I wanted to install the experimental Eclipse plugin for Vaadin 6.3 + GWT 2.0 (at http://vaadin.com/eclipse/experimental), but the only plugin that shows up is 6.2. Is the beta 6.3 no longer available?
Okay folks… I figured it out. After installing the plugin, when you create a new Vaadin project, there’s an option to select beta releases (check box option at the bottom of the panel, with drop down list on the first screen). After selecting Vaadin 6.3 the beta release was thereafter downloaded and installed.
