Contributed ControlCheckbox, ControlledCheckboxes with given CheckboxGroup

[Shing Hing Man]

I have been trying out the contributed CheckboxGroup,
ControlCheckbox and 
ControlledCheckbox.
Everyhing is fine when  the ControlCheckbox, 
ControlledCheckboxes are enclosed
by a CheckboxGroup.
However, I have problem when my CheckboxGroup does not
enclose the
ControlledCheckbox  and ControlledCheckboxes. (In this
case, 
the parameter group in component ControlCheckbox, 
ControlledCheckedbox are explicted set to the
CheckboxGroup.)

In the generated html source, the ControlCheckbox is :
<input onclick="null(this.checked)"
type="checkbox"></input>

The above 'null' should be  setCheckboxGroup(value).


My code is pasted at the end.  (This example is
available online
at 
http://lombok.demon.co.uk/tapestry4Demo/app?page=TestCheckboxes2&service=page
)

What is the correct usage when the CheckboxGroup does
not enclose
the   ControlCheckbox,  ControlledCheckboxes ?

Thanks in advance for any assistance!
