ok, google would have been a solution for finding out how to create a issue, so far I
agree with :D .
But, then clicking on the png button in the designer as you told me, a "save as"
dialog appears and then I saved the process image on harddisk and then tried to store the
process again the following eror occures:
Unable to perform user action due to error(s).
Validate your process before saving, and view server logs to see error details.
