Subject: Re: DataImport Handler, writing a new EntityProcessor

Hi!

Thanks for all the advice! I finally did it, the most annoying error
that took me the best of a day to figure out was that the state
variable here had to be reset:
https://bitbucket.org/dermotte/liresolr/src/d27878a71c63842cb72b84162b599d99c4408965/src/main/java/net/semanticmetadata/lire/solr/LireEntityProcessor.java?at=master#cl-56

The EntityProcessor is part of this image search plugin if anyone is
interested: https://bitbucket.org/dermotte/liresolr/

:) It's always the small things that are hard to find

cheers and thanks, Mathias
