Hi all, it seems like we cannot cast the class of object to its subclass if that subclass has had new instance variables added to it:
http://forum.world.st/changing-the-class-of-an-existing-object-to-a-subclass-td4239041.html But I (think) I need it - I'm transforming a DOM tree from XMLHTMLParser's XMLElement s to a subclass of Iliad's ILHTMLBuilderElement s, and for single occurences I would like to use the more specific subclasses, like ILCheckboxElement. I can make the cast manually, I know when it is safe to do. What else could I do, apart from removing the element from its tree, creating a new (subclass) instance and then putting this element in place of the old one? Some #perform or `super` magic..? hm.. thanks for any pointers! -- Siemen
