I have come across an issue with the DIH where I get a null exception when pre-caching entities. I expect my entity to have null values so this is a bit of a roadblock for me. The issue was described more succinctly in this discussion: http://lucene.472066.n3.nabble.com/DataImportHandlerException-when-cache-key-is-null-in-SOLR-1-4-1-td2003059.html
Anyone know anything about this?
