NullPointerException creating wildcard index

I would like to create an index for all foo attributes within my
collection. According to the documentation I specified *@foo as the index
pattern. However the database server throws NullPointerExceptions for all
documents within the collection during indexing. The exception looks like:

DEBUG> java.lang.NullPointerException
	at org.apache.xindice.core.indexer.IndexPattern.getMatchLevel(Unknown Source)
	at org.apache.xindice.core.indexer.IndexManager$SAXHandler.processEntry(Unknown Source)
	at org.apache.xindice.core.indexer.IndexManager$SAXHandler.endElement(Unknown Source)
	at org.apache.xindice.xml.sax.SAXEventGenerator.processContainer(Unknown Source)
	at org.apache.xindice.xml.sax.SAXEventGenerator.processContainer(Unknown Source)
	at org.apache.xindice.xml.sax.SAXEventGenerator.processDocument(Unknown Source)
	at org.apache.xindice.xml.sax.SAXEventGenerator.start(Unknown Source)
	at org.apache.xindice.core.indexer.IndexManager$SAXHandler.<init>(Unknown Source)
	at org.apache.xindice.core.indexer.IndexManager.populateNewIndexers(Unknown Source)
	at org.apache.xindice.core.indexer.IndexManager.access$300(Unknown Source)
	at org.apache.xindice.core.indexer.IndexManager$AutoIndexer.run(Unknown Source)

You can easily reproduce this problem:
 1. add a collection testcoll to db
 2. add a simple document (e.g. <test>text</test>) to /db/testcoll
 3. add index with pattern *@foo to /db/testcoll

I got this with Xindice RC1 running on Solaris and on Windows 2000.


Any help would be appreciated.

I'll try to get this fixed this evening.  It's probably something 
simple, and the result of stupidity. :)
