RE: [wsbpel] Issue - 77 - Under specified operation definitions

["Ugo Corda" <UCorda@SeeBeyond.com>]

Paco,

The question relevant to this discussion is the following: can the application using WSIF see (i.e. set or get the value of) the abstract message defined outside the abstract port? We know that BPEL currently cannot.
