Subject RE: [future-showstopper] Sitemap reload & dispose() & NPEs
Date Wed, 20 Mar 2002 13:40:48 GMT
This could be something introduced by the code that Leif added
to order the disposal of components.

Still, this does not come into affect until the items are actually
disposed.

Could you send an offending log?  It might help to determine what
is going on.

Question:

Does it happen when you use the TreeProcessor?
