Hi.
My custom object consists of several GoShapes.
- Move the object and record the transaction.
- Move the object without transaction recording.
- After Undoing, GoStroke does not appear in the expected location.
What is the problem?
※ In my actual project, some custom objects are automatically aligned to the right as the view size changes
The automatic alignment behavior should not be recorded in transactions.
Here is the test source code.

public Form1()

this.view = new GoView() { Dock = DockStyle.Fill };
this.Controls.Add(this.view);
this.view.Document.UndoManager = new GoUndoManager();
this.view.Document.UndoManager.ChecksTransactionLevel = true;
var button = new GoButton()

Text = "Test",
Location = new PointF(10, 150),

this.view.Document.Add(button);
var text = new GoText()

button.Action += (s, e) =>

this.Add(r);
var s1 = new GoStroke() { Selectable = true };
s1.AddPoint(70, 60);
s1.AddPoint(90, 90);
this.Add(s1);
var s2 = new GoStroke() { Selectable = true };
s2.AddPoint(90, 60);
s2.AddPoint(70, 90);
this.Add(s2);
}
}
}
