ERROR: Instance node ... must be detached from its current parent before it can be attached to another parent

Reason:

You attempted to attach an instance node to an edge node, but that instance node is already attached to another edge node.

Resolution:

Detach the instance node from its current edge node before you attempt to attach it to another edge node.

Tips:

• Is the instance node name correct?
• Find the edge node to which the instance node is attached by using the star$nodes view.
