Actually, on reflection, I can't really think of a good way to get
everything I want for free anyways. I think I will need to develop a
custom component, probably something that is composed of other
existing UI elements. The three primary use cases I'm looking at
currently are a dynamic, editable table with at least 2 text fields
where rows can be added/removed without the need to roundtrip to the
server, an editable, dynamic table with a drop down list and a text
field in a row where rows can be added/removed without roundtripping
and an element where a user can add multiple file upload elements
without having to roundtrip. i don't really see a way this can all
be done in JSF without using custom elements.
Of course, I'm open to suggestions.
Not really suggestions, I see it as you, there is no real free lunch
in this case, but hard work.
But there is a small project on sourceforge which already has an ajax
component in place, not something as sophisticated as what you want to
do, but you can check it out it might give you a headstart with your
things (and also a small push towards donating code yourself if you
want :-), your components sound interesting )
I have looked at those components. Very neat. I'm a little curious why
you didn't use the DWR library
(http://www.getahead.ltd.uk/dwr/index.html) for doing the AJAX stuff.
I'll definitely consider donating the code and it shouldn't be a
problem, just have to clear it with the higher ups.
the project is http://sourceforge.net/projects/jsf-comp the only ajax
component currently is an autocomplete field, which basically does
some element tinkering (blends in a filled div on demand which
simulates a drop down box), also there is an excellent OO javascript
library which is under MIT license, which delivers some effects and
good ajax classes.
The ajax component however does not use the Prototype OO lib yet, it
still uses a somewhat hackish messy code which was taken from the Sun
blueprints catalog and hacked in no time to IE compatibility.
Also there is the Sun blueprints catalog which has some ajax stuff in
there already, on java.net.
