I tried that and expressor crashed (again) as soon as I finished drawing a selection around it.
I didn't have time to put more details, but here is the windows error I am getting (in brief):
An error has occurred within studio:
Recursive call to Automation Peer API is not valid
Here's a screenshot of the error I got. I tried to get the Stack Trace as well, but it really crashed so I wasn't able to.
I'm on Windows 7 64-bit machine, in case it has something to do with my machine setup.
For now, I'm creating separate dataflows for each step. Btw, it'd be nice if I can copy-paste operators from one dataflow to another. Seems like you can't right now.
You are correct that there is currently no support for copy/paste. It would be nice to have. A similar approach can be achieved by converting the operator you want to copy into a template, then using the template on another step or dataflow.
I will forward your information regarding the crash to engineering. As a second option, you could try deleting the second step and then recreating. Not really a nice workaround, but OK for this first dataflow.
