Questions re ODE2.0-beta
Hi,
A have a few questions related to ODE2.0, would appreicate your comments:
1. The instance management implementation of fault() is empty at the moment.
Is there a plan to implement it?
2. I could not get correlation to work with 2.0. Is there a known problem
with it or is the problem local for me only?
3. Implicit initialisation for variables - this is one of the more annoying
side effects of using ODE comparing to other bpel engines. Is there a plan
to enhance this behaviour? (I know its part of the bpel spec, but it makes
the development of complex processes quite hard as you have to explicitly
initialise all variables before you can use them).
Thanks,
Dawg

No, it happened with "yes". I'm using the distribution by the way, didn't
build the latest version to check with it.

Hi,
Is point 2 below happening when you are using initiate with a value
"join"? I couldn't deploy a process which had correlation set with
initiate as "join", but it worked with initiate as "yes".
Thanks
Dhanush

Since it is part of the API it should be implemented. However AFAIK
nobody is currently working on that. If you'd want to create and submit
a patch, that would be highly appreciated ;)

A couple of weeks ago I've fixed an issue related to correlation. Please
see ODE-721, perhaps it's the root cause for your problems, too?

I tend to agree but the problem is that the initialization mechanism
will never be complete as it is impossible to guess if or how many
optional elements/attributes should be placed in the variable. Hence, I
really think this issue should be properly tackled by BPEL designers,
not by the engine itself. However, if someone is willing to provide
concept and implementation for such a feature, I'd be the last one who
would object to incorporate into ODE (as long as it does not break the
standard behavior).
Best,
Tammo

Thanks Tammo.
Re point 1, I definitely need it, but I hoped I'd be able to avoid diving
into the internal implementation... I will start looking into it soon, if I
something worth contributing, I sure will.

Since it is part of the API it should be implemented. However AFAIK
nobody is currently working on that. If you'd want to create and submit

A couple of weeks ago I've fixed an issue related to correlation. Please
see ODE-721, perhaps it's the root cause for your problems, too?

I tend to agree but the problem is that the initialization mechanism
will never be complete as it is impossible to guess if or how many
optional elements/attributes should be placed in the variable. Hence, I
really think this issue should be properly tackled by BPEL designers,
not by the engine itself. However, if someone is willing to provide
concept and implementation for such a feature, I'd be the last one who
would object to incorporate into ODE (as long as it does not break the
