I've run into and known all that bugs of IE of onchange and the issue of using onclick. So I used a combox to replace the radio button. OnChange works fine with patial refresh in both IE 8 and Firefox until...

One day an user reported the he couldn't change the combox value. I tried and found the page worked at first, but after you left it to "rest"

for a while, you couldn't change the combox value -- it just jumped back.

The partial refresh switch the display of two check box groups.

rendered="#{javascript:document1.getItemValueString('Type')==='Route'; 

 

This weird thing occurs both in IE 8 and Firefox.

Any suggestion would be appreciated.
