James Dyer updated SOLR-2141:
-----------------------------
Attachment: SOLR-2141.patch
final patch to commit, fixes a locale problem in the unit test.
Dominik, this patch solves the absence of the dih.functions. namespace, so you
can use either "dih." or "dataimport." as before. Also, it solves the related
problem on SOLR-3842. Finally it has a pretty good unit test that demonstrates
this issue, SOLR-3842 and SOLR-4047 (this last one doesn't appear to actually
be broken).

> I have two entities defined, nested in each other..
> <entity name="article" query="select category, subcategory from articles">
> <entity name="other" query="select other from othertable where
> category='${dataimporter.functions.escapeSql(article.category)}'
> AND
> subcategory='${dataimporter.functions.escapeSql(article.subcategory)}'">
> </entity>
> </entity>
> Now, when I run that it bombs on any article where subcategory = '' (it's a
> NOT NULL column so empty string is there) If i do where subcategory!='' in
> the article query it works fine (aside from not pulling in all of the
> articles).
