What about this:
Form myForm = new Form("form");
add(myForm);
final Component myComponentToFocus = ...;
myForm.add(myComponentToFocus);
final ModalWindow modalWindow = new ModalWindow("modal") {
@Override
public void show(AjaxRequestTarget target) {
super.show(target);
target.focusComponent(myComponentToFocus);
}
};
add(modalWindow);
modalWindow.setContent(myForm);
AjaxLink opener = new AjaxLink("link") {
@Override
public void onClick(AjaxRequestTarget target) {
modalWindow.show(target);
}
};
add(opener);
