Really? That's not possible in an 1.4-based application, IMHO.
FormComponentPanel is a FormComponent, i.e., it participates in
conversion, validation, and update Model. When that
FormComponentPanel has an associated model, e.g., a
CompoundPropertyModel, its getInputAsArray() will return null, null
will be stored as convertedInput, and updateModel() will set the
CompoundPropertyModel's object to that null value.
When sub-widgets of a FormComponentPanel do all the work necessary,
and the FormComponentPanel has a model of its own, I often override
updateModel() to be an empty method, to prevent the behavior named
above from happening.
Best,
Joachim
