[xwiki-users] Is there a permanent ID of xwiki doc?

I notice that the value of ID of the xwiki doc changed after I renamed the doc to another Space. For some reasons, I'd like get the same doc use a unchanged, unique value, can I do that with XWiki? -- ----------------------------------------------------------------------------------------- 空中的一小块陆地 E-mail : [email protected] Blog : http://flyisland.blogbus.com/ Twitter : http://twitter.com/flyisland -----------------------------------------------------------------------------------------
