A4J CheckBoxes

I have tried to don't include the list in a4j reload, but the problems exposed below still persist.
I really think it is better not to use a4j here...

Here is the original mails :

Ajax 4 JSF on checkboxes is at least useful for one thing: update the "disabled"
attribute of bottom buttons (copy / paste / delete) according to the rights and
the state of the document you have selected.

As for reupdating the state of the list, I think this is a design mistake since
it is not scalable:

load 100 docs or more in your repository, go to the search form and do a "SELECT

• from Document" to get a flat clipboardable list of all the documents in your
  repository. Every time you click on a checkbox the request is redone just to
  updated the selected state of the checkboxes. If the request time is longuer
  than the delay between two checkbox clics, you'll get an error.
