Subject: RE: [wsrp-wsia] [I#6]Update: Is groupId required?

Introducing an implicit transport level token that is not reflected in our application protocol (SOAP- headers or interface WSDL) seems bad on design principles alone, to me, as producers are not always going to be one (http or other transport) hop away from producers. Therefore the pattern should be:
initEnvironment(environmentID) - if environment needs to be explicitly established
operation(environmentID) - if operation is in the context of the named environment then the context should be explicit.
I don't mind limiting the use cases for initEnvironment (as long as it remains optional) but I do wonder why we are both trying to simply the semantics and adding an extra costly network round trip to the end user interaction (maybe initEnviornment and its result should carry a timestamp so that user dead time can be easily measured as well as a context/environment/grouping identifier? ;-)
How about instead limiting a new connection to only one outstanding getMarkup or performInteraction at first use so that a context can be established both at the transport and wsrp level? This avoids the extra initEnvironment round trip but I would still vote for some form of context/environment/group identifier to make explict the shared context.

Yup. Sorry. I'll update the list (remove the "we are postponing..." part). Note however that a "tentative proposal" email was also sent.

Hi Gil,
I think you got a little confused. Regarding this we said we will vote next week to remove groupId from the spec.
It was regarding the isRefresh that we said we will defer until after the JSR meeting.

Owner: Michael Freedman
Title: Is groupId required?
Since we now have initEnvironment, which is the solution for shared sessions, do we now need groupId, which was also defined as a mechanism for group sessions.
We are postponing this until we hear some more information from the JSR-168 liason people.
