DropDownChoice model is not updated when
wantOnSelectionChangedNotifications is overriden
Hi,
I want to make a filter to update a table according to selected user.
I am filling a hashmap to retrieve some data from database. To accomplish
that
I overrided "wantOnSelectionChangedNotifications" method. But the problem
is;
when I choose the user1, the model value is updated as it is exptected and
hashmap
is updated. But after that I am choosing user2 but neither the model value
nor hashMap is not updated
and the selectbox is still showing user1..
I put a a breakpoint into propertyModel constructer but it didnt stop there
in debug mode.
Any idea?
Thanks
private HashMap<String, String> criteriaMap= new HashMap<String, String>();
Criteria criteria = new Criteria();
List userFilter=new ArrayList();
userFilter.add("user1");
userFilter.add("user2");
add(new DropDownChoice("selectByUser", new PropertyModel(criteria,
"userCriteria"),userFilter) {
@Override
protected boolean wantOnSelectionChangedNotifications() {
criteriaMap.put("user",criteria.getUserCriteria());
return true;
}
});
public class Criteria implements Serializable{
private String userCriteria;
public String getUserCriteria() {
return userCriteria;
}
public void setUserCriteria(String userCriteria) {
this.userCriteria = userCriteria;
}

yes, a new instance of the page will be created.

You should provide a quickstart, so we are able to check what you're
doing differently.

Yes I checked the FormInput example..The only difference is that example has
custem dropwdown component which stated in the same class..Also it uses the
following in onSelectionChanged method..
// force re-render by setting the page to render to the bookmarkable
// instance, so that the page will be rendered from scratch,
// re-evaluating the input patterns etc
setResponsePage(FormInput.class);
When I put this line into my code, it renders the all page and all the model
values are reset to default including my selectbox model value...is this
normal?
The point is, I used dropdown component hundred times in the forms and didnt
face any problem like this.
Because I did not need to override any methods to do some job after
selecting something..This is the first time I didnt attach this component to
a form...If I remove these two overriden methods, selectbox model value is
updated in all selections accordingly..

I think I am doing something wrong or there is a bug..newSelection is not
contain the new selected user..like model value..
If I dont override any methods, selectbox model value is updated as it is
expected..
But the the both of them always show the first selection...
new PropertyModel(criteria, "userCriteria") and
protected void onSelectionChanged(Object newSelection)

Ok I am overriding the both methods but still cannot update the
userCriteria..It always contains the
the value that I selected first..
new PropertyModel(criteria, "userCriteria")
The whole code is as following;
public class ListQuestionsPage extends AdminBasePage {
@SpringBean
UserDao dataDao;
private HashMap<String, String> criteriaMap= new HashMap<String, String>();
Criteria criteria = new Criteria();
public ListUsersPage() {
final LoadableDetachableModel data= new LoadableDetachableModel() {
@Override
protected Object load() {
List<Data> dataArrayList = dataDao.findAll();
return dataArrayList;
}
};
final WebMarkupContainer listContainer = new
WebMarkupContainer("listContainer");
add(listContainer);
List userFilter=new ArrayList();
userFilter.add("user1");
userFilter.add("user2");
add(new DropDownChoice("selectByUser", new PropertyModel(criteria,
"userCriteria"),userFilter) {
@Override
protected boolean wantOnSelectionChangedNotifications() {
return true;
}
@Override
protected void onSelectionChanged(Object newSelection) {
criteriaMap.put("user",criteria.getUserCriteria());
}
});
PageableListView userList = new PageableListView("userList",data
,10) {
@Override
protected void populateItem(final ListItem item) {
final User user = (User) item.getModelObject();
item.add(new Label("id", Long.toString(user.getId())));
item.add(new Label("user", user.getUser().getUsername()));
item.add(new Label("details", user.getDetails()));
}
};
listContainer.add(userList);
add(new PagingNavigator("navigator",questionList));
}
}

See org.apache.wicket.examples.forminput.FormInput, you need to override
both methods.

Thanks for the quick response Sven...But eclipse gives error for the code
you
suggested
I changed it as below;
@Override
protected void onSelectionChanged(Object criteria) {
criteriaMap.put("user",((Criteria)
criteria).getUserCriteria());
}
But using onSelectionChanged does not render the page..I need to reload
table data from database
according to the choice is made in selectBox..Because of that I used
"wantOnSelectionChangedNotifications"
final LoadableDetachableModel data= new LoadableDetachableModel() {
@Override

List<Data> dataArrayList = dataDao.findAll();
return dataArrayList;
