Hi, We just got the ESS payslip page where you can see the actual and previous payslips in a PDF format, but the issue is that when the user clicks on the Exit button the Portal hangs for a few minutes and end up with Web Dynpro Error.
My possible solutions are:
1. Either fix the issue with the Exit button or,
2. Hide the Exit button with the Personalization functionality, but for some reason I'm not being able to see this button in the Preview page through the PCD
Do someone knows how to fix the button or show the button in the Personalization page?
This is the log that I've got
com.sap.tc.webdynpro.services.session.LockException: Thread SAPEngine_Application_Thread[impl:3]_34 failed to acquire exclusive lock on client session ClientSession(id=(lwlpq01_LPQ_00)ID1265647750DB01522743276874704068End_742140988).

Hi,
We encountered the same error but with other scenario of UWL and that too with one particular user.
UWL application runs fine with other users, so went to kill the sessions of that particular user in VA.
To a matter of fact, some times it works and some times it doesnt...
Check out the possibilty,

I tried to kill sessions from the Visual Admin, but it doesn't really help, I have the same problem with all the users, I don't know how killing the sessions would work.
Any other suggestion?
Do someone knows how to Hide the Exit button through Personalization, it simply doesn't appear in the Preview Page as in the normal view.
Thanks
Not sure if it is the same issue, but earlier this year we had a similar problem with the exit button on a standard ESS Webdynpro screen causing dumps.
It wasn't the Payslip screen, but the dump you are seeing looks pretty much the same as what we were getting.
After applying Support Package Stack 12 for ERP2005 the problem went away.
Hi, this is more J2EE related stuff, SAP came with a solution but is taking ages to get the next page after the "Exit" button is pushed:
Go to VisualAdnmin >server(n) >Services >Configuration Adapter >
(Right side Pane) webdynpro >sap.com >tcwddispwda >PropertySheet
default.
Edit the property sheet and change the custom value for the property
"sap.locking.maxWaitInterval" to 200.
Note 1113811, explains why these kind of errors happen.
I still waiting for a better solution from SAP.
Cheers
