[ANN] Callbacks, Session

Hi Smalltalkers, I have enhanced and changed a lot of things in SmallWiki over this weekend. The most exciting thing is the support of callback-blocks, making the development of web-user-interfaces easier. You don't have to deal with Request and Response anymore. If you like, you might want to have a look a the actions, they have all been rewritten to use the new protocol. There is also a demo-action in the 'SmallWiki Examples' bundle. Load it, have a look at the source and point your browser to: http://localhost:8080/?action=CallbackDemo In rare cases there might be problems, if you have subclassed any action-classes or if you have created html-forms using the old framework. If you didn't got too low-level it should still work, but you might get a lot of warnings in the transcript. Have a look at the new messages in HtmlWriteStream and use these ones, as the others will be removed for the final version of SmallWiki. BTW: The callback-mechanisme is not limited to actions, it might also be used within the templates, visitors, documents, etc. The changes related to the session-management took place at a very low level, so - I think - nobodies code will be touched. There were a lot of problems with the basic-authentication so far, so i decided to switch to cookie-based implementation. Another advantage is that one is now able to logout. I think this will work more reliable, but we will see. Cheers Lukas -- Lukas Renggli http://renggli.freezope.org
