Hi I upgraded my project from V7 to V8 tonight and I got a bunch of errors reading the @viewChild which was due to the new updates they did. I added { static: true } to all my @viewChild, but then I came across these triggers that I have setup up like this:
@ViewChild('tTaskTeam', { read: MatAutocompleteTrigger }) autoCompleteForTaskTeamTrigger: MatAutocompleteTrigger;
@ViewChild('tofficeUser', { read: MatAutocompleteTrigger }) officeUsersautoCompleteInputTrigger: MatAutocompleteTrigger;
@ViewChild('recipientType', { read: MatAutocompleteTrigger }) recipientTypeTrigger: MatAutocompleteTrigger;
The viewChild only accepts two parameters and I can't add three. So I took read: MatautocompleteTrigger out and it broke my autocomplete function that I had going.
This is the error message I am getting :
Argument of type '{ read: typeof MatAutocompleteTrigger; }' is not assignable to parameter of type '{ read?: any; static: boolean; }'. Property 'static' is missing in type '{ read: typeof MatAutocompleteTrigger; }' but required in type '{ read?: any; static: boolean; }'.ts(2345) core.d.ts(8066, 9): 'static' is declared here.
I added these triggers to trigger if a user enters characters that aren't from the selected option list. So it will clear out and give the user a message to have them select again.
This is the full implementation: HTML
<mat-form-field appearance="outline" class="task-info-form-field">
<input tab-directive #tTaskTeam matInput (keyup.enter)="chooseFirstOption(autoCompleteForTaskTeam)" [matAutocomplete]="autoCompleteForTaskTeam" formControlName="tTaskTeam" matTooltip="You can search and it will try to autocomplete the name for you!" placeholder="Select Group">
<mat-autocomplete #autoCompleteForTaskTeam='matAutocomplete' [displayWith]="displayTeamName">
<mat-option class="matAutoCompleteSelect" *ngFor="let user of filteredOptions | async" [value]="user">
<span>{{ user.TeamName }}</span>
</mat-option>
</mat-autocomplete>
<mat-error>
Value entered is NOT VALID please selected only from suggested values.
</mat-error>
</mat-form-field>
