Bean DataSource is an alternative for Vaadin Container that is focused on Beans. It provides typed content for typed components. This Add-on provides a few interfaces that make communicating data for your component easy and automatic. You provide the information on what you want from the bean to the client-side, and this add-on takes care of communication and possibly lazy loading. It is still missing some features like applying filters and sorting, but I wanted to release it so it can be tested. Feedback is appreciated. See http://github.com/tsuoanttila/bean-grid for example usage.
