Icefaces command link doesn't work on my local solairs

Question

I use Icefaces to develop a web app. The weird thing is I can't trigger the command link when I deploy it to my local instance and test it on FireFox of Solaris. But when I use my laptop (Windows Vista) to visit the site, it works just fine. I also tried to click the button from another workstation of solaris, but still doesn't work. Any help is appreciated.
