Our VaadinUI 1.2 is available!
It's a feature release with some bugfixes.

The biggest change was the update to vaadin 7.1.15 and we've already 7.3.3 in our development branch (welcome Valo theme).

What's new?

• Download extension

  Download dynamic content on-demand or whenever you want via WebSockets. More information and an example project for this extension.

• Configuration of preserveOnUIRefresh

  Simply use preserveOnRefresh as init-param (true | false) in your web.xml or as URL parameter to preserve the application on browser refresh.

• Use external CSS

  Use an external CSS file to configure your application style. There's no need to change genereated styles.css for simple tasks. Simply configure the init-param externalCss, e.g.

  <init-param>
    <param-name>externalCss</param-name>
    <param-value>../demoapp.css</param-value>
  </init-param>

  Place the demoapp.css in the root directory of your application (not application server ROOT).

  The css will be placed at the end of the stylesheet links in the generated index.html page.

• Mobile check

  We check if the UI is running on mobile browsers and set parameters for your application: Web.mobile (= VaadinUI.PROP_MOBILE) and Web.mobile.tablet(only for iPad at the moment) (= VaadinUI.PROP_TABLET). Simply check the parameter in your application.

• Cache for dynamic images

  If you use images from your classpath, vaadin generates internal URLs for you. This URLs are different per image and the browser cache doesn't work. This handling produces unnecessary requests. We solved the problem with an image cache on server side and custom Image resources. With this changes, the browser cache works as expected.

• IDs for menu items

  We have an experimental solution for setting IDs on menu items. It's experimental because it's possible that vaadin implements support for that. In that case we won't need our solution anymore. But till then, it works. More information...

• Responsive support

  It's now possible to register a resize event on the application launcher. Use this event to change your application on-demand. We have some impressions for you.

• Self-contained packages for Portlets

  We have built-in support for self-contained portlets. It's possible to toggle between global and self-contained mode. Simply set the init-param vaadin.shared (true | false) in your web.xml to use vaadin shared from your application server or the self-contained vaadin.

  General information about self-contained packages.

• invokeLater and WebSockets

  We've completely changed our invokeLater mechanism because it didn't work in previous versions.
