Hi again,
I realized that parts of the code were removed, so I post this message again,
this time using HTML.
Sandro and Roger, I thank you for your answers.
I think that I have oversimplified my question. Actually, my bean has a list of
keys, in my form there is one checkbox for each value that could be in the
list. I would like to check all the checkboxes which keys are in the list and
get the modifications back to my bean via the context. I have written this
class :
private static class CheckboxMapping implements Button.ButtonDataBindMapping {
private static final Set> typesPlat = new HashSet>();
private final Checkbox cb;
private final Key key;
public CheckboxMapping(Checkbox cb, Key key) {
this.cb = cb;
this.key = key;
}
@Override
public Object toButtonData(Object value) {
if (((List>) value).contains(key))
cb.setSelected(true);
return cb.getButtonData();
}
@Override
public Object valueOf(Object buttonData) {
if (cb.isSelected())
typesPlat.add(this.key);
return new ArrayList>(typesPlat);
}
}
I set the setButtonDataBindMapping with a new instance of this class with the
checkbox and the key as parameters, then I set the setButtonDataKey with the
name of the bean list of keys.
It is ugly, but it works. If there is a smarter solution, I would be glad to
read it.
Bye...
