Hey Guys,
-- we have a very heavy problem.
If a user clicks the edit button in the webpage, the user sets a lock to the databaserecord.
I know it is not the right way to handle it on the web but I have no choice.
I also read all the posts about not doing synchronus RPC calls in GWT.
But we need to clean up the lock if the user closes his window or tab.
We tried onClose() and onBeforeClose() but if we send a call to the server the thread is closed and the server doesn't get the request.
If we use an alert-message the server will cleanup the lock because the browser waits a few seconds.
Do you have any idea how to handle this problem?
Thanks in advance
Dominic
