Issue - 218 - Isolated scopes and partnerLinks, properties and correlation sets

Status: received
Date added: 20 Jun 2005
Categories: Data Handling
Date submitted: 13 June 2005
Submitter: Yaron Y. Goland
Description: The current text is not clear if isolation semantics apply to partnerLinks. The text just says 'variables' which is a bit ambiguous.

It would probably be productive to point out in section 13.6 (using non-normative language) that properties are just projections of variables and so any use of properties are also protected.

Finally, it seems to me that isolation semantics shouldn't apply to correlation sets. The only time it should matter is if the correlation set wasn't initialized before the isolated scope started and the isolated scope wants to guarantee to itself the right to initiate the correlation set. But that presents a pretty obvious race condition if you have two isolated scopes who both want to initialize the same correlation set. So my guess is that correlation sets aren't protected by isolation semantics.
Submitter’s proposal: Edit 13.6 to make it clear that partnerLinks are included in isolation semantics, point out the implications (using non-normative language) of properties and also point out that isolation semantics explicitly don't apply to correlation sets.
