p:pickList and the reorder event

[Dakow]

Hello PF community !
I have an issue with p:pickList and the reorder event (I use PF 12.0.5), can you help me ?

My jsf:

<p:pickList id="test" value="#{testBean.dualStrList}" var="smurf" itemValue="#{smurf}" itemLabel="#{smurf}">
    <p:ajax event="reorder" listener="#{testBean.onDataReorder}" update="@this"/>
</p:pickList>

My bean:

private DualListModel<String> dualStrList;

    @Override
    public void resetView() {
        dualStrList = new DualListModel<String>();
        dualStrList.getTarget().add("A");
        dualStrList.getTarget().add("B");
        dualStrList.getTarget().add("C");
        System.out.println("resetView");
        printTarget();
    }

    private void printTarget() {
        for (String s : dualStrList.getTarget()) {
            System.out.println(s);
        }
    }

    public void onDataReorder(AjaxBehaviorEvent event) {
        System.out.println("onDataReorder");
        printTarget();
    }

    public DualListModel<String> getDualStrList() {
        return dualStrList;
    }

    public void setDualStrList(DualListModel<String> dualStrList) {
        System.out.println("setDualStrList");
        System.out.println("source = " + dualStrList.getSource().size() + " ; was =" + this.dualStrList.getSource().size());
        System.out.println("target = " + dualStrList.getTarget().size() + " ; was =" + this.dualStrList.getTarget().size());

        this.dualStrList = dualStrList;
    }

In result, i have this behavior :

-> open my page / bean init
resetView
A
B
C
-> reorder my value "C" in the first place before "A"
setDualStrList
source = 0 ; was =0
target = 0 ; was =3
onDataReorder

my event onDataReorder is called after my setter which is emptying my list ???
thanks for your help!

Can you provide an executable example using the PrimeFaces Test project? A lot easier to debug than text.

I've found the problem, It's not working properly outside h:form, now the question is why?

Its an Input component and all input components require an <h:form> it just how HTML works 😄
