How to delete a node off the tree?

This shouldn't be that hard, should it? I need to search through the store to find nodes that meet a certain criteria, and simply delete them (be they leaves or branches)?

Here's what I've got:

Code:

---

var store = tree.getStore();store.doOnLoad(function(store) {
    var root = Ext.valueFrom(null, tree.getRootNode());
    root.cascadeBy(function(node) {
        if (node.get("archived") == true) {
            store.getById(node.internalId).remove();
        }
    });
});

---

It's throwing a "childNodes[i] is undefined" error: childNodes[i].cascadeBy(fn, scope, args); [ext-all-dev.js (line 56625)]

Since it's throwing that inside a recursion loop, it would seem to indicate that it doesn't know to not follow that branch when its ancestor has been deleted. But that's only a guess at this point.

Been beating my head against the wall for far too long on this one. Any help would be greatly appreciated.

You need to use the removeChild method on the parent node
