Removing a TreeNode success but with error

[mitchellsimoens]

I'm trying to remove a node and it does remove it but I get this error:

TypeError: Result of expression 'b.ui' [null] is not an object.

I append nodes using this:

node.appendChild({
	nodeType: "node",
	text: name,
	location: location
});

Now I can do a try catch to get rid of the error popping up but that kind of defeats the purpose.

I only find "b.ui" in ext-all.js. Please use ext-all-debug.js since I don't feel like searching the right method in ext-all.js

Ok so now I get these errors:

TypeError: Result of expression 'node.ui' [null] is not an object.

Line 49154 is this:

    removeChild : function(node, destroy){
        this.ownerTree.getSelectionModel().unselect(node);
        Ext.tree.TreeNode.superclass.removeChild.apply(this, arguments);
        // if it's been rendered remove dom node
        if(node.ui.rendered){
            node.ui.remove();
        }
        if(this.childNodes.length < 1){
            this.collapse(false, false);
        }else{
            this.ui.updateExpandIcon();
        }
        if(!this.firstChild && !this.isHiddenRoot()) {
            this.childrenRendered = false;
        }
        return node;
    },

Line 48663 is this:

    remove : function(destroy){
        this.parentNode.removeChild(this, destroy);
        return this;
    },

The rest are cleaning up the events. When I tried doing node.ui.rendered it returned true. When I tried doing node.ui.remove() it removed the dom with no errors so I'm not sure why it's doing this.

I did a node.appendChild like you've mentioned in the first post. I didn't get any errors.
Do you have overrides/extends on TreeNodes? I think it would be helpful, if you provide some more code that can reproduce your issue (look around main.js line 57 ).
