Question about initialize variables and selectionFailure
Hi,
I've been reading up on the BPEL 2.0 standard and it states that all
variables should be initialized before they can be used (by way of
creating an assign activity to copy a 'literal' to the actual variable).
I've created the attached process and it fails to run in ODE 1.2 (on
tomcat 5.5). When I run the same process in the BPEL SE of OpenESB it
runs fine. So my questions are:
- Are my variables initialized properly?
- Why do I get a selectionFailure in ODE, and not in OpenESB
(both are BPEL 2.0 complaint)
This is (part of) the logging I'm getting in ODE:

Any thoughts on this would be great.

As expected, your BPEL is not portable. It does not initialize the variable
$OpvragenVoertuigBasisIn before selecting into it. I'm surprised it runs in
OpenESB but they may have relaxed their requirements, as we have with
ODE-371 (Auto Complete Copy Destination) which will be available in Ode 1.3.
For the time being, you can add the following assignment after the first
<receive> to make it work:
<assign name="Assign">
<copy>
<from>
<literal>
<ns0:Kenteken/>
<ns0:Meldcode/>
<ns0:Identificatie/>
</literal>
</from>
</copy>
</assign>
cheers,
alex

Hi all and Matthieu,
Did anyone have a change to look at what I'm doing wrong. I really want
to fix this issue.
Thanks and kind regards,
Danny

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
