Najeeb has a proposal out.

Najeeb:

I've made changes based on our last conversation.

greetings

discussion around getting rid of 2004.2 in proposal

I have to say that is for discussions like this that desktop sharing technology would help a LOT

[SPEL3011.1] A variable with the sca-bpel:multiReference extension MUST be referenced by one and only one partnerLink element with an sca-bpel:multiRefFrom attribute

furthermore ".. by *the* one and only one pL .. which *it* references" ... ?

Mike E:

As Mike R pointed out, 2 pL's couldn't share the same variable. Does this bother us?

Mike E:

Do we need the ability to have (nested) pL's that don't get exposed

Martin:

I think we need that

Mike: Better to assume exposure and have to explicitly suppress

Martin:

agree

Anish:

separate issue

Mike E:

Say I have inner partnerLink declared, and mark it with 'skip' -- I'm still able to copy an EPR into it programmatically.

Action: Mike E to file an issue about skipping a PL wrt CT introspection

Anish:

What's the value of plT and partnerRole in the multiRef vbl?

Najeeb:

it makes an association

Anish:

the runtime is going to the "exactly one pL referencing it" check already.

Anish:

So now you've got duplicate information that needs to be kept in sync by the editor

Danny, Mike E: +1

Mike E:

a pL that point to a variable in effect says "go initialize this variable for me"

Najeeb:

OK with removing the attributes

Anish:

If we do that, that would take care of another of my comments

Anish:

One more comment left - proposal talks about throwing an exception rather than generating an error. Rest of spec talks about generating errors.

Anish:

(Separate Issue - we don't really say what generating an error means...)

Action: Anish to file a separate issue about what a conformant runtime does when a non-conformant SCA BPEL doc is provided

Danny:

can remove 3005.1 since this case would have been rejected by static analysis

Anish:

reworded 3011.1 takes care of the need for 3005.1. Remove 3005.1

Mike E:

If we are able to characterize property-setting and multiref from as vbl initialization, we should do so, and disallow other initializers on those vbls. I'll raise such an issue.

Najeeb:

I came up with a virtual initialization expression explaining how the variable gets initialized

Mike E:

Don't like example. Problem is in implying $SCARuntime.xxx exists

Najeeb:

OK with removing example.

What about just <from> value that comes from reference </from> ?

Actually, more like <from> value that comes from the reference </from> (italicize the whole line, not just the contents of the <from> tag)

<from> extended expression that contains the injected value </from>

Anish:

enough changes that would require a new version of the proposal. Najeeb to produce it.

actually you dont extend <from>

Anish:

Hopefully, we can accept the edited proposal quickly next week

you have an extension element that replaces <copy/>

and that extension element can contain pretty well anything

@Mike - exactly, so it replaces the from and the to, so there's no extension of from itself. So we're good on the proposed wording?

Najeeb:

picture in section 3.2 needs to be changed as well if we go with this proposal

Anish:

Dieter has the source if you don't. Or Mike Rowley.

Anish:

Or could resolve with action for editors to fix.

referee calls time. Straggler roll.
