[Exist-open] Saving into webDAV from XXE

[klaus e. w. <kew...@fa...>]

Dear eXist users,

on loading and on saving a file from a webDAV collection using XMLMind's XXE 
Editor I get always the following message:

Cannot check whether the file
"http://localhost:8080/exist/webdav/test/docbook.xml"
has been locked or not:
invalid response '<?xml version="1.0" encoding="UTF-8"?>
<D:multistatus xmlns:D="DAV:">
 <D:response>
  <D:href>/exist/webdav/test/docbook.xml</D:href>
   <D:propstat>
    <D:prop>
     <D:resourcetype/>
     <D:supportedlock>
      <D:lockentry>
       <D:lockscope>
        <D:exclusive/>
       </D:lockscope>
       <D:locktype>
        <D:write/>
       </D:locktype>
      </lockentry>
     </D:supportedlock>
    </D:prop>
    <D:status>HTTP/1.1 200 OK</status>
   </D:prppstat>
  </D:response>
 </D:multistatus> 
 
 Whereas loading a file from a webDAV collection works, saving does not work. 
Does anyone know if this is an issue on behalf of XXE, or of eXist, or the 
fault lies somewhere in-between?  Is there something I can do?
 
Using webDAV from jEdit works (most of the time, that is).
 
 Best wishes, and many thanks for any help,
