             Summary: JMAP EventSource uncessary 'pushState' but no Event id
                 Key: JAMES-3554
                 URL: https://issues.apache.org/jira/browse/JAMES-3554
             Project: James Server
          Issue Type: Bug
          Components: JMAP
    Affects Versions: master
            Reporter: Daniel Gultsch
            Assignee: Antoine Duprat


The JSON object send as an event over EventSource contains a pushState paramater.
{code:json}
{"@type":"StateChange","changed":{"cf2e474f942d8ea3192028d2e37d5b08b3ddd36fb986d2ad6a19d66277a981c4":{"Email":"b7ee2d20-96ec-11eb-b57c-1b93c9e59cb7"}},"pushState":"ddc397e7a13fd27566ec3b7ed9bcc702c4c097e1ad83ebc8b909f3d5be459345"}
{code}
This pushState parameter is not defined in RFC 8620 7.1 and is therefor unnecessary. It is an extension that only the WebSocket protocol uses.

However EventSource defines it's own event ids inband that are probably (not knowing a lot about the server side of this implementation) functionally equivalent.

James should use the EventSource’s id instead of putting the id in the JSON payload.
