Vasili Logvinov commented on SOLR-9477:
---------------------------------------

I found workaround for myself.
 <dataConfig>
 *<script><![CDATA[function +GenerateId+(row) {row.put('+id+', java.util.UUID.randomUUID().toString());return row;}]]></script>*
 <document>
 <entity name="parent" pk="id" query=".......">
 <entity name="child" pk="+id+" child="true" query="......." *transformer="script:+GenerateId+"*>
 </entity>
 </entity>
 </document>
 </dataConfig>

> UpdateRequestProcessors completely ignore child documents. The only exception is AddSchemaFieldsUpdateProcessorFactory. The rest seem to be completely unaware that SolrInputDocument has getChildDocuments() or related methods.
> Easy test (on Solr 6.2):
> This works (with IDs auto-assigned and field names generated):
> {code}
> bin/solr create -c childtest
> bin/post -c childtest -type application/json -format solr -d '[{"a":1,"b":2}]'
> {code}
> This fails as the second/third command, with "missing ID field":
> {code}
> bin/post -c childtest -type application/json -format solr -d '[{"a":1,"b":2,"_childDocuments_":[{"c":3,"d":4}]}]'
> {code}
> The message:

> I also verified it with BlankRemoving URP. I think this is a global problem.
