> Please let me know when it's done. << - Jira is the way
for you to raise bugs and get notifications when they are fixed. I am not going to send
you a personal letter when something you did not report properly gets fixed :)
What distinguishes Multiple instance subprocess from a plain subprocess are the collection
expression and the variable name properties. If you do not set those designer will
re-parse your subprocess as an embedded subprocess (default). The "could not find
process image" is a warning by the visual validation, but you can store your process
w/o ever creating a process image. To generate the process image just click on the PNG
button in the designer footer.
So I don't see this particular issue as a bug, but Instead of just saying that you
don't know how to do something (open a Jira), a simple google search would take you to
https://issues.jboss.org/secure/Dashboard.jspa
https://issues.jboss.org/secure/Dashboard.jspa where you can create an account and start
being part of community by contributing bugs that you find :)
Thanks.

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.

And then I triggered the "validate process" causes "There are no validation
errors".
So I'm not able to store the process with the node "multiple Instances" and
given parameter values for "CollectionExpression" and "Variable
Name".
