[argouml-dev] help with issue 2463

[Andrea Nironi]

I need help with issue 2463 (http://argouml.tigris.org/issues/show_bug.cgi?id=2463): "Wrong downlighting of "Back" and "Next" buttons". What I don't understand is how the back action manages to go back to the ToDo description. When the back button is pressed it executes this code: ... public void back() { step--; if (step < 0) step = 0; undoAction(step); if (item != null) item.changed(); } ... The undoAction() always calls a blank method, AFAICS. On the next line, item.changed() fires a ToDoItemChanged event to every listener: the only one is ToDoPane. Anyway, the back action never calls the [WizStep.]enableButtons() method: that's the only method that enables/disables the backButton. I'd guess it's all a hiding panels game... but I don't understand how it's done, and where the steps calculation fails. It's driving me crazy...
