flow problem with reload button

[Antonio Fiol Bonnín]

Hello,

I am having strange problems (described below) when hitting the "reload" button on my browser when displaying form B in scenario described below. Could anyone please help me understand why?

I am using a 2-form approach to editing an XML file, one for a first level view and a deeper detail editing view.

Form "A" only contains a repeater with a "nombre" widget for each row, plus all the necessary widgets for deleting selected rows.
It also has a submit called "nuevo" (=Add new, see below for js code managing it), a standard HTML submit button, and an edit submit button on each row.

Example:
[Delete selected] [Add new] [Save changes]
[X] [Edit] Name1
[X] [Edit] Name2
[X] [Edit] Name3
[X] [Edit] Name4

Form "B" is bound to the same XML file, but with more fields and attributes mapped to form widgets, but it only maps a certain part of the XML.

Example:
Name: [Name1]
E-mail: [[EMAIL PROTECTED]]
[Save changes]

So the binding for B is dynamically generated by a pipeline.

The flow should be
A->B->A if "Edit" or "Add new" are used.
A->A if "delete selected" or "save changes" are used.

function editarRestaurantes() {
    // Keep important things in vars, as they will be lost from cocoon.parameters
    var formDefinitionA = cocoon.parameters["form-definition-a"];
    var formDefinitionB = cocoon.parameters["form-definition-b"];
    var bindingURIA = cocoon.parameters["bindingURI-a"];
    var bindingURIBPrefix = cocoon.parameters["bindingURI-b-prefix"];
    var saveURI = cocoon.parameters.saveURI;
    var saveXSLT = cocoon.parameters.saveXSLT;
    var displayPipelineLista = cocoon.parameters["displayPipeline-a"];
    var displayPipelineFicha = cocoon.parameters["displayPipeline-b"];

    var formLista = null;
    var formFicha = null;
    var formB = null;

    var datos = leerDatos(cocoon.parameters.loadURI); // Read the XML file and store into "datos"

    formLista = createForm(formDefinitionA, bindingURIA, datos);

    while(true) {

         // display form A
         formLista.showForm(displayPipelineLista);

// *********************************
// If I hit reload when form B is displayed, execution is resumed here, but formLista is undefined
// Why is it "null"? Shouldn't it be restored to the previous value because of my hitting "Reload".
// *********************************
      
        var submitWidget = formLista.getWidget().getSubmitWidget();
        var idRestaurante = "";

        // Did the user not click the "Save changes" button?
        if(submitWidget!=null) {
            cocoon.log.info(submitWidget);
            // Did the user click "Add new"?
            if(submitWidget.id=="nuevo") {
                // To add a new record, we ask the repeater to do so.
                var repeater = submitWidget.parent.lookupWidget('restaurantes');
                repeater.addRow();
                // New record is last, so get the repeater size
                idRestaurante = repeater.size;
            } else {
                // Clicked "Edit", ... which row?
                idRestaurante = submitWidget.getParent().lookupWidget('id').value;
            }
            formLista.save(datos);
            formLista = null;

            // Prepare form B, using the ID for the new or edited record
            formFicha = createForm(formDefinitionB, bindingURIBPrefix+idRestaurante, datos);

// ***********************
// Form B is displayed on next line
// ***********************

            formFicha.showForm(displayPipelineFicha);
            formFicha.save(datos);
            formFicha = null;

            formLista = createForm(formDefinitionA, bindingURIA, datos);
        } else {
            formLista.save(datos);
        }
        grabarDatos(saveURI, saveURI+".tmp", saveXSLT, datos);

    }
}

function createForm(definition, binding, datos) {
    var form = new Form(definition);
    if (binding != null) {
        form.createBinding(binding);
    }
    form.load(datos);
    return form;
}



Thank you very much for any hint, and sorry for the long e-mail. I tried hard to make it shortest possible.
