Method that executes the Undo and Redo

Classic Servoy
1

Hi all,

I would like to make a method that executes the Undo and Redo that are under the Edit menu in Servoy form.
I looked under Forms controller but I couldnt find any that do Undo and redo.
Please advise,

Abrahim

Look under the APPLICATION node:

application.undo()
application.redo()

Bob,

I created a method that has only application.undo() ".
Any time I call it gives me error: Java.lang.ClassCastException

Do I need to add any parameters within ()?

Please let me know.

Thanks,

Abrahim

What version of Servoy?
What does your .log.txt file say (in the root of your Servoy folder)?
