[JSF 2.0] re-render a dataTable with Ajax ?

[Celinio Fernandes]

Hi,
I found several posts dealing with my problem :

None gives answers unfortunately.

My problem is simple : I have a dataTable which contains a list of products, the last column has a link to delete a product.

<h:form  id="Form1">
  
 <h:dataTable value="#{myBean.myList}"  id="dataTable1" ...>
 <h:column>
  ...
 </h:column>
 ...
  <h:column> 
 <h:commandLink value="update"  action="#{myBean.delete}" >
                   <f:ajax execute="@this" render=":Form1:dataTable1"  />
                <f:param name="id" value="#{product.productid}"/>
 </h:commandLink>            
 </h:column> 
    </h:dataTable>
   
 </h:form>

My delete method in my managed bean looks like this :

 public void delete() {
        FacesContext context = FacesContext.getCurrentInstance();
        Map<String, String> params = context.getExternalContext().getRequestParameterMap();
        String idNumber = params.get("id");
        myEJB.delProduct(idNumber);
    }

It deletes the product. However it does not re-render the dataTable. What am i missing ?
What value should the render attribute be set to in that case ?

Thanks in advance for helping.

Why can't you use ajax4jsf? It is very easy to use these kind of things with that. You can assign an id(say dataTableId) to your datatable and on click of the commandlink call an a4j function and onComplete you can reRender the dataTableId.
