How to: get selected tree node id

How to: get selected tree node id

The only way to get selected node's id is to use "tree_node_selected" Trigger.

void cb.data.tree_node_selected(char node_id, char parent_id) {
 
        :Global.selectedNodeId = node_id;
        :Global.selectedNodeParentId = parent_id;
 
        refresh_block('product_categories', 'id = ' || node_id);
}
