Solr unique key can't be blank

Consider this simple schema:

<?xml version="1.0" encoding="UTF-8"?>
<schema name="uuidTest" version="0.1">
	<types>
		<fieldType name="uuid" class="solr.UUIDField" indexed="true" />
	</types>
	<fields>
		<field name="id" type="uuid" indexed="true" stored="true" required="true"/>
	</fields>
</schema>

When trying to upload it to Websolr I am getting this error:
Solr unique key can't be blank

I also tried adding this element to the XML, after </fields>:
<uniqueKey>id</uniqueKey>

However this did not help. What could be the issue? I The code is
taken verbatim from this page:
http://wiki.apache.org/solr/UniqueKey

Note that this is on a Solr 4 Alpha index. Thanks.

The UniqueKey wiki was recently updated to indicate this new Solr 4.0 
requirement:

http://wiki.apache.org/solr/UniqueKey

"in Solr 4, this field must be populated via 
solr.UUIDUpdateProcessorFactory"

The changes you were given are contained on that updated wiki page.

Thank you Ahmet! In fact, I did not know that the
updateRequestProcessorChain needed to be defined in solrconfig.xml and
I had tried to define it in schema.xml. I don't have access to
solrconfig.xml (I am using Websolr) but I will contact them about
adding it.

Thank you.

Please not that you need to reference it to UpdateRequestHander that you are using. (this can be extracting, dataimport etc)

  <requestHandler name="/update" class="solr.UpdateRequestHandler">
    <!-- See below for information on defining 
         updateRequestProcessorChains that can be used by name 
         on each Update Request
      -->
    
       <lst name="defaults">
         <str name="update.chain">uuid</str>
       </lst>       
  </requestHandler>

Hi Dotan,

Did you define the following update processor chain in solrconfig.xml ?
And did you reference it in an update handler?
 
<updateRequestProcessorChain name="uuid">
    <processor class="solr.UUIDUpdateProcessorFactory">
      <str name="fieldName">id</str>
    </processor>
    <processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
