Hi Craig,
sorry, if this is totally OT, but I just posted a similar question in
the sun forum: Where would you actually place the code you mentioned
within a JSF component? I mean beginEncode() is called each time the
page is requested so what can I do, if I only want to add a component
once? I don't think that implementing NamingContainer and calling
findComponent() is a really nice solution ...
Thanks,
Tom
