Link re-connection issue during undo / redo

I created an expandable node.
However, there is a problem that link is not reconnected during Undo / Redo operation.

Please hint to solve the problem.

We’ll look into this.

Thanks for reporting, we have fixed the related bug and this will be out with the next release.

I hope the bug has been fixed as soon as possible. Thank you for confirming.

We just released GoJS 1.7.14, which fixes this issue.
