Send message, `send(pid, message)`, from controller to a LiveView process not possible? If so, why not?

@coen.bakker

  def mount(_params, _session, socket) do
    case Process.whereis(:temp_name) do
      nil -> nil
      _ -> Process.unregister(:temp_name)
    end

    Process.register(self(), :temp_name)

    changeset = Accounts.change_user_registration(%User{})

One thing to watch out for - mount gets called by two processes during normal operation:

• in the Cowboy acceptor, with connected?(socket) false for the initial “dead view” render
• in the channel handler, with connected?(socket) true for subsequent updates

@coen.bakker

<%= hidden_input f, :sender_pid, value: inspect(self()) %>

Do you get a different result if you capture self in assigns instead of calling it directly here? I’m wondering if the change from being called from a different process isn’t getting picked up by the diff algorithm…
