Well, one thing you can do is have the EntryPoint, and just tell plugin
developers that they have to attach to some particular div element in a
particular way, as opposed to the traditional root (i.e.
RootPanel.get(plugin-name-div)).
Then the user can request certain plugins to be added in which

browsers - I'm not sure which support it (although I suspect all of the
major ones).
Good luck.

Sounds like a bug - you should file a bug (under the issues tab of the

If you figure out a workaround in code, you can hide it behind a deferred

It's not really a matter of this being GWTs way. I believe this is the only

that the UI doesn't lock up. And by UI lockup, I don't mean the page is
