Thanks Jorg for your help...
Just run that line you asked for....

I just tried the IS references mode, not exactly sure what I was doing, but
seemed to generate the xml with ids instead of the xpath's so guess it worked ok
xStream.setMode(XStream.ID_REFERENCES);
xStream.aliasSystemAttribute("xstreamId", "xstreamId");
Still have the same issue though, stripping out the <id>'s freezes for
fromXml() still :o(
Any other suggestions?, I'm going to have a look through the xstream
documentation to try get a better understanding of whats going on, I'm
wondering if I can write a custom converter to strip out id values, all objects
with the id extend AbstractEntity so maybe I can do something with that.
Thanks

If the TreeSetConverter can use its optimized mode, then the compareTo is not
called, but I cannot know without knowing Java version and vendor. For your
environment it should work without.

For ID mode you have to set a system alias for "id", because you have members
of this name on your own. At least it will strip down the long references at
the end of your file to a plain number.
