                 Key: SOLR-2463
                 URL: https://issues.apache.org/jira/browse/SOLR-2463
             Project: Solr
          Issue Type: Bug

When using an Evaluator outside an entity element the Context argument is null.

public class LowerCaseFunctionEvaluator extends Evaluator {
 public String evaluate(String expression, Context context) {
   List l = EvaluatorBag.parseParams(expression, context.getVariableResolver());
   if (l.size() != 1) {
     throw new RuntimeException("'toLowerCase' must have only one parameter ");
   }

   return l.get(0).toString().toLowerCase();
 }
}

<dataSource   name="..."
              type="..."
              driver="..."
              url="..."
              user="${dataimporter.functions.toLowerCase('THIS_WILL_NOT_WORK')}"
              password="..."
              batchSize="..."/>


 <entity name="..."
            dataSource="..."
            query="select * from 
${dataimporter.functions.toLowerCase('THIS_WILL_WORK')}"
