attachHeader w/ filters and event handlers?

Have there been any issues with attachFilter and event handlers?

When I use attachHeader with various filters, the this reference of my event handlers refer to the dhxGrid for some reason. But if I don’t use attachHeader, the this reference refers to the correct object. Is there any reason why attachHeader with filters would cause this problem? Not sure what it does with event handlers…

Unfortunately we cannot reproduce this issue locally. Could you please provide any kind of sample where we can reconstruct this issue?
