hello, I have several portlets, and several user groups. now I want to hide the portlet for some groups, and show it to some others. I found this site: http://64.233.179.104/search?q=cache:y8smCcbQ9TAJ:zope.groupsense.co.nz/grou psense.co.nz/zwiki/PersonalisingAccess+tal:condition+group&hl=nl&gl=be&ct=cl nk&cd=4 so I tried: <html xmlns:tal="http://xml.zope.org/namespaces/tal" xmlns:metal="http://xml.zope.org/namespaces/metal" i18n:domain="plone"> <body> <div metal:define-macro="portlet"> <div class="portlet" id="portlet-partners" tal:condition="python: 'partners' in user.getGroups()"> ... but it doesn't work. now, when I log in as a member of the 'partners' group, the portlet doesn't show, when I log in as a member of another group, it doesn't show either, and when I look at the site as an anonymous user, ... I get an error, thanks in advance, Olivier here's the traceback: Site Error An error was encountered while publishing this resource. AttributeError Sorry, a site error occurred.
