Re: Easy Way to create a select model?
Hi Andy,
I find the easiest way to populate a select list is just to pass it a Map of
values. Something like the following:
public Map getMonthsModel()
{
Map model = new LinkedHashMap();
model.put(1, "Jan");
model.put(2, "Feb");
model.put(3, "Mar");
return model;
}

Unfortunatly this interface has some more functions to implement. My
point is: isn't this all a bit to complicated? Just in order to show a
model like the one I was referring to in my first mail?
@Override
public Map getAttributes() {
// TODO Auto-generated method stub

}
@Override
public String getLabel() {
// TODO Auto-generated method stub

@Override
public Object getValue() {

Re: Easy Way to create a select model?
just a implementation of the interface with a constructor that accepts the
value and the label
public class SimpleOptionModel implements OptionModel
{
private final T value;
private final String label;
public SimpleOptionModel(T value, String label)
{
this.label = label;
this.value = value;
}
