Hi,
I am getting the following JScript Error when dropping an node on another one.
Microsoft JScript runtime error: 'this._backupCollapsedNodes[...]' is null or not an object
Any Idea?
Thanx
[Update]
This only happens, when the node wich is dragged is empty. If the dragged node contains childnodes, the error does not occur.
I am using the newest release of the controls.

Hi,
one more addition. It looks like the error occurs when inserting the node clientside: destinationNode.get_nodes().add(sourceNode);

Hi, has this been resolved? I am getting the same error. I am using version 2008.3.1125.20 (can't find a version 2008.3.1125.35?).
It happens after I expand a node, then unexpand it, and then move it to somewhere.
It might be because I have this function:
function ClientNodeCollapsed(sender, eventArgs) {
var node = eventArgs.get_node();
tree.trackChanges();
node.set_expandMode(Telerik.Web.UI.TreeNodeExpandMode.ServerSideCallBack);
node.get_nodes().clear();
tree.commitChanges();
[...]
}
All my nodes are ServerSideCallBack because they have to constantly check for changes.
Would appreciate a way around the error
Thanks,
Fredrik

The operation I am performing: client side refresh node using AJAX to RadXmlHttpPanel
I just upgraded to version 2012.2.912 and I am now getting "'this._backupCollapsedNodes[...]' is null or not an object" error randomly when I try to refresh a node (remove all children, call back to server to get child nodes and then add them to the tree).
I was getting "Unable to get value of the property '_getHierarchicalIndex': object is null or undefined" when refreshing the node for which I have not yet seen a response from Telerik that it is fixed so I ended up with a workaround where if I catch that exception, I retry the operation and it always succeeds.
