Just to bring to ppls attention, there\’s a new removeAll method on the tree node. Looks like its only in version 3.2 and not 3.1 (worked that out the hard way). removeChild also doesn\’t work in 3.1 but fixed in 3.2.

Hi, I am trying to remove the nodes like in your example and than add them again. Firstly I have a memory leak after that, and also sometimes i have an awfull “this.target is null
error source line: [Break on this error] Ext.ToolTip=Ext.extend(Ext.Tip,{showDe…ithin(this.target.dom,true)){return;}” error );
