[xwiki-users] Deleting spaces

Hi all, I'm trying to use the delete space code snippet I found on the xwiki.org website. I got a Null Pointer Exception when deleting pages (even if I have administrator rights on the wiki). If I use other function on the documents (as, rename for example) they work fine. Here is the code for the panel: #panelheader('Spaces') #if($request.space) #if($request.confirm=="1") #foreach($item in $xwiki.getSpaceDocsName($request.space)) $xwiki.getDocument("${request.space}.${item}").delete() #end #else [Confirm delete space ${request.space}>$doc.fullName?space=${request.space}&confirm=1] <br>List of docs that will be deleted #foreach($item in $xwiki.getSpaceDocsName($request.space)) * $item #end #end #else #foreach($space in $xwiki.spaces) $space \[[Delete>$doc.fullName?space=${space}]\]<br/> #end #end #panelfooter() I have also used the function checkAccess("delete"), and it returns true, so I'm sure that I have right to delete the document. Any idea of what's going on? Thanks! Vito
