### MVVM form can't take Checkbox

I've posted this as a bug, but I want to check to see that I'm not doing something dumb.

Following the MVVM listbox CRUD example, Ive found that if you include a checkbox in the form the app throw an error with:

     Error writing 'checked' on type org.zkoss.zul.Checkbox crash


I'm using R6.0.2
