Description

Below is a snippet of my solrconfig.xml

<updateRequestProcessorChain name="custom-updates" default="true">
        <processor class="solr.RemoveBlankFieldUpdateProcessorFactory">
           <lst name="exclude">
             <str name="fieldRegex">.*_count</str>
           </lst>
         </processor>
        <processor class="solr.UUIDUpdateProcessorFactory">
            <str name="fieldName">id</str>
        </processor>
        <!-- Allows you make counts for multivalued field-->
        <processor class="solr.CloneFieldUpdateProcessorFactory">
            <str name="source">researchpagekeycontentcategorynames</str>
            <str name="dest">key_content_count</str>
        </processor>
        <processor class="solr.CountFieldValuesUpdateProcessorFactory">
            <str name="fieldName">key_content_count</str>
        </processor>
        <processor class="solr.DefaultValueUpdateProcessorFactory">
          <str name="fieldName">key_content_count</str>
          <int name="value">0</int>
        </processor>

Performing an Atomic Update like this causes that key_content_count to be one (1) when the expected value should be zero (0).

To my knowledge setting a value to null should zero out the count, correct?

curl -s 'http://localhost:9080/solr/ndr/update' -H 'Content-type:application/json' -d '[{"content_key":"ICS_100.RPT","researchpagekeycontentcategorynames":{"set":null}}]'

Thanks for looking into this.
