I am trying to modify the demo example to my needs and found that
1. Although none of the attributes of this tag are required, I found that I cannot remove "for" attribute.
2. javascript function attached to the filter "oncomplete" is never called.
3. I see that multiple instances of the session backing bean are created for the sliderlistener attribute. I have a a4j:jsFunction on the same page, and the result is that this javascript is accessing a different backing bean then the one which has the value of the slider set.
