What does "store" mean? In principle, Zope supports various notions of "storing": * store in REQUEST ("REQUEST.set(name,value)") The stored value is available ("REQUEST[name)") during the current request. * store in session ("REQUEST['SESSION'].set(name,value)") The stored value is available ("REQUEST['SESSION][name]") while this session is open. * store persistently as property of an object ("object.manage_addProperty(name,type,value)" (parameter order might be wrong -- check the API reference!)) The stored value is available ("object.getProperty(name)") until explicitly changed/remove. -- Dieter
