Restart application with no cid [message #1373461]

Hello!

We are facing a strange problem with our logout / restart mechanism. When we reload the page by executing a redirect via JavaScriptExecutor, the reloaded page sometimes does not start correctly and the browser only displays a few line of javascript. In Firebug I can see, that the redirected request still contains the old CID parameter. Can this lead to such problems? Does anybody know of a way to reload the page as if the user just requested it for the first time? Are there any other known problems or bugs when restarting a RAP Application? Unfortunately there are no errors in the client log or any other hints on what might be going wrong.

Edit:

This is what is printed in the browser when the page fails:

{"head":{},"operations":[]}

Any help would be great,

Thanks
Tibu

Hi,
no... I'm not aware about such problem. Could you open a bugzilla and
attach a simple project to reproduce the issue?
Best,
Ivan

Hello Tiburon,

we had the same problem problem with a RAP application a few weeks ago. We could solve it but I think our fix does not work in the general case. You should try to understand the following things:
When is your HTTP session destroyed?
When is your new (login again) HTTP session created?
Where are you redirecting to? (Into the same RAP app or to some external servlet / static HTML page?)
Please be aware of the RAP client trying to send a shutdown event to the server when the RAP client's JavaScript is unloaded! This can interfere with external (to RAP) servlets involved in the logout procedure.

It would help if you can explain your logout process in more detail.

Regards, Johannes.

PS: To prevent the RAP client sending the shutdown event, you can try this line before redirecting:

executor.execute("rwt.widgets.Display.getCurrent()._sendShutdown = function() {};")

Hello,

thank you very much for your support. We finally figured out, that our logout was executed twice. First manually and then again in preShutdown().

Greetings,
Tibu
