[GeoNetwork-users] Error when using GAST for metadata export

hello,

I'm trying to use GAST to export metadata from a GeoNetwork
2.1installation. The installation uses Jetty and McKoi. There is quite
a lot of
metadata, mostly obtained through harvesting. When trying to export, GAST
displays an error message like this :

Error from server:
<error id="metadata-not-found">
<message>Metadata not found</message>
<class>MetadataNotFoundEx</class>
<stack>
<at class="org.fao.geonet.services.mef.Export" file="Export.java" line="66"
method="exec">

.. etc.

Has anyone seen this too ?

regards,
Heikki Doeleman
