I find that using the following variable naming convention helps a lot.

public MyClass myObjectItem; // used for binding to item binding
private MyClass _myObjectSelection; // used for binding to selection binding

public MyClass myObjectSelction() { return _myObjectSelection};

public void setMyObjectSelection(MyClass myObject) { _myObjectSelection = myObject );

private NSArray<MyClass> _myObjects; // for binding to list of the component
public NSArray<MyClass> myObjects {
if (_myObjects == null) {
_myObjects = MyClass.fetchAllMyObjects(editingContext(), MyClass.SORT_ATTRIBUTE.ascs());
}
return _myObjects;
}

// if there is an AjaxObserveField action

public WOActionResults selectedMyObject() {
// do what you need to do here.
return null;
}

Hope this helps.

Hi Stefan,

I don't use selectedMotClefs because the value on selected item is NULL so I get javaNullPointerException in lesMotsClefs1() method with selectedMotClefs in parameter, it's the reason why I stuck on this problem.

Thanks for your help

Hi Raymond,

that sounds like you are using the value bound to "item". Try using selectedMotClefs and selectedMotClefs1;

Hi All,

I try to create a cascading autocompletion but I have a big problem retrieving the id of the selected item. In fact when I select the data, the id that I get is the last item in the list. What I mean is that the id of the selected item never changes and I am completely stuck.

Example

HTML :

<wo name = "autoCompAOF1"><webobject name = "motClefsAutoComplete1" /></wo>
<webobject name = "autoComp2AUC">
                <div id = "searchForm">
                  <webobject name = "motClefsAutoComplete2" />
                </div>
</webobject>

WOD :

motClefsAutoComplete1 : AjaxAutoComplete {
    id = "auto1";
    list = matchMotcClefs;
    item = motClefsRepetition;
    displayString = .motClefsRepetition.refidxval;
    selection = selectedMotClefs;
    value = motClefs;
}

autoCompAOF1 : AjaxObserveField {
    id="autoCompAOF1";
    fullSubmit = true;
    elementName = "span";
    action = "">     updateContainerID = "pop2";
}

motClefsAutoComplete2 : AjaxAutoComplete {
    id = "auto2";
    list = matchMotcClefs1;
    item = motClefsRepetition1;
    displayString = motClefsRepetition1.refidxval;
    selection = selectedMotClefs1;
    value = motClefs1;
}

JAVA :

// AutoCompletion1 data list
    public NSArray<EORefidx> matchMotcClefs() {
        if(matchMotcClefs == null){
            if(motClefs == null){
                matchMotcClefs = null;
            } else {
                matchMotcClefs = EORefidx.REFIDXVAL.containsAll(motClefs).filtered(lesMotsClefs());
            }
        }
        return matchMotcClefs.immutableClone();
    }

   // AutoCompletion2 data list which depends to selected item in AutoCompletion1
    public NSArray<EORefidx> matchMotcClefs1() {
        if(matchMotcClefs1 == null){
            if(motClefs1 == null){
                matchMotcClefs1 = null;
            } else {
                matchMotcClefs1 = EORefidx.REFIDXVAL.containsAll(motClefs1).filtered(listMotclefs1);
            }
        }
        return matchMotcClefs1.immutableClone();
    }

private NSArray<EORefidx> lesMotsClefs(){
        if(listMotclefs == null){
            listMotclefs = EORefidx.fetchGetMotsClefsParents(session().defaultEditingContext());
        }
        return listMotclefs;
    }

    public NSArray<EORefidx> lesMotsClefs1(){
        if(listMotclefs1 == null){
            listMotclefs1 = EORefidx.fetchGetMotClefs(session().defaultEditingContext(),Integer.valueOf(motClefsRepetition.primaryKey()));
        }
        return listMotclefs1;
    }

    public WOActionResults refreshPop2() {
        if (motClefsRepetition() != null) {
            lesMotsClefs1();
        }

        return null;
    }

Thank you for your help
