Subject: Re: [wsbpel] Issue - 166 - Let's try it again






I don't think that the meaning of atomic is ambigous. It means that the
assign is executed has the properties of an ACID transaction. Requiring
that an assign is executed as the only activity in a process is far too
restrictive (and not necessary)...

Cheers,

Problem: The meaning of the term atomic in the BPEL specification's
definition of assign is ambiguous.

Proposed Change Of Language: The assign activity is atomic, that is, the
assign activity MUST be executed as if, for the duration of its
execution, it was the only activity in the process being executed. The
mechanisms used to implement the previous requirement are implementation
dependent.

             Thoughts?
