That's because Component#setDefaultModelObject is called internally. It
uses an IModelComparator to check whether the model object needs to be
changed. The default implementation uses an Object#equals() check. So if
the new value is equal to the old value it ignores the call.
If you want another behavior (e.g. reference equality or to change it
every time) then override Component#getModelComparator in your component
to provide an appropriate IModelComparator.

I've noticed that only when one of the component has changed value in the UI
of a form, then wicket calls updateFormComponentModels.
I was wondering if there is any way to force an update to the model of the
components even if none of the form components has changed value.
Thank you,
Greg
