Correcting mistakes

If you make a change in the Visual Composition Editor and then decide that you should have left things as they were, select Undo from the Edit menu to restore your work to its previous state. You can undo as many operations as you want, all the way back to when you opened the Visual Composition Editor for the current bean.

If you undo an operation and then decide that you did the right thing in the first place, select Redo from the Edit menu. Redo will restore the view to the state it was in before the last Undo. As soon as you close the Visual Composition Editor for your bean, you lose any ability to undo or redo changes.
