Jack Krupansky updated SOLR-3502:
---------------------------------
Attachment: SOLR-3502-4x.patch
I can repro the problem in 3.6.
The essence is that the copyField code checks to see if the destination field
has already been set in the output Lucene document, but this doesn't catch the
case where the setting of the destination in the SolrInputDocument occurs after
the setting of the source field.
Patch for 4x branch is attached. Similar patch should be applied to trunk and
3.6.1. Tested for 4x.

> we have two field on both solr:
> <field name="A" type="text" indexed="true" stored="true"/>
> <field name="B" type="string" indexed="true" stored="true"/>
> <copyField source="A" dest="B"/>
> We have a SolrDocument reader (solrj client without pojo binding) that takes
> all docs from one solr and SolrInputDocument write them on the other solr.
> On B field in the target solr we ended with an Array containing the duplicate
> value we have on the first solr. How could solr internally break schema ?
