  1. Range slider

    Filtering data that are presented in a list or table is possible with multiple UI components. Most of these components are however restricted to a single value. Especially sliders are very easy to use for users that are likely to specify a range of values. Thus, I suggest you extending the slider component to allow the specification of a range. If a table, for example, lists products described by price and some other attributes, a range slider might be useful to narrow down the entries in the table by simultaneously specifying a minimal and a maximal price.

    • Add a tooltip *with some visual indicator*.

      The standard way of adding a contextual help to Vaadin components, through using the setDescription(String) method is nice, but what my team has found lacking on multiple occasions is the ability to indicate to the user that a given label, field, etc, will display such info when hovered over.

      Would it be possible to add functionality displaying a little question mark icon, or similar, next to a tooltipped field? The question mark icon should display the tooltip when hovered over or clicked.

      • When validating required field, error indicator should replace required indicator

        When validating required field, error indicator should replace required indicator. When field is valid, indicator should go back to required.

        • Provide onVisible

          There is no means of performing code execution immediately after a screen is painted for NavitationView. There is a method called onBecomingVisible which is right before JsonPaintTarget.startPaintable/endPaintable is called. This is before the painting. Maybe something called "onVisible" for NavigationView. This onBecomingVisible/onVisible should also be available for Desktop too.

          • Add a validator that can validate multiple dependent fileds at once

            Say you have a form that has a start and end date fields.

            If the start date is later than the end date, both fields should be marked invalid.

            As soon as either field is edited so that the end date is later than the start date, both fields should be marked as valid.

            • Create a generic "ComponentRenderer" for grid

              I think it would be nice to have a generic "ComponentRenderer" for the grid.
              The idea is so pass any component to the renderer and the grid just displays it. The component's functionality should be defined by the component itselt (e.g. Button, Link, Label).

              In the old table the same feature exists in a similar way, using a ColumnGenerator.

                  • enable smooth integration with OSGi

                    I and others want to be able to write web application bundles for OSGi with Vaadin, but it's not as quick and straightforward as one would think it would be at first glance.

                    One example of the efforts required to get Vaadin working with an OSGi bundle are documented here: http://wiki.rpgnextgen.com/doku.php?id=vaadin_7.4_osgi_web_application

                    • To free the mobile toolkit (TouchKit)!

                      ZK (IMHO, Vaadin's closest competitor) provides mobile support, out of the box, with no charges for its community version. Nowadays responsive interfaces are a most in every web application, it would be very nice if Vaadin includes at least a minimal support for the basic UI controls, and even nicer if this support could be incorporated in a transparent way (no extra code)

                                this is useful for providing instant state feedback related to a previous item selection event.

                                • develop a component with scrolling text like news ticker

                                  A scrolling text component would be a useful addition to vaadin. Scrolling text can have varying speed, font, width, transparent or solid, foreground color, background color, vertical or horizontal direction and location. Option to run once or in a loop or after fixed intervals.

                                  • Dynamic locale change

                                    This was a voted feature for V7, but there are no signs of it anywhere. Vaadin people think underestimates this because you only need to restart the app or build yourself the logic to update content wher locale changes. IMO portal environments are widely used, and there you cannot happily restart portlets because language has changed. And it's not so easy to do it yourself. In fact Pedro Rodriguez and I made a library to do that, but it's very chanllenging and all components have to be extended to include new methods. I insist again and whenever needed that I18N…

                                      • Allow ComboBox items to have different CSS styles

                                        this is useful for providing instant state feedback related to a previous item selection event. For example, the Labels in a ComboBox could change styles depending on which item(s) were previously selected or depending on what capabilities are currently enabled based on a prior item selection.

                                        • Better theme integration, style design with Liferay

                                          I'ts very difficult for me to make Vaadin portlets look like the portal. There are lots of divs, wrappers, ... It's not easy for a component or a custom component to set it's style. Web designers get crazy to know how to set it. Even worse, it's not easy to change the style at runtime.
