Set the expected value of the id part in your form model (the model
where the dropdown will store the submitted value).
when the dropdown renders it will use the existing value to preset the
choice.
In your code below, it looks like the model is created new every time.
for this to work, the model has to have the preselected choice set on
it, or it need to survive renders.
Your ChoiceRenderer simply tells the component which part is id and
which is display.

I have set the model. But I still don't see it preselected when the
dropDownChoice object is displayed:
form.add(new DropDownChoice<IParameterInOutType>(
"parameterInOutType",
new
CompoundPropertyModel
<IParameterInOutType>(parameterMetaData.getParameterInOutType()),
listParameterInOutType,
new
ChoiceRenderer<IParameterInOutType>("name")));
Am I missing some thing? DO I need to do something in the html?
Thanks.

hi, when using a DropDownChoice is there a way to have the value
preselected if there is only one available and the field is
required?
i have looked through the code but cannot see any settings that
might
control this, and am stumped trying to work out how to extend the
control in this way.
