Re: Synchronisation problem on shape update ? [whiteboard] - Adobe LiveCycle 19-08-2009
A last question about Whiteboard:To handle Shape creation the WBmodel uses:NodeConfiguration.STORAGE_SCHEME_MANUALLetting the clients set the shape ID.Race condition which is actually handled well by the whiteboard is when user A creates a Shape with id #4 and B also creates a shape with the same id at the same time. Since they are using an internal increment counter to handle shape id this case may happen (at least it does in our whiteboard).My questions are:Why not use NodeConfiguration.STORAG...

Re: Synchronisation problem on shape update ? [whiteboard] - Adobe LiveCycle 19-08-2009
Wow that was a nice explanation !Ok i understant the root of our problems now, we only use one shape definition for creation and for properties which includes colors and position.Since we do not listen for our own published message we get out of sync on creation abd on updates. But now i have a theorical fix for both of them. A better approach for 1) would be to buffer my "latest submitted item". Essentially, if I've hit the arrow key 10 times really fast, keep track of the last message I send t...

Re: Synchronisation problem on shape update ? [whiteboard] - Adobe LiveCycle 18-08-2009
My plan was wrong.If after 300ms A publishes 'aaa' but then A types more and later receives the message that he sent to AFCS there are two choices.If he does not discard it, it will erase what he just added like "aaabb" and replace it with "aaa". Or maybe thats is where i should do a merge When it comes from myself if it hasnt been updated by someone else in the meantime ? (getting complicated).If he discards it then if a B user upates the same Text at a very close moment they may see different ...

Re: Synchronisation problem on shape update ? [whiteboard] - Adobe LiveCycle 18-08-2009
So if i understand well when it is from keyboard lets user the following scenariaUser A and B manipulates Text Shape T with content "zzz"User A adds 'a' and user B adds 'b' at the same time (i.e before B receives sync from A and A the sync from B)Then A is going to see zzzb and B zzza.However if B or A also update the UI from their own update message sent by AFCS (publisherid) it should be fine no ?If there are a lot of key events, we use a timer and buffer for Text to publish every 300ms so we ...

Re: Synchronisation problem on shape update ? [whiteboard] - Adobe LiveCycle 18-08-2009
Hi Hironmay,We publish the shape after our UI update, then wait for the publish back from AFCS, and then reupdate the UI on our side.What do you mean by " syncing from the model" a message received from AFCS ?Thanks

Measuring per user time usage - Adobe LiveCycle 16-07-2009
Hello AFCS Team,I would like to discuss the best strategies to measure the time of an AFCS session going between two users Tom the teacher and Sam the student. It is important since the pay per use model of AFCS will of course impact our way of making the client pay.- When Tom says the session is starting by toggling a button, the timer should start being taken into account only if two users are present in the room. Sam also see the timer but can not interact with it.- When Tom toggles off the b...
