Hi Dawg,

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).
