Description Peter Zavadsky 2008-07-08 12:59:33 UTC

When trying to capture the events (according the example), and convert the target to DOM nodes, this exception is
produced. Also when I tried to put entire source into Moz async call, or switch off editing itself it didn't help.

Comment 1 ceresna 2008-07-25 18:10:50 UTC

fixed rev 93066:d4795f140d35

The problem was when casting currentTarget from nsIDOMEventTarget to nsIDOMNode.
The event target was a nsIDOMWindow and not a nsIDOMNode, so an exception
was thrown. Fixed to return null instead.
