ComboBox Multiselect

Hi to all.

I’m trying to use the Combobox Multiselection addon (1.1.14), with vaadin 7.5.10:!addon/comboboxmultiselect-add-on

But when I open my application I see this warning:

Widgetset ‘’ does not contain implementation for org.vaadin.addons.comboboxmultiselect.ComboBoxMultiselect. Check its component connector’s @Connect mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions.

I should only need the maven dependency, or I’m I missing something?


Hi again.

I think I got it working, in my gwt.xml I added the folowing line:

Clean all cache, recompiled the widgets and it worked… but this info is not in the addon page.



For future reference, I think the vaadin:update-widgetset maven goal should also do that same for you automatically


Hi all,

Is there a way to add scroll bar to the java vaadin combo box multi select option. I could only find a basic way to lazy load 10 components at a time. But I want to show all with a scroll bar.
Thanks in advance.
