I'm using CSOM to modify the checked nodes in a UltraWebTree, after the user checks one of them.

The example above helped to get me started - and I can verify that I am indeed calling

    node.setChecked = false;

for several nodes in my tree.

What I expected to happen is the checkboxes would be cleared in the browser window - but this is not the case... Do I need to set any UltraWebTree properties in order to enable client-side changes to the checkboxes?

Here is my javascript - MEWebTree_NodeChecked is called whenever any node gets checked, I un-check all nodes that are at a different level.

    function MEWebTree_ClearOtherLevels(node, newLevel) {

        var level = node.getLevel();
        if (level != newLevel) {
            alert("clearing node " + node.Id);
            node.setChecked = false;
        }

        if (node.hasChildren) {
            var nodes = node.getChildNodes();

            if (nodes != null) {
                var i = 0;
                for (i = 0; i < nodes.length; i++) {
                    MEWebTree_ClearOtherLevels(nodes[i], newLevel);
                }
            }
        }
    }
   
    function MEWebTree_NodeChecked(treeId, nodeId, bChecked) {

        if (bChecked == true) {
            //take action on each check
            var node = igtree_getNodeById(nodeId);

            if (node != null) {
                var nodeLevel = node.getLevel();

                alert(nodeId + " Level- " + nodeLevel + " Node Checked");

                // clear any checks at other levels
                var tree = igtree_getTreeById(treeId);
                if (tree != null) {
                    var treeNodes = tree.getNodes();
                   
                    if (treeNodes != null) {
                        var i = 0;
                        for (i = 0; i < treeNodes.length; i++) {
                            MEWebTree_ClearOtherLevels(treeNodes[i], nodeLevel);
                        }
                    }                   
                }
            }
        }
    }
