Value sent on outgoing port not received on first render

Not officially AFAIK. Could you give me a rework of your code with this new implementation?

If I understand what you’re saying I think its a similar problem to what I’ve come across already.
Take a read of this thread:

There’s currently no nice solution to this one either. I’ve kept the wait for element implementation in my solution. So that’s not too different from an arbitrary sleep.
