The problem was basically because there is no good place to put this property and the following problems: - you could have multiple descriptions within the same form where auto-focus was set to true, especially when composing descriptions at runtime from several different sources. - #autofocus: did not work with some more complex form-elements like one-to-one, one-to-many, multiple-selection, ... - when changing from WAHtmlRenderer to WACanvasRenderer there was no replacement for the method #autofocus:, however this could be easily added again. - I felt that is unnecessary to have #autofocus: in the description itself, if you really need to automatically focus an element you probably do a sophisticated manual rendering anyway. - proper separation of view and meta-model, something Stéphane Ducasse and I just recently discussed: a problem in the current version of Magritte is that I mix meta-stuff and Seaside/Morphic configuration, such as #componentClass:, #attributes, #morphicClass, #autofocus: ... this should be the responsibility of a different object, not the description itself. It leads to some hard to tackle problems with extension-methods, if you want to use descriptions with/ without different view-implementations, however it is not easy to solve. Maybe something for Magritte 1.1 ;-) Lukas -- Lukas Renggli http://www.lukas-renggli.ch
