how to put data in session variable and get the data in different page in vaadin?

由 前提是你 提交于 2019-11-29 04:32:54
I think I should use the application scope session to deal with that. But I do not have any experience about that. I tried different ways I got from the internet like: HttpServletRequest request; HttpSession sess = request.getSession(); sess.setAttribute("name", name); later in other page HttpServletRequest request; String=(String)request.getAttribute(name); //or HttpSession sess = request.getSession(); // sess.getAttribute(name); all do not work. I think there may something special for vaadin to deal with that. Please help me. Basil Bourque Two Levels Of Scope See this posting by Roland

How to integrate GWT or Vaadin with Play Framework 2.0

由 天大地大妈咪最大 提交于 2019-11-28 21:29:15
Is is possible to implement the client side of a Play Framework 2.x web application using GWT or Vaadin? Play 1.x has a special module that provides GWT integration, but I can not find examples of the use of these technologies together in Play 2.x version. Can these technologies be integrated? Is there a module, or must some other approach be used? GWT and Play2 can work together seamlessly, just as GWT can be used with python and go backends. Using GWT with Play2 has two parts, serving static files and client-server communication . For the GWT produced static files (js, css, img..) you can

问题 I want to change data inside a Vaadin UI. The change is invoked by a a rest call. There, i somehow need a reference to the UI class to call its method´, e.g. changeValue(string value).

Vaadin 8.5.1- Refresh grid after row update

由 感情迁移 提交于 2019-11-28 10:36:46
问题 I am using Vaadin 8.5.1 Grid to display 1000's of rows. Once a row is updated with change in it property, I use grid.getDataProvider().refreshItem(selectedRow) or grid.getDataProvider().refreshAll() which fails to update the row. I need to do explicit grid.setItems() to see the updated property of the row. I am using below snippet to create a Grid msgGrid = new ABSMsgGrid(); List<ConsoleEntry> messageEntryList = new ArrayList<>(); if (inputConsole != null) { messageEntryList.addAll

Where to store `UI`-object scoped state in a Vaadin 14 app?

由 江枫思渺然 提交于 2019-11-28 06:49:04
问题 Context (web app) To store state available to our entire Vaadin app, we can get and set "Attribute" on the VaadinContext object that represents our entire Vaadin-based web app at runtime. These attributes act as a key-value collection, where the key is of type String and the value is of type Object . We access the context by calling UI.getCurrent().getSession().getService().getContext() . Session (per user) To store state available to any one user’s session, we can similarly get and set
