Hello!
I have a list with objects I've got from "backend-side". Every object has a
getSort() method, which returns an integer value. I've never worked with
Comparator before, but I tried like the following:
public List<Objecttype> getObjectListe() {
List<Objecttype> sortedList = model.getObjects();
Collections.sort(sortedList, new Comparator<Objecttype>() {
public int compare(Objecttype o1, Objecttype o2) {
// compare the o1.getSort() value with o2.getSort() value here
}
});
return sortedList;
}
And this is the error I got:
[ERROR] Uncaught exception escaped
java.lang.UnsupportedOperationException: null
at
com.incowia.tkbase.unternehmenspflege.core.client.BaseReferenceList.toArray(BaseReferenceList.java:166)
at java.util.Collections.sort(Collections.java:158)
What have I to do, to sort my list?
