问题 I'm working with Vaadin 7, Eclipse(Juno) and Java EE 7. I want to use the Eclipse Vaadin plugin to create and compile Vaadin projects. The problem is that the Vaadin plugin insists on checking the vaadin website for updates before doing just about anything (and crashes my eclipse when it can't do it) - I am behind a very restrictive network and cannot use it in this way. I found this: https://vaadin.com/directory#addon/vaadin-plug-in-for-eclipse Which is a downloadable offline repo for Vaadin

问题 I want to prevent clickjacking attack in Vaadin 7 and 8 apps. As Vaadin applications are by default designed to be embeddable, some configuration or code is needed to add safety.

问题 I'm using Vaadin . I want to use Native Select to switch between locales. @Override public void valueChange(ValueChangeEvent event) { UI.getCurrent().setLocale(loc); } I wanted to use event.getProperty() but "loc" have to be Locale type.

问题 (Sorry if this is a bit of a newb question) I have two JPAContainers, one for an Employee class/table and one for Language class/table. An employee can have a selected language. I am trying to create an Employee editing form with a combobox for the language selection and FieldGroup to handle the binding and creation.

问题 Problem: I currently have a grid that displays content of type SomeModel . When I click an entry of that Grid I would like to navigate to a view that takes an object as its input to display the entries content. Implementation: To achive this behaviour I created a DetailLayout like this: public DetailLayout extends FlexLayout implements HasUrlParameter<SomeModel>{ /* skipped some details */ @Override public void setParameter(BeforeEvent event, Host parameter) { /* This is where I expected to
