Bug report

The addCard command, called from a TaskBoard in the PreviewPane, is also executing for the parent TaskBoard. That results in a JS error.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/ayUsOwel/6
2. Open the Preview Pane.
3. Try adding a Card in the TaskBoard in the Preview Pane.

Current behavior

A JS error is thrown and a card is not created.

Expected/desired behavior

No JS errors should be thrown and the card should be created.
