No, I had not. I just tested and the super implementation of it does return false in my classes, but I overrode it in any case just to make sure I do not get bit by it the underlying implementation changes down stream. Good idea, I was very hopeful when I first read your email; this is just the type of detail that I expect I have overlooked in my ignorance. - joel > http://dom4j.org/xref/org/dom4j/tree/AbstractNode.html#93 > > Many of the createCopy() methods seem to depend on clone(), so this > might be your problem. > > christian. > > On Jun 8, 2004, at 12:46 PM, Joel Rosi-Schwartz wrote: > > On Tuesday 08 June 2004 17:19, Christian Niles wrote: > >> Hi Joel, > >> > >> I may have to code my own DocumentFactory as well in the near future, > >> so I'm interested in your problem, but don't have an answer for you. > >> > >> Can you tell us which interfaces you've implemented yourself, such as > >> Element, Document, etc?
