I just lost a few hours on a problem where an ajax operation on a Panel
nested in a Fragment was failing as my nested panel could not find its
associated markup. It seems this was because a Fragment will only
reliably find its markup if you explicitly provide it with the Component
that contains its markup in the Fragment constructor.
If you don't, Fragment.getAssociatedMarkupStream() will find its
markupProvider field is null, and so have to take a guess at where its
markup might be. If your fragment usage happens to be as a direct child
of the component that defines the fragment markup then it will all work
out, but if you have nested it in something like a ListView then it will
fail.
...So watch out kids, if you use fragments, use a constructor that tells
it where its markup is. Would you like to have to guess who your real
parents are? I think not.
