Actually, I get a
[ERROR] ExceptionHandler
org.apache.tapestry.runtime.ComponentEventException: No object of type
org.apache.tapestry.PageRenderSupport is available from the
Environment. Available types are
org.apache.tapestry.ValidationTracker,
org.apache.tapestry.services.ComponentEventResultProcessor,
org.apache.tapestry.services.FormSupport,
org.apache.tapestry.services.Heartbeat. [at classpath:se/fsys/klubb/
components/login/Login.tml, line 10, column 72]
when I change
if(isLoggedIn())
{
_session.setCredentials(null, true);
_access.clearAutoCredentialsCookie();
_refreshPage = true;
}
to
@Environmental
private PageRenderSupport _pageRenderSupport;
...
if(isLoggedIn())
{
_session.setCredentials(null, true);
_access.clearAutoCredentialsCookie();
_pageRenderSupport.addScript("alert('redirect');'");
}
I really would love to see an improvement on
@OnEvent(component = "loginform", value = "success")
public Object successFromLoginForm()
so the type of action is determined by the object type I return. It
would follow the style of a normal listener so I could return a string
to redirect, a page instance to go to that page, a Block to render the
ajax response or (and that is my favorite) 'null' to just refresh the
zone so I don't have to hack around this as in the example below.
Howard?

Hello,
To add Javascript after an action on the server side, you can use
the PageRenderSupport class.
Actually, this may work for Ajax and non-Ajax request.
To inject this class in your component :
@Environmental
private PageRenderSupport _pageRenderSupport;
Hope it helps.
Christophe.

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