Subject Re: [vfs] webdav problem

Sorry for taking so long to reply.  I'm a bit confused as the XML response below contains <D:collection/>
which, IIRC, is the indicator being checked for to indicate it is a folder.  I can't see why
that would turn into an ArrayList.  Can you provide the stack trace for the ClassCastException?

If Alfresco is returning a Collection for this property then I'm guessing it will return Collections
for all of them, which is also going to cause problems.

I think I'm going to have to download Alfresco and try it.  

Ralph
