problems with starting a task in uwl

Hi,

in our Portal 7.0 we have integrated employee and manager self services (Java ESS 600 SP 8 and Java MSS 600 SP 8/1). In detail we have a problem to execute a leave request task in the universal worklist (uwl).

If a manager clicks on the leaveRequestApprover task a popup opens with the following error:

Method ïPOST is not defined in RFC 2068 and is not supported by the Servlet API

(normally the iView leaveRequestApprover should be starting). This iView can be executed directly from the menu. The problem occurs only withing uwl .

I've read a lot of stuff here in the forum to solve the problem but it seems to be unknown. For example, I fixed the uwl config for leaveRequestApprover:

But the error still occurs...
