Re: Restoring NodeTreeMaps

Hi again Thomas,

I'm guessing the bug you posted about previously produced an incomplete 
data file, and the XML parser is choking on that in the stack trace 
below... perhaps try to get your system running again from a recent 
backup (if that's an option), then take a look at the data xml file that 
you're trying to recover from... if you're lucky, any decent XML editor 
tool can be used to validate the XML, which may show error's in the 
file's structure... Then it's up to you to patch up the file manually.

There's probably a better solution, but I'm an Ozone newbie, and I'm 
more interested in the actual code than administration / backup systems...

good luck
