Folks,

I am having difficulty with this widget.

It renders populated with items on the left side.

Upon clicking any items on left side... the border around the left side turns 
red (implying some security issue or items disabled or readonly)... I am 
guessing.

If I select any items on left side the ADD button up top never enables and is 
always greyed out.

The items I am rendering within this palette are enumerations... as follows:

public class Person
{
    public static enum Role
    {
        anonymous(1), administrator(2);
    }

    private Set<Role> roles = new HashSet<Role>();

    @CollectionOfElements(targetElement = Role.class)
    public Set<Role> getRoles()
    {
        return roles;
    }

    public void setRoles(Set<Role> roles)
    {
        this.roles = roles;
    }
...
}

Is there anything in the above class that would cause the palette to behave 
this way ?

I am using tapestry-security... but not sure if security would cause this 
widget to act this way.

Thanks for any tips

Ken
