Topic: Problem using mdb-select with filterEnabled

miki pro asked 6 years ago

I have problem using mdb-select with [filterEnabled]="true". When I fill first input field and move to select field I am getting error:  ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value: 'ng-untouched: true'. Current value: 'ng-untouched: false' I am using "ng-uikit-pro-standard@6.2.5" version.

Solved in 6.2.6 version!

This appears to be still broken (or broken again) in 7.2.0.

Arkadiusz Idzikowski staff commented 6 years ago

Thank you for letting us know about this problem. There were many changes in select change detection since version 6, we will check if any of them can cause this error.
