hi, how can i validate the new MdbInput control?

[template]
<input mdbInput mdbValidate type="text" class="form-control" id="caseid" name="caseid"
#caseid="ngModel" ngModel)]="currentCaseData.caseid" placeholder="" 
required [validate]="true" [validateSuccess]="false"
[validateError]="true" disabled]="isCaseLocked">
<label for="caseid">Case ID</label>
<mdb-error *ngIf="caseid.invalid && (caseid.dirty || caseid.touched)">Case ID is required!</mdb-error>
[/template]

after declaring a viewchild on the input with

[code]
@ViewChild('caseid', {read: MdbInput}) private caseidField: MdbInput;
[/code]

i try to validate like this: 
[code]
this.caseidField.element.focus();
this.caseidField.element.blur();
//this.caseidField.element.focusBlur();
//this.caseidField.element.markAsTouched();
[/code]

where the last 2 lines cause errors... focus & blur dont - but the validationError does not get shown at all.

if i manually click and make the input lose the focus the error message gets correctly shown! what's the trick to make it work?

## btw, im using the newest version (7.1.1).. which doesnt exist as option in the select ##

Thanks
