I'm having some strange issues with access rights on http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/Cases/
Issue 1 ====== I configured the space to permit view for unauthorized users. Yet when loggen out I get: Error number 4001 in 4: Error while parsing velocity page Cases.WebHome Wrapped Exception: Failed to evaluate content with id <http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/Cases/>Web Home<http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/Cases/> the root exception seems to be: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'formatDate' in class com.xpn.xwiki.api.XWiki threw exception java.lang.NullPointerException @ Cases.WebHome74,17?

In my desperation, I added this to the class sheet: ## set rights to allow creator and contributors to edit ## THIS DOESN'T WORK: CHICKEN & EGG PROBLEM => TURNED OFF SAVE #macro(allowEdit $user) #set ($rights = $doc.getObject("XWiki.XWikiRights", true)) #set ($result = $rights.set("levels", "edit")) #set ($result = $rights.set("users", $user)) #set ($result = $rights.set("allow", 1)) ## $doc.save() #end #allowEdit($doc.getCreator()) #foreach($contributor in $doc.getObject("Cases.CaseClass").contributors) #allowEdit($contributor) #end but as you can see in the comment, it fails because if a user doesn't have edit rights to begin with, save fails. -- ___________________________ Yishay Mor, Researcher, London Knowledge Lab http://www.lkl.ac.uk/people/mor.html http://yishaym.wordpress.com https://www.linkedin.com/in/yishaymor http://www.google.com/calendar/embed?src=yishaym%40gmail.com +44-20-78378888 x5737
