Hi,
Isn't it better to disable the disable the button itself if it
shouldn't be clicked anymore ?

I guess it doesn't work because you do the work in onClick() and the
response is returned after finishing the processing of the data.
I see two solutions:
1) disable the link with JavaScript right after clicking it, then make
the Ajax call and finally enable it again when the ajax returns
to do that use IAjaxCallDecorator to insert the JS to disable the link
when clicked, and success/failure script to re-enable it when ready
2) Do the processing in a separate thread at the server side and then
check whether the job is finished with ajax timer behavior and when
ready re-enable the link
