Hello,

I have a problem with a listbox, when the listbox has more than 100 items it takes too long to add new items and show them.

This is the java code that adds new item to the listbox:

private List<DetalleRequerimiento> listarequerimientodet;

@Command("agregarDetallle")
@NotifyChange("listarequerimientodet") 

public void agregarDetallle(){        

   DetalleRequerimiento dd= new DetalleRequerimiento();
   if(this.requerimientodet.getIdcentrocostosap()!=null && this.requerimientodet.getIdcentrocostosap().getPrccode()!=null)
        dd.setCentrocostosap(this.requerimientodet.getIdcentrocostosap());
   else
        dd.setCentrocostosap(null);

   this.listarequerimientodet.add(dd);

}

listarequerimientodet is a List asociated to the listbox for rendering the items, this is the code in the zul file:

<listbox id="listadet" hflex="1" vflex="1" model="@load(vm.listarequerimientodet)"  checkmark="true" multiple="true" mold="paging" pageSize="250"   >

<listhead  sizable="true">

    <listheader align="center" hflex="min">

                    <listfooter />


</listfoot>
</listbox>

When i click the button that calls the function 'Agregar Detalle' and my listbox already has more than 100 items it takes too long to show the new item. I need it to be way faster:

Please help me, it would be very useful for my testing
