CoreViewPlugins receive remote messages and while replaying them locally, they can re-dispatch sub-commands. Currently, the plugin will re-dispatch using the 'global' Model.dispatch method which is the external entry point of Model and creates a new local history step when called.

This means that the coreViewPlugin can create new history steps when replaying a remote command, which ends up with their local changes sent to the network.

Two notes on that subject:

  • the local change will be sent before the revision is completely replayed, which means the revision ids of the messages are faulty and the message will be rejected by the server at first,
  • Having messages sent to the network upon reception of another message could lead to infinite loop of messages.

This revision adapts the dispatch of CoreViewPlugin such that they bypass the local history (and thus revision creation) when replaying remote revisions.

CoreViewPlugins receive remote messages and while replaying them locally,
they can re-dispatch sub-commands. Currently, the plugin will
re-dispatch using the 'global' `Model.dispatch` method which is the
external entry point of Model and creates a new local history step when
called.

This means that the coreViewPlugin can create new history steps when
replaying a remote command, which ends up with their local changes sent
to the network.

  replayed, which means the revision ids of the messages are faulty and
  the message will be rejected by the server at first,
- Having messages sent to the network upon reception of another message
  could lead to infinite loop of messages.
