I have a code like this:
final ValueListBox<GCountry> countryList = new ValueListBox<GCountry>(new
Renderer<GCountry>() {
public String render(GCountry c) {
String s = "";
if (c != null) {
s = c.getTitleRus();
} else {
s = "Choose a country";
}
return s;
}
public void render(GCountry c, Appendable appendable) throws
IOException {
String s = render(c);
appendable.append(s);
}
});
...
countryList.addHandler(new ChangeHandler() {
@Override
public void onChange(ChangeEvent event) {
GCountry gc = countryList.getValue();
if (gc != null) {
getService().getAVCompanies(gc.getId(), null, null,
cbAvcomp);
}
}
}, ChangeEvent.getType() );
I only have a previous value (GCountry gc = countryList.getValue()) in
handler but I need a value that user choose right now
How this code can be modified?
