You could extract a method of that monster :)
For example private boolean selectedCountryHasRegions(), or
even professionalInfo.getCountryWork().hasRegions(getRegionDao());

And instead of testing for size == 0 call isEmpty(), and the
formatting here is kind of unconventional as well (Eclipse
3.3 has the nice new possibility of adding Save actions such
as reformat code).

regionWork = new DropDownChoice(...) {
@Override
public boolean isEnabled() {
return selectedCountryHasRegions();
}
or it it doesn't work
regionWork = new DropDownChoice(...) {
@Override
public void onBeforeRender() {
super.onBeforeRender();
setEnabled(selectedCountryHasRegions());
}
Best wishes,
