Hi,

Since the bpel file was stripped, I added it as a zip file.

Regards,

Danny

Just clarifying: variables are required to be assigned in the process.
Not
magically by the engine.

Your attachment has apparently been stripped (you can try to put it in a
zip) so it's hard to answer. They could have some sort of extension to
automatically initialize variables, which isn't part of the standard.
Although enabling it by default is slippery as it's non-standard. That
would
be a bit surprising though, their support for assignment seems very
partial
so it's odd they would have had implemented this before other standard
features. But I'm just guessing, seeing your process would probably
help.

Btw we have a patch proposition to add some sort of dynamic creation of
target path:

https://issues.apache.org/jira/browse/ODE-371

So we should get that pretty soon.

Thanks,
Matthieu
