I'm not finished investigating this yet, but my preliminary findings
indicate that the solution (at least in my case) is to call
dropdown.getModelObject() instead of dropdown.convertInput(). In the use
cases I've tested so far, getModelObject() returns the correct value.

Subject: RE: DropDownChoice in FormComponentPanel
Simplest way I can think of is something like:
@Override
protected void onBeforeRender() {
if(isValid()) {
dropDown.getFormField().setDefaultModel(getDefaultModel());
}
...
super.onBeforeRender();
}
@Override
protected void convertInput() {
if(dropdown != null) {
setConvertedInput(dropDown.getConvertedInput());
}
...
}
But it really depends on what your FormComponentPanel is wrapping and how
you share its model among the child components.
Refer to the Wicket Users Guide section 1.8 "Creating comples form
components with FormComponentPanel":
http://wicket.apache.org/learn/books/freeguide.html
Or search the wiki pages:

Subject: DropDownChoice in FormComponentPanel
I have a FormComponentPanel with both string fields & DropDownChoice
controls. How do I get the drop downs' current selections from inside my
override of convertInput()?
I can get the string fields' values by calling the fields' convertInput()
methods, but when I call convertInput() on the drop downs, I get the
ORIGINAL value of the drop down, not the CURRENT value. I'm using Wicket
1.4.17 (version imposed by our corporate framework).
I've looked at several different Wicket references, including Wicket in
Action, Apache Wicket Cookbook & the new online free Wicket guide, but
could
not find this issue discussed.
