How to resize one node with dynamic port?

Based on this sample:  https://gojs.net/latest/samples/dynamicPorts.html, I just  add one line "resizable: true,"  in myDiagram.nodeTemplate   part. after that,  as soon as I resize one node size by mouse, the ports'   positions   around this nodes  change  incorrectly  and  become messy.
 How could I fix this issue?    I really need your help!    thanks!

If you read about the ResizingTool, GoJS Tools -- Northwoods Software, you will see that you do not want to resize the whole node, but just the body. So give that Panel a GraphObject.name and assign Part.resizeObjectName.

Thanks, walter! the problem is fixed!
