In Kendo UI for Angular 2 we have a custom filter (very similar to your provided example http://www.telerik.com/kendo-angular-ui/components/grid/filtering/reusable-filter/#toc-reusable-custom-filter-components), it works nicely, but we get a compilation warning:
export 'CompositeFilterDescriptor' was not found in '@progress/kendo-data-query'
Additionally would it not make sense to extend the base class BaseFilterCellComponent with properties
@Input() public column: ColumnComponent;
@Input() public filter: CompositeFilterDescriptor;
as they are needed by all filters (also seen in your example in dropdownlist-filter.component.ts). so custom filter implementors dont need to add them. Decorators on properties are inherited now in Angular/typescript

We received several reports about this issue, but we suspect that the warning is caused by the followingAngular/CLI and Webpack issue:
https://github.com/angular/angular-cli/issues/2034
We believe that until the issue gets fixed on their side, you can safely ignore the warning, and use the discussed interface.
Thank you BaseFilterCellComponent extending suggestion. We will explore the opportunities, enabled by the enhancements, provided by Angular, allowing decorators inheritance, but in general we are cautious when it comes to introducing updates that may lead to breaking changes in existing applications.

The warning will be removed by using this code:
import * as [InsertNameHere] from '@progress/kendo-data-query';
Then I use it like this: [InsertNameHere].CompositeFilterDescriptor
Thank you very much for sharing this workaround with the community.
It is indeed a straight-forward approach to remove the innocuous but still undesired warning.
