Button action fires on each page refresh

[msantana]

Hi! I have a problem, when i try to fire the action of a button. The action fires each time i refresh the page.
Anyone who has a tip?
Thanx in advice!

The CarritoBean:

@Name("carrito")
@AutoCreate
@Scope(ScopeType.SESSION)
@Restrict("#{identity.loggedIn}")

public @Stateful class CarritoBean implements Carrito {

private Double importeTotal=0.0;
     
    @DataModel
    private List<Producto> productosAComprar;
     
    public Double getImporteTotal() {
          return importeTotal;
     }

     public void setImporteTotal(Double importeTotal) {
          this.importeTotal = importeTotal;
     }
    
    @Remove @Destroy
    public void destroy() {}
    
    public void addProductoAComprar(){
         try {
              Long productoId = new Long(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("producto"));
              if(productosAComprar==null){
                   productosAComprar = new LinkedList<Producto>();
              }
              InitialContext ic = new InitialContext();
              ProductosService productosService = (ProductosService)ic.lookup("SGAF-ear/ProductosServiceBean/remote");
              Producto producto = productosService.getProductoById(productoId);
             productosAComprar.add(producto);
             importeTotal+=producto.getImporte();
          } catch (Exception e) {
               e.printStackTrace();
          }
    }
    
    public void removeProductoAComprar(){
         /*productosAComprar.remove(producto);
         importeTotal=importeTotal - producto.getImporte();*/
    }
     
}

The code in the xhtml:

<rich:column styleClass="action">
     <f:facet name="header">Acciones</f:facet>
       <s:button value="Comprar"
               id="comprar"
            image="#{request.contextPath}/img/fam/basket_add.png"
            title="Comprar"
            action="#{carrito.addProductoAComprar()}"
            reRender="importeTotal">
          <f:param name="producto" value="#{producto.productoId}"/>
     </s:button>
 </rich:column>

hello,

just send a redirect as response instead of the result page.

Sorry but i´m new on this. But You are saying on the return of the method addProductoAComprar?
Or where and how, i must do that.
Sorry about my ignorance!, and thanx!!!

       <s:button value="Comprar"
               id="comprar"
            image="#{request.contextPath}/img/fam/basket_add.png"
            title="Comprar"
            action="#{carrito.addProductoAComprar()}"
            reRender="importeTotal">
          <f:param name="producto" value="#{producto.productoId}"/>
     </s:button>
 

Can you try to change your action from

carrito.addProductoAComprar()

to

carrito.addProductoAComprar

I think s:button is evaluating the method on the render phase.

[msantana]

Thank you very much!!! I will try that if i have news i let you know.

[msantana]

Nop, it doesn´t work. I changed:
carrito.addProductoAComprar() to carrito.addProductoAComprar, without success. I press the button, and then i refresh the page, and it fires the event again, adding the same product again.

Other ideas?

Hi,

one kind of redirect:
Type in pages.xml

<page view-id="/your_view.xhtml">
        <navigation>
            <rule if="#{carrito.addProductoAComprar}">
                <redirect view-id="/your_resulting_view.xhtml"/>
            </rule>
        </navigation>
    </page>

Yes i know. but i dont want to do that, i put a rerender on the button, so a inputText is rerender by ajax.
My problem is: I press the button, it fires the action {carrito.addProductoAComprar}. Then it makes all good. But after that if i refresh the page with Ctrl and F5, then the same product i have added, is added again.

Thanx for all your support, but anyone who has another tips?

Hi,

if your're using s:button, the whole page will be new rendered. (isn't it?)
In this context, what is the sense of ajax rerendering?

BJ

[msantana]

Ok! you´re right!, and that´s a good point i miss.
So correct me if i am wrong, but i have to put a link then, haven´t i?

Thanx for all your support man.

no, a link has the same behaviour!
You got to decide: If you want to do ajax, use a4j:commandButton. But i would prefer s:link or s:button and redirect as mentioned.

Its generally a good idea to understand the meaning of the used tags. What is the result in HTML-Page on the browser? What data are transferred between client and server?

I have two grids where i click a button(which is an image) on one row of the first grid and it passes the row to the athoer grid.
So i made, that button on a column of the first row who passes a param which is the productId.
So on the server i, look for that product(passes on request) and added to the collection which is the dataModel of the other grid.
Then the datatable makes the render of the other grid when action is fire.
I don´t want to refresh the whole page each time i add a row.
Maybe you have better ideas of that?

Thanx!

[msantana]

Thanxxxxxx!!!!!!
I try with the a4j:commandButton and all gets right!!!
The only thing is not working is that the a4j:commandbutton is not showing the image. i want the button were an image.
But seams like something is wrong but the most important thig wa sloved, thank to you.

You are the best guys!
