Q: In iClient for Javascript, the select Feature gets the current feature to modify the style. Then add it to another vector layer, and drag the map. Why is there an error “Uncaught Not Found Error: Failed to $exeeute remove Child on Node: The node to be removed is not a child of this node”?

A: In this case, the feature is not loaded onto another vector layer. So when you use the remove All Features() method, above error shows. You can just use clone() the current feature.
