Vaadin 7 Grid does not yet have editor event. This is a small short coming if you want to create button to add a row to your grid with the following logic 1. Click button to add a row 2. Activate editor on the new row 3. Delete row if user selected to click cancel instead of save Hence I wrote this experimental add-on, which encapsulates needed logic in form of extended Vaadin Button. Notes * Works currently only with BeanItemContainer * Uses threads, hence Push needs to be enabled * Beans used with AddRowButton must have default constructor without parameters in order to intanstiate * Doesn't work with Vaadin 7.6.1 - 7.6.2 due layout bug in Editor * Doesn't work with Vaadin 7.5.4 and older due bug Grid row book keeping Status of this utility is experimental. I hope this is also useful demo case how to work with Vaadin using threads. ### Usage: Setup the Grid first. Usage - Create new AddRowButton using its constructor. AddRowButton button = new AddRowButton(String caption, Grid grid,Class MyBean.class); caption: the caption of the button MyBean: the beantype of your bean grid: the grid you use this utility with
