[T5] radio group inside loop

Hi All,
I'm having trouble getting a radiogroup to work as I expect inside a loop.
This is what I have tried:

<t:loop source="myObjects" value="myValue" encoder="myEncoder">
    <t:radiogroup value="myValue.status">
        <t:radio value="statusA"/>
        <t:radio value="statusB"/>
    </t:radiogroup>
</t:loop>

The status variable I want to be selectable is an int and I have
corresponding public methods for statusA and statusB that return different
int values.

But this throws a NullPointerException (at
org.apache.tapestry5.corelib.components.RadioGroup.setupRender(RadioGroup.java:176)).

Can anyone shed any light on what I'm doing wrong?

Many thanks

Jack

I hang my head in shame. I hadn't yet put in any t:form tags so the
radiogroup had no formsupport object.
