Try this:
List choices;
if(<empty_condition>){
choices = new ArrayList();
}
else{
choices = ....
}
DropDownChoice d = new DropDownChoice("drop", new
PropertyModel(this,"drop"), choices) {
protected void onComponentTagBody(final MarkupStream
markupStream, final ComponentTag openTag)
{
Object list =getChoices();
if(list instanceof List){
int size = ((List)list).size();
if(size > 0){
super.onComponentTagBody
(markupStream,openTag);
}
else{
replaceComponentTagBody(markupStream, openTag,
new AppendingStringBuffer());
}
}
else{
super.onComponentTagBody(markupStream,openTag);
}
}
};
