Mass Leave Request approval in POWL

Hi @all,

we are using the POWL in a Launchpad and in a Portal. We use the Standard Workflow WS21500001 and the standard leave request applikation for approve the request.

The mass approval button functions don't work, if we open the request, close direcly the Pop-Up Window with the leave request application and click the mass approval button. Than the inplace window in the Portal keep white and the operation is aboard.

If i want approve some one time, i get the Error "...classname...".

Its works, when we direcly marked the request and press the mass approval button in the POWL.

We suppose a look problem?

Anyone have an idea?
