Canceling form edition but not triggering form validators

Yes,

You have to use immediate attribute of the commandButton.

Quote:

The immediate attribute is a boolean flag indicating that component events should be sent to registered event listeners immediately rather than after the validation phase of the JSF request processing lifecycle. The immediate flag allows you bypass JSF validation for a particular component.
