losing this.selection.selected

[tatsujb]

Bug, feature request, or proposal:

request

What is the expected behavior?

can filter, search select and filter by selection

What is the current behavior?

filter deletes selection

What are the steps to reproduce?

https://github.com/angular/material2/blob/master/src/material-examples/table-selection/table-selection-example.html

over here you provide and example for how to select in a mat-table.

there we discover cdk's or your own invention : this.selection.selected.

I find it very useful. and I want to keep using it.

but I can't work out how to combine it with filters and so on.

I have an ion range slider (http://ionden.com/a/plugins/ion.rangeSlider/en.html & packaged for angular : https://github.com/PhilippStein/ng2-ion-range-slider) to select the visible range, not material's page selector.

I set the dataset.data to a sliced version of the array (maybe that's not what I should be doing maybe I'm missing something here, like using a pipe instead).

and the step before, the function that calls the slicing function, is the filtering function which sends the filtered result to the slice function to have it be sliced.

I suspect that I loose the selection data in the process of setting this new value for the dataset.

how can I avoid this?

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Angular 5.2.8 Material 5.2.4 Windows 10 pro Typescript 2.7.0
