Problems to step into Process Diagram

Hi all,

I have created a sample worklfow with 2 subworkflows. When I try to click on the process diagramm I can not step into the subworkflows.

What can be the reason for this behaviour? I have installed the portal and configured the portal server instance. In webMethods Configuration ==> System Configuration I have configured the required settings for the workflow and integration server (IP and port).

Following fixes are installed:
PRTL_6-5-2_Core_Fix2
PRTL_6-5-2_Directory_Fix3
PRTL_6-5-2_Search_Fix2

Does anybody have some idea how I can fix the problem?

Regards,

Ferruh
