addControl: Item has already been added to some node

[fogine]

I believe there is a bug in code here, causing exception when calling node.addControl https://github.com/retejs/rete/blob/76605fda249796667a05d9a687b3c852f70b54a6/src/node.ts#L28-L29

as when not using typescript, Control instance has parent property qual to undefined.

It's not a bug. Initially Control has parent = null. It seems that this control has already been added to some node, so you cannot add it again

There is no error. I got the same exception and my mistake was extending the class using

class CustomControl extends Rete.Component

instead of

class CustomControl extends Rete.Control

That's probably why you don't have the parent property defined.
