This is very cool, I was not aware about such things. I like the idea so much, that I added this example and some others to the callback-demo action in the bundle 'SmallWiki Examples'. html anchor: 'Inspector' to: self url callback: #inspect. html anchor: 'Browser' to: self url callback: #browse. html anchor: 'Debugger' to: self url callback: #halt. One could also create a template-component for developer (only) to have those commands always at their fingertip. I also changed the semantics of the callback slightly: A callback is now removed from the cache, after being executed. I think this solves some problems with blocks getting executed twice, when refreshing a page or going back and forward with the browser. As we do not have continuations (yet), it makes no sense to keep them cached. Cheers Lukas -- Lukas Renggli http://renggli.freezope.org
