I can't see why wicket could not be easily enhanced to support multiple overridden child sections. Just like the astract methods of a class - there is no limit on the number of them: a class can have any number abstract methods and they can be overridden by any derived class - not just immediate descendents and they don't have to all be overridden in the same class - just so long as an implementation is provided somewhere in the inheritance hierarchy for any concrete class. In wicket the <wicket:child> is just a placeholder for content that will be implemented/provided in a derived class. It just seems strange that the number of possible placeholders, n, was arbitrarily set to n = 1 in the architecture. Having only 1 alleviates the need to identify the placeholder in a derived class but that is the only reason I can see why the maximum number of placeholders should have been limited to just 1. I can see many uses for providing implementations of different child sections at different levels of the hierarchy. You could have navigation column, main column and footer being child sections. With a deep hierarchy you could provide 'extend' sections that provide the content for the child sections at various points in the hierarchy. You might provide footer markup via one common base class and then in classes that extend that class provide different navigation and main column markup but they all share a common footer. Another class might provide a different footer and have other classes extending it that provide different navigation and main column markup. For backwards compatibility with the current system you could say that if there is only one child section then no label is required but if you choose to add more than one child section then you must label them (just like providing an abstract method signature). ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
