Hi, I am using richfaces tree and encounter the below javascript error when a tree node is clicked in Internet Explorer. This error does not occur in Firefox. while(D&&Element.isChildOf(D,this.element)){C+=D.offsetTop; D=D.offsetParent }D=F; I tried using Richfaces version 3.3.1 (latest) and 3.2.1 but encounter the error in both versions. Has anyone faced this error? Any suggestions/comments appreciated. Thanks. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4247949#...
