Hello, I am looking for examples of "undo/redo using the Command pattern, I did not find any example that helps explain the use of this pattern for this case .
Suppose I have a text box, when the user changes the value of this area and tap "Enter" an RPC is launched to the server to save the change. I wanted to add a button "undo"so that when the user clicks over the text area takes the previous value and an RPC is lunched to update the value in the server and take into account the undo. I also wanted to add a button "redo" for the opposite behavior. Could you give me an idea about how to implement this behavior with the Command Pattern? Thank you in advance for your help I use GWT 2.3 on Eclipse 3.6. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
