Going through the code in the RunUpdateRequestProcessor we call at one
point :
…
Document luceneDocument = cmd.getLuceneDocument();
// SolrCore.verbose("updateDocument",updateTerm,luceneDocument,writer);
writer.updateDocument(updateTerm, luceneDocument);
..
Inside that method we call :
public Document getLuceneDocument() {
return DocumentBuilder.toDocument(getSolrInputDocument(), req.getSchema());
}
Then exploring the toDocument we find what we need :
org/apache/solr/update/DocumentBuilder.java:114
And looking into there we realise it is a bug :
…
if (!destinationField.multiValued() && destHasValues) {
throw new SolrException(SolrException.ErrorCode.BAD_REQUEST,
"ERROR: "+getID(doc, schema)+"multiple values encountered
for non multiValued copy field " +
destinationField.getName() + ": " + v);
}
...
Because the check is actually checking in already used fields, not
expecting the copy field to be already valorised.
Hence the exception coming.
I will create an issue for that and provide a patch as soon as I have
time ( or anyone can provide the patch).
Cheers
