Running on Vaadin16

I recently upgraded to vaadin16. A page with a multiselect-combobox shows the following message in the top right corner:

Hi @jensgoe,

Which version of the MultiselectComboBox are you using? Also, have you tried to reproduce it on a new Vaadin 16 project or it happens after you updated?

[jensgoe]

I am using 2.4.0. But i just noticed you are already at 3.0.2. Great.
By the way. i have two projects. One is pure java there your MultiselectComboBox works. The other one is Polymer based and there is the error message shown. So i guess it is kind of misconfiguring.

Here is the version information: https://github.com/gatanaso/multiselect-combo-box-flow#version-information, so for Vaadin 16 you should be using 3.x.x of which 3.0.2 is the latest. For the polymer based project please see: https://github.com/gatanaso/multiselect-combo-box#getting-started
