Re: [jira] [Created] (SOLR-2737) I get ClassCastException when

Posted by Erick Erickson <er...@gmail.com>.
The way this usually works is that one of the committers
needs to pick this patch up and commit it to the repository.
To facilitate that, could you please attach the patch file
to the JIRA? There should be a "more actions" and
"attach file".
And if you could, please call the file SOLR-2737.patch
Here is the web page for reference:
http://wiki.apache.org/solr/HowToContribute#Generating_a_patch
Thanks much for doing this work!
Best
