Have Only one node (chekbox) selected at a time

[c623700]

I try to force the list of nodes to only have one "isChecked" node by calling a function that would update the data from the onCheckToggleCb but to no avail.
here is the code:
<SuperTreeview
....
onCheckToggleCb={(arrayOfNodes, depth)=>{
this.handleCheck(arrayOfNodes);
....
/>

handleCheck(arrayOfNodes) {
    const isChecked = arrayOfNodes[0].isChecked;
    const nodeId = arrayOfNodes[0].id;
    var data = this.state.data;

    // if the node is being unchecked, leave data alone (it will update itself)
    if (isChecked) {
        // if the node is being checked, "wipe out" all the "checked" node in this.state.data (should be only one)
        applyCheckStateTo(data, nodeId);

        // Set the updated data in this.state.data
        this.setState({data: data});
    }

    function applyCheckStateTo(data, nodeId){
        data.forEach((node)=>{
            if (node.id != nodeId)
                node.isChecked = false;
            else
                node.isChecked = true;
            if(node.children){
                applyCheckStateTo(node.children, nodeId);
            }
        })
    }
}

Previous response suggested that is any properties need to be modified, it can be done on the onUpdateCb function, but how do I know (from onUpdateCb) which node to leave check and which node to uncheck as "arrayOfNodes is Not pass to onUpdateCb.

Appreciate any help
