided timing value "" is invalid.

Expected behavior

No error shouldn’t be thrown.

Minimal reproduction of the problem with instructions (if applicable)

as described above.

Found out that this was caused by not importing the rxjs filter. Adding the following to my module fixed the issue:

import 'rxjs/add/operator/filter';

Mine was an example but you can use whatever you want with the observable as it is done in your parent component 😃
