Form submit always redirects to the action page instead of the target div

[Jose A. Corbacho]

Hi all,
All the forms in my application redirect to the the action associated
instead of the target div.

I'm using Struts 2.1.6

Here is the code:

<s:form id="loginForm" namespace="/" action="Login" method="post" >
   <s:textfield name="name"  />
    <s:submit targets="contentDiv"/>
</s:form>

I also try with
<s:submit targets="contentDiv" notifyTopics="show_contentDiv_topic"/>

having

<sx:div id="contentDiv" listenTopics="show_contenDiv_topic">
</sx:div>

Doing it using  <sx:a> works but it's not what I'm looking for.

<sx:head/> is defined in the pages

Thanks
