Missing connection in DAG for conditional execution

[FriederikeHanssen]

Hey!

I created a small example here: https://github.com/FriederikeHanssen/mre/tree/dag_conditional

Essentially, whenever there is a conditional execution the DAG is missing one connection it seems:

The DAG of this code snippet:

    if(params.echo){
        echo = TOUCH(params.echo).file
    } else {
        echo = DEFAULT().file
    }

    APPEND(echo)

renders to:

I would expect a connection between the process TOUCH and APPEND as well.

For what it's worth, you can do this:

echo = params.echo
    ? TOUCH(params.echo).file
    : DEFAULT().file

And I think it will render correctly. But it's probably only feasible for simple cases
