UIMA-AS and a custom Flow Controller
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi list,
we are having a problem deploying our Aggregate Analysis Engine with
UIMA-AS.
The aggregate contains a custom flow controller together with a fixed
flow setting. For the flow controller a custom type has been introduced
that can be altered on any of the AEs in order to "stop" processing the CAS.
If we now delpoy this aggregate with "async=false", everything works
fine. We can send CASes to the aggregate and get the resulting CAS.
If we however deploy the aggregate with "async=true", the bypass
controller stops with the exception that the "BypassIndicator type has
been used in the Java Code but not declared in the XML".
The controller's descriptor does contain the type information! Can
anyone help out? Should we import the type somewhere else? Is this
possible at all with UIMA-AS? As far as I can see from the documentation
an AS aggregate can contain a flow controller, right?
Best,
Daniel

Yes, this is a bug. It will be addressed today.

Yes, the Flow Controller descriptor containes the types it needs, i.e. imports the type system descriptor...

I have also thought that it might be a bug but I have to admit that I don't know enough of the internals to determine if it is a bug or a feature? :)

This is due to the fact that the aggregate in its original shape is more complex and I only used this setup to test the AS stuff. This again is the origin of my problem, that the type defined by the flow controller is absent if I am deploying the aggregate asynchronously.

You found a workaround, but I wonder if there is still a bug in
UIMA-AS here. Did your Flow Controller descriptor import the types
that it needed, yet the Flow Controller still got an exception trying
to access them? That shouldn't be the case. It sounds like UIMA-AS
is failing to add Flow Controllers' type definitions to the aggregate
AE's CAS definition. Jerry, do you think that is possible?

Hi again,
after some days of testing and debugging I finally came up with the reason for my problem.
This is the setup I have:
1. A simple Analysis Engine importing a typedescriptor
2. A Flow controller importing another typedescriptor.
3. An Aggregate AE importing both.
You will notice, that there now is no AE using the flow controller's types. This is due to the fact that the aggregate in its original shape is more complex and I only used this setup to test the AS stuff. This again is the origin of my problem, that the type defined by the flow controller is absent if I am deploying the aggregate asynchronously. If I deploy the aggregate synchronously the CAS contains the flow controller's type.
So the solution simply was to import the type in the AE descriptor. One remark or open question at this point is if it is intentional that in the async=false case the flow controller's type is imported in the CAS and in the async=true case it is not?
Anyways, problem solved. Thanks for the feedback.
Daniel

Not sure but it might be a possibility. What we are observing is that if
we start the aggregate with "async=false", the bypass indicator type is
present in the cas. If we start with "async=true" it is not. All other
types however are the same.

So far we have no other delegates in the deployment descriptor, i.e.
there are no other AEs running remotely.

I will try to create a basic example, but I am not able to do so before
tomorrow...
Thanks for any hints... ;)

This may be related to a recent Jira issue:
https://issues.apache.org/jira/browse/UIMA-1580. A work-around may be
to create one type system descriptor for all the types in your system,
and import that type system into all the components. (However, this may
trigger the NPE mentioned in that other Jira).

Besides setting async=true, are any of the delegates becoming remotely
deployed services?

Yes, certainly.
It might help diagnose things if you could post a smallish example of
something which isn't working, with the exact descriptors being used.
