    check out the following demo project: https://github.com/matzew/modern-ee-app20 it works fine with codi 1.0.1, BUT I get an NPE when I use 1.0.2 (on the create dialog): http://localhost:9090/faces/new_person.xhtml --> click the <h:commandButton /> button in the page and (with 1.0.2 only...) you hit this stack trace: {code}
