You have added more actions to the Channels in V1.2. That's useful, but then comes the following questions/issues:
1) Are the channels started automatically upon creation ? I don't think so.
(I was wondering why I was not receiving emails ....)
In the Channel creation menu (and in the wizard) you need now to add a StartType similar to the connectors
2) In the admin GUI, it is inconsistent (and quite confusing) that the 2 actions "Update" and "Remove" have a visible action button, while the other actions (Update, Clone, Stop, Start, ClearQueue and Disable Input) are available as right-click menu as well.
Recommendation: make all actions available as action button and right-click.
What is the meaning of the DisableInput ?

1. Are the channels started
1. Are the channels started automatically upon creation ?
You are right. Adding a channel does not activate the channel. Note that the Status is "NotStarted" in the Status column. It has to be started manually by selecting "Start" from the context menu on that channel.
We will look into providing the start type as the channel is being created and making all actions available as buttons.
2. "Disable/Enable Input" specifies whether the messages are going to be placed or not in the queue regardless of the channel status. By default, input is enabled. For example, when the channel is defined but in NotStarted status yet, or Stopped, routed messages will be added to the channel queue unless the input is disabled for the channel. When input is disabled, the users will see their respective channel and the routes that use that channel as down.
Stopping a channel does not stop its queue, that is the routed messages will continue to accumulate in the channel queue. This allows the admin to stop and start the channel without losing any routed messages.
If the channel is to be stopped for a long time, select "Disable Input" to stop the channel queue as well.
Please refer to Channel tab Help for more information for the new context menu actions.
