元素没有“Serenity.EnumEditor”类型的小部件！

Question

I'm building an application for Student Information System using serenity platform. In the dashboard I've one widget showing number of active students, when click on "More info" I want to display only the active students, I got the below error: "Element has no widget of type 'Serenity.EnumEditor'!"

I've followed the same steps as the Northwind order example but no success:

protected ESTS_CODEFilter: Serenity.EnumEditor;

 protected createQuickFilters(): void {
            super.createQuickFilters();
            let fld = Students.EnrollmentRow.Fields;
            this.ESTS_CODEFilter = this.findQuickFilter(Serenity.EnumEditor, fld.ESTS_CODE);
        }

public set_ESTS_CODE(value: string): void {
            this.ESTS_CODEFilter.value = value == null ? '' : value;
        }

In the StudentsIndex.cshtml page I've the below code to get the query string:

<script type="text/javascript">
    jQuery(function () {
        var EnrollGrid = new Portal.Students.EnrollmentGrid($('#GridDiv'), {});

        var q = Q.parseQueryString();
        console.log(q.ESTS_CODE);
        if (q.ESTS_CODE != null && q.ESTS_CODE.length) {

            EnrollGrid.set_ESTS_CODE(q.ESTS_CODE);
        }
        Q.initFullHeightGridPage($('#GridDiv'));
    });

</script>

Any idea how to define a widget of type Serenity.EnumEditor?

Thanks

Are you sure you have a EnumEditor there? Not a LookupEditor?

protected createQuickFilters(): void {
            super.createQuickFilters();
            let fld = Students.EnrollmentRow.Fields;

            this.ESTS_CODEFilter = this.findQuickFilter(Serenity.LookupEditor, fld.ESTS_CODE);
        }
