Of course I checked:

1) Add a document in eXist

2005-12-07 19:15:32,277 [P1-8] DEBUG (Collection.java [setupTriggers]:103=
4) - Using trigger: exist.CacheEventTrigger
2005-12-07 19:15:33,793 [P1-8] DEBUG (Collection.java [setupTriggers]:103=
4) - Using trigger: exist.CacheEventTrigger

2) Restart eXist

3) Add another document in eXist, you get:

4) cadaver http://myhost/exist/webdav/db/system/config/db/some/other/path
   edit collection.xconf

5) Replace collection.xconf with a clean copy by issuing =AB=A0put
collection.xconf=A0=BB in cadaver

6) Add a document in eXist, it works!

***************************************************************
In fact, collection.xconf gets corrupt when exist is restarted!

AFAICT this test uses IndexQueryService to configure the
collection.  It does not store a document named
=AB=A0collection.xconf=A0=BB into /db/system/config/db.

Thanks in advance for your help,
