Proper detection when a session ends in RAP? [message #517007]

Hello RAP-Community!

I want to tidy up my application (remove observers and so forth) after a session ends.

From my perspektive a session ends if the user closes the browser window or a tab. A sessions also ends if a user reloads the rap page.

The problem is, that the a UI thread of a session is still running, even if the browser or tab have been closed. After a session end I want to tidy up the effected session parts of my RAP application.

There is the IExitConfirmation interface. But it's not working in every browser. It is also not possible to distiguish between tab close and tab change.

I also tried to register a listener to the display object to listen to Close and Dispose events. But nothing happens.

I'am running my applications SWT-like via the createUI-method:

while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}

		display.dispose();

		UICallBack.deactivate("callback" + this.toString());
		return 0;

Maybe somebody had the same problem and knows a work around?

Best regards
Eduard

Eduard,

did you read this?
http://wiki.eclipse.org/RAP/FAQ#How_do_I_get_notified_when_t he_browser_window.2Ftab_is_closed.3F
Also there are several posts on this newsgroup on the topic. The
newsgroup archive can be searched here:

Though a web search will also do.
