Hello, Just a start, you would have to fill what is missing, and I don't know if there is an easier way, but ... {{groovy}} def mydoc = xwiki.getDocument('space.classname') mydoc.getRevisions().each() { rev -> println rev def baseprop = mydoc.getDocumentRevision(rev.toString()).getxWikiClass().get('propname').getBasePropertyClass() println prop } {{/groovy}} ... for a class stored in page "space.classname", and checking the property named "propname". This way you could retrieve the baseprop (PropertyClass) of each revision, store the previous one and compare the information you want for any change (check javadoc for com.xpn.xwiki.objects.classes.PropertyClass). You could also compare directly baseprop.toXMLString(), but I'm not sure it's valid (order always the same, etc ...) Once you have found the revision you want, use mydoc.getRevisionInfo(rev.toString()) to access the RevisionInfo object that will give you the author and date you want. Hope this helps, Jeremie 2011/11/13 Eugen Colesnicov <ecolesnicov(a)gmail.com>
