Java Development Tools

Hello Folks.

I have Jdeveloper 11G 11.1.1.7.0

I will try to explain very detailed my issue, with a short example of a master-detailed table that i can't retrieve the ID... it stop working unexpected and unfortunately i can't get ride of it.

Many errors i encounter with ADF but now all seems to be fine and it doesn't work. First of all i have a table call Robos and a detail table call Poliza.

If i run the module the data shows correctly but if i try to manage the data with a invokeAction pointed to a data control bean function call RepDocArc() with refresh set to renderModel or even any other one.

I attach an image of the Module running with the respect called id (here it works well):

In the application that is a short one and mentioning i tried every Refresh Option available in the iterators, also i set the ChangeEventPolicy to PPR without success:

The RepDocArc function that autoloads when the page open is:

public void RepDocArc(){

    FacesContext ctx = FacesContext.getCurrentInstance();

    Application app = ctx.getApplication();

    ValueBinding bindCount = app.createValueBinding("#{viewScope.Counter}");

    Counter counter = (Counter) bindCount.getValue(ctx);

    BindingContext bindingctx = BindingContext.getCurrent();

    BindingContainer bindings = bindingctx.getCurrentBindingsEntry();

    DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;

    DCIteratorBinding dciter = bindingsImpl.findIteratorBinding("RoboView1Iterator");

    ViewObject voRoot =dciter.getViewObject();

    ValueBinding bindActividades = app.createValueBinding("#{pageFlowScope.Actividades}");

    Actividades actividades = (Actividades) bindActividades.getValue(ctx);

    if (counter.getCount() == 0){

        voRoot.setWhereClause("NUMEROREPORTE = '04170285448'");

        voRoot.executeQuery();

        DCIteratorBinding dciter2 = bindingsImpl.findIteratorBinding("PolizaView1Iterator");

        Row row4 = dciter2.getCurrentRow();

        System.out.println(row4.getAttribute("Id1").toString()); //here i got the nullpointer exception.

        counter.setCount(counter.getCount() + 1);

    }

}

Any idea? i am running out of patient as everything has been tried .

Best regards.

Jorge.
