Visit Object and multiple frames
Hi,
I'm working on a multiple frame application, the home page is a frameset
that loads 5 frames.
The home page is a protected page so I implemented the pageValidate and if
the user is not log in I'm throwing PageRedirectException to the login page.
The first time the user login everything works fine, I see that the user is
not login, I redirect him to the login screen and after that load the home
page with all the frames.
The problems start When the user logout using the logout link and try to
login again. I get a very strange behavior:
1 The user get the login screen and performs the login
2 After the user is login I start to load the home page with all the frames.
3 For some reason each frame gets each own new copy of the visit object with
all the fields initialize to their defaults which cause me to redirect the
user to the login page again.
When running in debug mode using the debugger the application behave
normally what make me think that this is a race condition.
Any Suggestions
Thanks Simon
the home page template is

Re: Visit Object and multiple frames
Posted by Jim Frederic <ji...@isogen.com>.
I believe the problem is that you are killing the session and remaining
on the server to go back to the login page. Instead, try a client-side
redirect, like this:
public void logout( IRequestCycle cycle )
{
FMCEngine engine = (FMCEngine)getEngine();
Home home = ( Home ) cycle.getPage( "Home" );
engine.logout();
// throw new PageRedirectException( home );
cycle.getRequestContext().getSession().invalidate();
// go back to the beginning.
try {
String uri = cycle.getRequestContext().getRequestURI();
cycle.getRequestContext().redirect(uri);
} catch (IOException e) {
// Log this
}
}
