if your read/write JSON from your drawd2d diagram, it is important that all elements has the attribute NAME. This attribute is use late to create JS object instances. https://github.com/freegroup/draw2d/blob/master/examples/connection_with_contextmenu/MyConnection.js#L12

If this attribute exists, the constructor of your Connection class is correct called and the coding for the cotext menue is executed.
