问题 I have a GWTP MyPresenter that registers a handler at onBind(), and it works perfectly. The problem is when I leave the presenter using the BACK arrow on the browser. The onUnbind() is never called (I tried with an breakpoint overriding the method, but is never executed). So that this handler is never unregistered. What is wrong?

问题 I am trying to select a div node based on its CSS ID, and change the div's text, all with jQuery (2.2.0). My problem is that jQuery selection never seems to happen normally? That jQuery selection code (below, where I'm using the '$' shorthand for 'jquery' fucntion) is within a standard 'document ready' callback function so that the div with CSS ID is "supposedly" ensured to be in the DOM by the time the callback is called. That js code, and its standard JSNI $wnd syntax, resemble the Answers

What I want is to first check if the user is logged in and then create a CurrentSession object or something like this. But how can I pass/inject this object around? At

问题 I started to use GWTP for my project and I'm currently re-writing all my code to let it work with this library. However, I struggle to understand how I use GWTP if I want e.g. a ListView with ListItemView items. @Inject public ToolsPresenter(PlaceManager placeManager, EventBus eventBus, MyView view, MyProxy proxy) { super(eventBus, view, proxy, AdminToolPresenter.SLOT_AdminToolMainContent); this.placeManager = placeManager; ToolListView toolListView = new ToolListView(...)
