Okay. Just one more question.
I have a domain model (HrpBbheerk) which contains a Short column. I would
like to fill this via Select2Choice.
I read the select2-examples but not able to get rid it.
So the steps I took.
1. Fill my hepar5list list from my domain model (HrpBbhepar5). This contains
couple of columns but I only need for two. One for value and one for
description. If possible I don't want to create another wrapper class just
for this case.
2. Create a form, added a model (HrpBbheerk)
3. Added a new Select2Choice to the form with that Short column mentioned
above.
Snippets:
...
fillHepar5(); // step 1
HrpBbheertk heertk = fillHeertk();
IModel model=new CompoundPropertyModel(heertk);
sform.setModel(model); // step 2
Select2Choice dimelemert = new Select2Choice("dimelemert",new
PropertyModel(sform.getModel(),"dimelemert"),new Hepar5Provider()); // step
3
......
private static List<HrpBbhepar5> queryMatches(String term, int page, int
pageSize) {
List<HrpBbhepar5> result = new ArrayList<HrpBbhepar5>();
term = term.toUpperCase();
final int offset = page * pageSize;
int matched = 0;
for (HrpBbhepar5 hepar5 : hepar5list) {
if (result.size() == pageSize) {
break;
}
if (hepar5.getDertekmegnev().toUpperCase().startsWith(term)) {
matched++;
if (matched > offset) {
result.add(hepar5);
}
}
}
return result;
}
public class Hepar5Provider extends TextChoiceProvider<HrpBbhepar5> {
@Override
protected String getDisplayText(HrpBbhepar5 choice) {
return choice.getDertekmegnev();
}
@Override
protected Object getId(HrpBbhepar5 choice) {
return choice;
}
@Override
public void query(String term, int page, Response<HrpBbhepar5>
response) {
response.addAll(queryMatches(term, page, 10));
response.setHasMore(response.size() == 10);
}
@Override
public Collection<HrpBbhepar5> toChoices(Collection<String> ids) {
ArrayList<HrpBbhepar5> hepar5idlist = new
ArrayList<HrpBbhepar5>();
Iterator it = hepar5list.iterator();
while (it.hasNext()) {
HrpBbhepar5 h = (HrpBbhepar5) it.next();
hepar5idlist.add(h);
}
return hepar5idlist;
}
}
.....
It complains that java.lang.Short cannot be cast to
hu.xxx.model.HrpBbhepar5.
Please let me know what should I do.
thnx., Sandor
