Hi, I would like to talk about cleaning an initialize issue. I had the problem that Squeak Changesets don't sort the initialize messages of some classes in the right order and it happend that after init the subclasses of Structure, the later init of Structure itself destroyed the inits before. So I propose to change it to lazy init like: SWStructure>>initialize self initializeActions. self initializePermissions. SWStructure>>initializeActions self actions add: SWLogin; add: SWLogout; add: SWSearch; add: SWTemplateEdit; add: SWRecentChanges; add: SWPreviousStructure; add: SWParentStructure; add: SWNextStructure. SWStructure>>permissions ^permissions ifNil: [permissions := Set new] SWStructure>>actions ^actions ifNil: [actions := Set new] Also we should change every direct reference to 'actions' or 'permissions' to 'self actions' and 'self permissions' in this example. This lazy init would affect Structure, HtmlWriteStream and Template (AFAIK). regards Chris Burkert -- http://www.chrisburkert.de/
