Subject Deduplication patch not working in nightly build
Date Mon, 05 Jan 2009 09:06:29 GMT

Hey there,
I was using the Deduplication patch with Solr 1.3 release and everything was
working perfectly. Now I upgraded to a nigthly build (20th december) to be
able to use new facet algorithm and other stuff and DeDuplication is not
working any more. I have followed exactly the same steps to apply the patch
to the source code. I am geting this error:

Mark do you know if I should to some extra hack to run DeDuplication patch
in the new solr version (nightly)? Has something changed in the source that
make it not work or it's simply that i am doing something wrong?

Thanks in advanced
