dataFilterSlider without slider listener
----------------------------------------

                 Key: RF-3719
                 URL: http://jira.jboss.com/jira/browse/RF-3719
             Project: RichFaces
          Issue Type: Feature Request
    Affects Versions: 3.2.1
         Environment: JSF RI 1.2_09-BETA1, IE 7 and FF 3.0RC3
            Reporter: Juergen Zimmermann


When omitting the attribute sliderListener and also a listener method I can drag the slider for the first time without any problem. When dragging the slidder for the second time I get this stacktrace (for both IE 7 and FF 3.0RC3):
