Hi When using Builder::XmlMakup, I found a bug when trying to use .tag!(''p''). After some tests I found out that the problem lies within the __send__ call in .tag! . __send__ obviously prefers the functions mixed in via Kernel to the method_missing. My own quick fix was to call method_missing directly (changed the line from self.__send__(...) to self.method_missing(...) in builder/xmlbase.rb). I''m not sure this is the correct way to do this, anyone any suggestions? It seems to work fine though... Where can I post bugs like this by the way? Kind regards, Flurin Egger
