Hi,

When I debug with firebug on my rap app, I found out that one of the GET requests is hanging forever without any response:

http://my_url?jsessionid=B49C13EB60AAFBE26B11C0E4AB338C25?no cache=1278115057630&custom_service_handler=org.eclipse.r wt.internal.lifecycle.UICallBackServiceHandler

The parameters are:

custom_service_handler org.eclipse.rwt.internal.lifecycle.UICallBackServiceHandler
nocache 1278115057630

The header is:

Date Fri, 02 Jul 2010 23:57:49 GMT

Content-Encoding gzip
Content-Length 345

I checked my code and it doesn't seem have any implementation related to UICallBackServiceHandler. Did I mistakenly do anything wrong? Or it's rap's implementation?

Hi Owen,

as you can see in the namespace,
org.eclipse.rwt.internal.lifecycle.UICallBackServiceHandler
is an implementation by RAP, it is used to handle UICallbacks.

To reproduce your problem, we'd need some more information, preferably
some example code.

Regards, Ralf

Hi Ralf,

I can't show you the example code now. But you can turn on firebug on http://codefaces.org and you can see the issue that I mentioned. I can tell you there is no UICallBackServiceHandler registered in the code.

Let me know if you need more info.

Thanks,
Owen

Hi Owen,

I can confirm that Firebug sometimes shows one hanging UICallback
request with the workbench demo, just after startup. Even running a job
does not close this request. I filed bug 319224.

Thanks for pointing this out.

Regards, Ralf
