Hi, thanks for the tip.. unfortunately , I tried this, (a shorter version at
least..)
add( new DropDownChoice("userProfile.city",
new PropertyModel(this.getModel(), "userProfile.city"),
new LoadableDetachableModel() {
@Override
protected Object load() {
return sysMultivaluesProvider.getMVList("CITY");
}
}
)
);
but the problem is the same the selected value is persisted into the
database but when I edit the record the value is not "selected" in the
dropdown.. any clues?
I'm obviously missing something!!
TIA
