I have an entity 'Application' which has a ManyToMany association with Users.
I've been trying to get a pick-list up on the ApplicationForm so that this
relationship can be managed. I'm following the example of userRoles in the
default userForm, but whenever I send a non-empty list for availableUsers to
the form (from ApplicationFormController's referenceData() method), I get
the following exception:
javax.servlet.jsp.JspTagException: 500
/WEB-INF/pages/pickList.jsp?listCount=1&leftId=availableUsers&rightId=applicationUsers

Does this makes sense to anyone? Is it because I need a PropertyEditor?
