Subject: [owfe-dev] Subprocess call engine error
To: OpenWFE dev <[EMAIL PROTECTED]>
Cc: [EMAIL PROTECTED], [EMAIL PROTECTED]
Hello,
We are using route-web (densha), the version from May 30th, but we are
having a problem with a rather 'trivial' piece of code. It is just a
"subprocess call", as you can see below:
----------------
<process-definition revision="1.0" name="Proc-Main">
<description>
Main
</description>
<sequence>
<participant ref="alpha"/>
<subprocess ref="subproc"/>
<participant ref="alpha"/>
</sequence>
<process-definition name="subproc">
<sequence>
<participant ref="bravo"/>
</sequence>
</process-definition>
</process-definition>
-----------------
After "stopping" in participant "alpha", the subprocess "subproc" is
called, and the workitem can be seen in "bravo" store. But clicking in
"view" or "edit" results in the following error (listed at the end of
the email). We have tried in several machines, and using different
"participants", but we are unable to make it work. What is happening?
As a hint, I can say that this same piece of code runs perfectly in
OpenWFE 1.7.2 (in Java)
Thanks for your help, and kind regards,
Emilio
