Login google-style (with redirect after ajax form refresh)

[Andreas Pardeike]

Hi,

I have a login component that updates itself via a zone. Works
great especially when you enter wrong values (server side verified).
Now, if the form successfully logs in or out, I want to refresh
the current page because it likely looks different because of the
state change.

I tried many things including a <script></script> inside the block
but since its an ajax request, JS is not executed. Or is it and
I am doing something wrong.

Any insides appreciated,
Andreas Pardeike

Here is my Login component:

<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd 
">
  <div class="kl-login-container">
    <div style="border:1px solid red">
      <t:zone t:id="loginzone" t:update="show">
        <t:delegate to="formblock" />
      </t:zone>
    </div>
  </div>
  <t:block t:id="formblock">
    <t:form t:id="loginform" class="kl-login-content"  
t:zone="loginzone">
      <t:if test="loggedIn" negate="true">
        <t:if test="isWrongLogin" negate="true">
          <p class="kl-login-head">${message:titleok}</p>
        </t:if>
        <t:if test="isWrongLogin">
          <p class="kl-login-head">${message:titlebad}</p>
        </t:if>
        <div class="kl-login-input">
          <t:textfield class="email" t:id="email"  
validate="required,regexp" />
          <t:submit class="button" value="message:login" />
        </div>
        <div class="kl-login-autologin">
          <t:checkbox t:id="autologin" />
          <span class="automessage">${message:automessage}</span>
        </div>
        <div style="clear:both" />
      </t:if>
      <t:if test="loggedIn">
        <p class="kl-login-head">${message:loggedinas} $ 
{customerDisplayName}</p>
        <div class="kl-login-input">
          <t:submit class="button" value="message:logout" />
        </div>
      </t:if>
    </t:form>
    <t:if test="refreshPage">
      Redirecting..<br />
      <script>
        alert('redirect!');
        document.location = document.location;
      </script>
    </t:if>
  </t:block>
</t:container>
