It would be great if the content menu can be customized depending on the items selected in a table. I mean, if two items are selected and context menu is open, it show show another options than whe only one of the is selected.
This is something that will hopefully be supported in the future. There exists custom patches for Vaadin 6 that enable using ContextMenu 3.1 in Vaadin Table. Looking forward for this kind of functionality in the core 7 some day.
