Component sizes are not sent back to the server by the Vaadin standard components. Since all of your code is

问题 I'm trying to create a simple theme (using Chameleon and some custom css and images, etc), which I've done. The problem is I want to wrap it up in a maven project and reference from other Vaadin projects as a dependency, so I can theme all my Vaadin apps the same way - or even better have it as a dependency of the parent project so that the whole app gets styled the same way and I can re-skin it for different customers.

问题 By using "Spring Stater Project" in Eclipse/STS, I was able to have a Vaadin project up and running quickly. I want to add charting via Vaadin-Addon to the project.

问题 I've read the other posts regarding this topic already. I just want to clarify, is there really no way in vaadin to: Create a custom layout html file, like custom.html; Import a java script file to it, then...; Call the js functions from within the html file, like one would normally? Currently I have home.html in my Vaadin\themes(project)\layouts and a javascript library in Vaadin\js\custom.js. In my Panel class i have annotation @JavaScript({"vaadin://js/custom.js"}) , and in my html i tried
