>          Issue Type: Bug
>      Security Level: Public(Default Security Level. Issues are Public) 
>          Components: Server, UpdateRequestProcessors
>    Affects Versions: 6.6.2
>         Environment: EmbeddedSolrServer, HttpSolrClient when using RequestWriter instead of BinaryRequestWriter
>            Reporter: Thomas Wöckinger
>            Priority: Major

> If XMLLoader is used to build SolrInputDocuments Enum values are treated as String values and not as EnumFieldValue like it is done by the binary codec.
> So the doRemove call of AtomicUpdateDocumentMerger will get String values which does not match any EnumFieldValue from the existingField values.
> The behaviour can be tested easily with  the EmbeddedSolrServer because it uses the XML codec to convert the SolrRequest.
> Just create a multivalued EnumField add some values and try to remove some with
> atomic update calls.
> The values will remain unchanged.
