Hi,
I'm trying to learn BPM design in XI. I had started to configure a scenario from one of the blogs (/people/krishna.moorthyp/blog/2005/06/09/walkthrough-with-bpm).
I created a new Business Process in IR(as in step 8) but the screen under my newly created scenario was blank. I can not see any Graphical Definition, Process Overview etc. windows. So I clicked from menu Keyboard Shortcuts -> Show Editor/View Menu and this Java null pointer exception occured for both.
Does anybody have an idea? Why cannot I see those editor screens? Also, a senior XI developer had given a short tutorial a few weeks ago and developed a Business Process in IR on our server without any problems. I'm wondering what could have changed, with me as the only XI developer in my company..
Everything else seems fine, I can create data types, message types, interfaces, mappings, activated my change lists etc.. I also cleared my caches, re-installed JRE and deleted older Java files.
My XI is on a OS400 system, and I have already seen the note Note 859465 - NullPointerException in DTR/XI, but my exception details looks different.
Here's mine:
java.lang.NullPointerException
