Hi,
i've linked a List Object to an Arraylist contained in the model in this
way:
bindingContext.bindList(SWTObservables.observeItems(_listGen re),
BeansObservable.observeList(Realm.getDefault(), model,
"listGenre"), null, null);
_listGenre is the List object
in the model i have put
public ArrayList<String> getListGenre() {
return listGenre;
}
public void setListGenre(ArrayList<String> listGenre) {
ArrayList<String> old = listGenre;
this.listGenre = listGenre;
changeSupport.firePropertyChange("listGenre", old, listGenre);
}
In this way no items are added to the arrayList when the _listGenre is
filled with elements. What's wrong?
thanks
Christian
