Extension of Advance Steel

Hello guys,

We are customizing the Advance Steel Dynamo’s extension and we have had some issues when an AS object changes and then node of dynamo loses the connection with element’s handle.
It was resolved by saving the old and new handles inside a Hastable object in a LifecycleManager class.
But I need to fix it when the user saves dynamo’s project(.DYN). I’m thinking about change the value of tracedata or something similar…

Have anybody already done this? I found this function GetNodesFromElementIds in revit extension when I was looking for some cue… Maybe it will be the way of resolve this.
