after adding the combo box to my project i am getting the following error
java: cannot access com.vaadin.flow.component.HasHelper
class file for com.vaadin.flow.component.HasHelper not found

It may be due to Vaadin version you use. HasHelper is a new interface for the implementation of the helper texts. This came in Vaadin 14.4 and Vaadin 18 respectively. So if you use Vaadin 17 or Vaadin 14.3, the error is expected.

Yes, I’ve added the limitation in the description of the project. It requires Vaadin 14.4+.
The component is not working in Vaadin 18, due to some internal changes in the combobox.
