Hi,
I have made a recursive delete option for the asynctreenodes. Why i made this function is simple. I want when a node is collapsed all the nodes are deleted and when expanded again i want to load the content again. So that changes in the tree are reloaded again. I tried to use the reload method but this resulted in a infinite loop :(, I don't know if this is the right way but give me your feedback and maybe it is in any use for you.
var Tree = Ext.tree;
var tree = new Tree.TreePanel('treePanel', {
animate:true,
loader: new Tree.TreeLoader({dataUrl:'http://www.somewhere.where/your/feed/is'}),

The right way is to use reload().
And if it causes an infinite loop, then it's either an Ext bug, or your bug.
You could try stepping through reload and seeing what it's doing. It looks quite simple really:
reload : function(callback){
this.collapse(false, false);
while(this.firstChild){
this.removeChild(this.firstChild);
}
this.childrenRendered = false;
this.loaded = false;
if(this.isHiddenRoot()){
this.expanded = false;
}
this.expand(false, false, callback);
}
It removes all children (recursion not necessary - the child nodes of the child nodes are just abandoned), and clears the childrenRendered and loaded flags. What could go wrong?
Does the loop occur when it attempts to re-expand (and therefore reload) the node?
When i say reload on the onexpand event it keeps on reloading. Because the reload function keeps on calling the expand event. Thats why it goes into a infinitive loop. And thats why i came with this solution.
You have a listener on the "expand" event of the tree which calls reload?
