When you have to change the columns dynamically and apply this.grid.allowFiltering = true/false an error is thrown:

  • igniteui-angular version: 7.1.1
  • browser: all

Steps to reproduce

Open this sample in StackBlitz.
The sample contains a button that changes the columns and toggles the filtering.
Click on the button


An error is thrown:
ERROR Error: Cannot read property 'filteringExpressionsTree' of undefined

Expected result

It should not throw errors.
