Exception during facet.range of id org.apache.solr.common.SolrException: Unable to range facet on field:id{type=string,properties=indexed,stored,omitNorms,omitTermFreqAndPositions,sortMissingLast,required, required=true}

This is the error I'm encountering when i try to do a facet range over ID field of my document. What am I doing wrong here in terms of defining this field in the schema? Have i violated any rules for eligibility for facet range query?

If you're using the facet.range option (new in Solr 3.1), the docs say "one can use the Range Faceting feature on any date field or any numeric field that supports range queries" but your field type is a string.
