How to pre-populate an object to update not using DrivenModel aproach

[Tony Manello]

Hi I've been stuck with this question since two days. I got and object and i would like to update it. I'm using the object as javabean property aproach instead of using DrivenModel, so I got one action that shows all the objects and the user can choose one to update (passing the id using a hidden field from the form). Next I got an action that populate the form with the object using prepare(). Finally I got the last action that updates that object. My problem is that I can't populate the form with object data, form appears with blank properties.

Snippets:

struts.xml

 <action name="editarNota" class="presentacion.corredor.actions.EditarNota">
            <result>/vistas/corredor/EditarNota.jsp</result>
        </action>
        <action name="modificarNota" class="presentacion.corredor.actions.ModificarNota">
            <result>/vistas/corredor/ListarNotas.jsp</result>
            <interceptor-ref name="paramsPrepareParamsStack"/>
        </action>
        <action name="eliminarNota" class="presentacion.corredor.actions.EliminarNota">
            <result>/vistas/corredor/EliminarNota.jsp</result>
            <result name="redirect" type="redirect">${redirectUrl}</result>
        </action>
        <action name="listarNotas" class="presentacion.corredor.actions.ListarNotas">
            <result>/vistas/corredor/ListarNotas.jsp</result>
            <result name="redirect" type="redirect">${redirectUrl}</result>
        </action>   

Where "Editar" means "Edit", "Listar" means "List" and "Modificar" means "Update"

Here it is "ListarNotas.jsp"

 <s:iterator value="notas" >
                    <tr id="row_<s:property value="idNota"/>">
                        <td>
                            <s:form action="editarNota.action">
                                <input type='hidden' name=idNota value='<s:property value="idNota" />' />
                                <input type='submit' value='Modificar' title='Modificar' />
                            </s:form>
                        </td>
                        <td>
                            <s:form action="eliminarNota.action">
                                <input type='hidden' name=idNota value='<s:property value="idNota" />' />
                                <input type='submit' value='Eliminar' title='Eliminar' />
                            </s:form>
                        </td>
                    </tr>
                </s:iterator>  

Action "EditarNota"

   @Override
    public String execute() throws ExcepcionDeLogica {
        nota = this.logicaCorredor.getNota(idNota);
        return SUCCESS;
    } 

"EditarNota.jsp"

   <s:form method="modificarNota">
            <s:textfield label="Titulo" name="nota.titulo" />
            <s:hidden name="%{nota.idNota}" />
            <s:textfield label="Fecha de inicio" name="nota.fechaInicio" />
            <s:textfield label="Fecha de fin" name="nota.fechaFin" />
            <s:textarea label="Descricion" name="nota.descripcion" cols="40" rows="10"/>
            <s:submit value="Modificar" />
        </s:form>
        <s:a action="listarNotas">Cancel</s:a> 

And finally Action "ModificarNota"

 @Override
    public String execute() throws ExcepcionDeLogica {
        if (getNota().getTitulo().length() > 0  && getNota().getDescripcion().length() > 0) {
            this.logicaCorredor.modificarNota(getNota());
        }
        return SUCCESS;
    }
    private int idNota;

    public int getIdNota() {
        return idNota;
    }

    public void setIdNota(int idNota) {
        this.idNota = idNota;
    }
private Nota nota;

    public Nota getNota() {
        return nota;
    }

    public void setNota(Nota nota) {
        this.nota = nota;
    }

    public void prepare() throws Exception {
        nota = this.logicaCorredor.getNota(getIdNota()); //Retrieve object from DB
    }

   

Any suggestion or tip? What am I doing wrong?

The problem is that the form is not prepoluted, I've tried using <s:hidden> inside the form but it is not working.

The secuence I follow is:

1 - From a jps with a list of objects I use a <s:form action=edit.Action> with a hidden field which contains the object's id to update.

2 - An edit form with "prepopulated data" inside <s:form action=updateAction> with a hidden field with the id. (This action retrieves the object using id inside execute() method and returns SUCCESS.

I get blank fields in the edit form.
I don't know what I'm doing wrong.

Any suggestion?

Hi,
I solved the problem it was my fault I forgot to declare the object I want to prepopulate, and finally I Used ModelDriven and it works ok!
