Struts 2: Succes not redirecting when using Ajax Validation

[Emili Calonge]

I have a simple application, a form for creating users. The .java has two methods, the execute and an action for fetching a list of poblations.
So first I call to the fetch method wich gets the list and redirects to the form. The when I submit the form, the validation works perfectly, but when either an error happens or the action succeeds, nothing happens. I just get the destination page as an ajax message when the expected result would be a redirection.
So my configuration is as follows:

    
<action name="registreUsuari" class="accions.publiques.registreUsuari">
            <interceptor-ref name="jsonValidationWorkflowStack" />
            <result name="input">/public/registreUsuari.jsp</result>
            <result name="success">/public/index.jsp</result>
            <result name="error">/public/error.jsp</result>
        </action>
        <action name="registreUsuariPrepare" method="buscarPoblacions" class="accions.publiques.registreUsuari">
            <result>/public/registreUsuari.jsp</result>
        </action>

So first I call the registreUsuariPrepare action, then I get redirected to ublic/registreUsuari.jsp which contains the form, and when I submit the form, if the success or the error results are returned, I don't get redirected, I just get the contents of index.jsp or error.jsp as an Ajax response.
How can I avoid that and get redirected, what am I doing wrong?

My java is this:

  
@Validations(
requiredStrings={
    @RequiredStringValidator(fieldName="usuari.nom", type = ValidatorType.FIELD, message="error.campBuit")})

public class registreUsuari extends ActionSupport 

@Override
    public String execute() 
    {
     try
        {
            dao.insert(usuari);
        }
        catch(Exception ex){
            return ERROR;
        }
        return SUCCESS;
    }
@SkipValidation
    public String buscarPoblacions(){
        llistaPoblacions = dao.executeFinder("Poblacio.findAll");
        return SUCCESS;
    }
 

I've tried adding

   
<param name="excludeMethods">error,success</param>
 

to the jsonValidationWorkflowStack, but it also doesn't work. I think it has to be something with this stack, but all the examples I've seen seem to work fine just like this.
Thanks!

I ran into a similar issue when using the interceptor-ref in the action definition. What I had to do is add other interceptor references.
Try the following:

<action name="registreUsuari" class="accions.publiques.registreUsuari"> 
     <interceptor-ref name="servlet-config"/>
     <interceptor-ref name="jsonValidationWorkflowStack" />  
     <result name="input">/public/registreUsuari.jsp</result>  
     <result name="success">/public/index.jsp</result>  
      <result name="error">/public/error.jsp</result>  
 </action>

@Richard: servletConfig is already included in the JSON interceptor stack.

@Emili: Is this an Ajax form submit? You don't actually say.

[Emili Calonge]

@David Newton: Yes, I'm using ajax submit with the struts2-jquery library. The submit looks like this:

    <sj:submit validate="true" targets="result" button="true" value="Submit" />
