I integrated the Stepper Vaadin component into my project as described on https://doc.cuba-platform.com/manual-6.8/vaadin_addon_sample_gui.html
It works fine when used by manual insertion into an xml form descriptor or creation by controller code. But there is no Stepper component in UI designer palette and there are no specific stepper properties on the Properties tab.
I found 2 lines in the studio log:
2018-05-24 13:18:38,822 INFO [com.haulmont.studio.ui.sd.layout.ComponentModelMapper] Model class for stepper not found
2018-05-24 13:24:20,406 INFO [com.vaadin.server.VaadinServlet] Requested resource [/VAADIN/ace/worker-xml.js] not found from filesystem or through class loader. Add widgetset and/or theme JAR to your classpath or add files to WebContent/VAADIN folder.
Maybe I missed something when integrating the stepper?
