NullPointerException when using escapeSql function
--------------------------------------------------
Key: SOLR-2141
URL: https://issues.apache.org/jira/browse/SOLR-2141
Project: Solr
Issue Type: Bug
Components: contrib - DataImportHandler
Affects Versions: 1.4.1
Environment: openjdk 1.6.0 b12
Reporter: Edward Rudd
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).
