I allways build solr index from scratch, so I don't have neither "pk"
attribute in "entity" tag (dataconfig.xml file) nor "UniqueKey" in index
schema. When I updated solr from 1.3 to 1.4 I got the following exception
during solr initialization:

Is "UniqueKey" in schema still optional in solr 1.4? Is "pk" attribute in
still optional in solr 1.4 DataImportHandler entities? As I can see in
org.apache.solr.handler.dataimport.DataImporter class source exception
allways occure when UniqueKey not specified for index schema.
