Bug: More than one input flow socket can be connected to the same output flow socket

[hybridherbst]

In this simple graph, only "world" is logged – my expectation is that "hello" and "world" are logged instead:

I could not find details in the spec on what happens when the same output flow socket is connected to multiple input flow sockets. I did find that there's a flow/sequence node but would not expect that to be necessary. My understanding is that the one value output can also be connected to multiple value inputs. cc @lexaknyazev, I might have missed a place where that is defined?

	"nodes": [
		{
			"type": "event/onStart",
			"values": [],
			"configuration": [],
			"flows": [
				{
					"id": "out",
					"node": 2,
					"socket": "in"
				},
				{
					"id": "out",
					"node": 1,
					"socket": "in"
				}
			],
			"metadata": {
				"positionX": "271.7791644049969",

This works:

So

• either the bug here is that all connected flows should be run,
• or the bug is that I can connect the outputs to more than one thing at all,
• and/or that there is no log telling me that I messed up.

[lexaknyazev]

An output flow cannot be connected to more than one input flow.

To have multiple output ops from the same node, use flow/sequence or chain the out output flows.

Thank you for the clarification!
Could you point me at the part of the spec where this is stated? I wasn't able to find it.

[lexaknyazev]

It's impossible by design given the JSON structure like

  {
    "type": "event/onStart",
    "flows": [
      {
        "id": "out",
        "node": 0,
        "socket": "in"
      }
    ]
  }

and this spec language:

The same id value MUST NOT be used more than once within each of the configuration, values, and flows arrays.

An explicit note won't hurt, of course.
