[xwiki-users] No document found in the selected archive...

Hi all, I have a problem importing documents from a Xar I exported. I have 3 Xwiki Installations (devel,test, production), all installations are 1.2 release. I tried to export contents from test server to import it into both Devel and Production Servers.

Thanks, Loris
