Hello Andy, As far as I know, Documents don't have GUID's but object GUIDs are just java.util.UUID.randomUUID().toString(); nothing fancy. If you want new GUIDs for the objects then just copy the blog document, the copy will have different ones. Also I think the reason why velocity is favored here is because groovy has a security bug which allows groovy code to take over the jvm. http://jira.codehaus.org/browse/GROOVY-1875 I hope they get this fixed soon because I think groovy is cool as well.

Hi

To develop the GBlog application I just took the XML from the Blog application and replace its content with mine. So far so good. But lately I see problems with Panels and I am not quite sure if this is related to duplicate GUID in the Panels Document or Object. So I have a few questions:

1) Where and by what is the GUID used?

2) How can I create GUIDs inside or outside of XWiki?

Cheers - Andy
