What about if I create a custom widget which renders inside a <div>?

That is the server side of things. What about rendering those links so
they trigger the right javascript? In particluar, I'd like to render them
as if they are mapped to actions, so that when clicked, they will trigger
the server side Action that will do the work.
In order to achieve this, I need a way of creating a Link widget and then
ask that Link widget (actually its LCA) to return me the text of its
rendering so I can put it instead of the link in the html. The widget will
also render the listeners. How can I do that? As far as I could see, the
JSWriter always tries to write to the HTML response
Thanks,

Hi,
of course you can try to write your own custom widget. However, this is
the more complex task comparing to my suggestion above.
If you want to render abitrary HTML the best way to do this is using an
IFrame (as the Browser-Widget does). However, then you have the problem
that communication from within the IFrame to the rest of the app via
JavaScript is complicated.
What is your Use Case? Maybe there's an easier solution for this...
Regards,
Stefan.
