vaadin

I'm using vaadin 7 and in my application I use subwindows sometimes. In one case I have a modal window with several components in it. It opens another window when clicked on some of the components inside the modal window. I'd like this window to close automatically when the user clicks outside of it (e.g. on the modal window again). In the Vaadin Sampler this behaviour seems implemented when showing the source (click on the source button in the right upper corner). Also the behaviour should be the same if not opened from a modal window, but from the UI or any other subwindow. I tried several

My question is short (and hopefully simple to solve!): How can I completely disable browser-caching in my webservice realized with vaadin ? I want to completely disable caching since I'm getting problems when I try to do some PDF streaming and displaying them in my browers. I have read about a solution for my problem for example here: Using <meta> tags to turn off caching in all browsers? They talk about adding some headers to the web application that disable browser caching. But how do I add them to my Vaadin application? A short code snippet would be very welcome (and helpful!) Thanks once

The AbsoluteLayout in Vaadin 8 ( Framework ) enables pixel-position-oriented placement of widgets within a layout. While not my first layout of choice, the AbsoluteLayout is suited to porting code from other UI-building platforms that use pixel-position-oriented layout. Example code from the manual : // A 400x250 pixels size layout AbsoluteLayout layout = new AbsoluteLayout(); layout.setWidth("400px"); layout.setHeight("250px"); // A component with coordinates for its top-left corner TextField text = new TextField("Somewhere someplace"); layout.addComponent(text, "left: 50px; top: 50px;"); I

I'm a developer with a problem ;) Currently we're close to an end on our project (using Vaadin) however... we're getting some trouble with displaying simple data in one of our views. (over 500 KB of data to display, and over 15K DOM elements after Vaadin is done with generating it... + lots, and lots and LOTS seconds before it's done). My task is to find out how i can make this as small and as fast as possible, so my first guess was to use some other layouts than those avaliable in standar Vaadin. I used WeeLayout, DashLayout and CssLayout(default), compare is below: weeLayout - page size: 990
