There are no "redoStack, undoStack" fields in Diagram Controller class.

Using SyncFusion Explorer, navigating into "Diagrams samples" / "Samples" / "Quick start" / "Custom Command", then I clicked "RUN SAMPLE" button.

But there are errors during compiling that project.

Messages are,

"Error 1 'CustomCommand.CustomDiagramController' does not contain a definition for 'undoStack' D:\Program Files\Syncfusion\Essential Studio\4.2.0.37\windows\Diagram.Windows\Samples\Quick Start\CustomCommand\cs\CustomDiagram.cs 85 21 CustomCommand_2005
"

What can I do next?

----------------------

(I tried to view the source, "DiagramController.cs" file, As it would expect, there are no fields about redoStack, undoStack)
