Any steps to reproduce? from initial evaluation, the problem lies in the fact that the IDOMModel's Document returns null in the getDocumentElement() method. For your particular document at the particular point in time. The null value is currently not handled and I would rather not include such check (which would render the whole editing operation a noop) without an understanding of the condition that arose here..
Sorry. I don't have any step's to reproduce this.
@Milos do you still plan to work on this for Juno M5 (which is next week, Friday, February 03, 2012)?
Removing target milestone. I assume 'Juno M5' milestone was set by accident.
Closing old/stale bugreports.
