Show Failed Messages in Chat [ROUGH DRAFT] #1532
Description
This is the client issue for giving chat messages a failed state:
Currently, when a message is sent the UI shows it under the assumption it will be sent. If the recipient is hard to reach or offline, sending can take several minutes, during which time the message is not written to the database.
This can result in the user seeing their message, navigating away, and then their message disappears because it's not in the chat data returned from the server. The message then reappears later if the message completes its send.
The server is being updated to save the message before sending it, and to have a new failed parameter on each message. If a message is saved and the send fails, the send parameter will indicate that message failed.
Functional Requirements
-
If a loaded chat message has failed, show a failed indicator so the user knows it was not sent.
-
How will a live failure while the user is chatting be handled? We won't know whether a particular message is still sending or not. We could add a socket message for each send with a success or failure?
