when I click on the button Info in the designer, it tells me that it's the above mentioned version 2.3.0.Final.
I would like to add, that if I give a name to the "CollectionExpression" and the "Variable Name", I cannot store the process due to the error "could not find process image". When I remove the node "multiple Instances" everything works fine again.
Alltough I don't know how to open a JIRA, I hope this still will be fixed. Please let me know when it's done.
