How are conflicts handled in the global view or is alignment only if a role engages in message exchange? David: Basically yes. Alignment of variables can only occur as a result of a message exchange. e.g. the sending of an acknowledgement will often allow the sender of the original message to align his state with the state of the recipient. Even after alignment the variables/state of each participant is not the same. Monica: Make text more explicit then and acknowledge the risk of only depending on message exchange. 2135 1 martin.chapman 2004-08-12 16:04:23 +0000 Reclassified to requires clarification from monica 2145 2 martin.chapman 2004-08-19 15:11:28 +0000 Response: If you look at Section 2.42 (page 19), it indicates that only one role may have visibility via a locally defined variable to a maximum order amount, for example. The example states that this information is combined by one role with the actual order amount to direct the choreography. My question is if that information should be available to both/multiple parties (herein roles) participating in the choreography. If this distinction is made outside of CDL who is driving (I thought it was peer-to-peer)? Typically, to me, the parties would agree on the paths ahead of time and not indiscriminately let one role redirect that (unless specifically allowed in the technical agreement). A similar question was alluded to by Steve Ross-Talbot in his state alignment proposal ('Should only the recipient role in an interaction be able to use the contents of the message in a decision that would affect a subsequent interaction? Or should both roles that participated in the interaction have visibility to the same message?') 2516 3 gritzinger 2004-10-12 18:22:47 +0000 Proposal: http://lists.w3.org/Archives/Public/public-ws-chor/2004Oct/0021.html
