Accessing derived expression defined in OceanScript in Assembler

Greetings all,

This is a bit of a strange question, but I figured it would be the right forum. I have a Ocean script which runs a simple simulation with a swept variable using Assembler.

It runs fine and I can use the ocnxlOutputOceanScript() function to define a probing script which creates various outputs. I'm calling it with the option ?name "Ocean".

In my outputs setup, this creates the "Ocean" script and there are various derived outputs. For example: "Ocean:out_wave"

What I would like to do is to define a new ocnxlOutputExpr() calling the new ?evalType 'sweeps option to evaluate across the sweep.

e.g. ocnxlOutputExpr( "(value Ocean:out_wave 1n)" ?name "1ns_value" ?plot t ?evalType 'sweeps)

However, this always gives me an 'evalError' as it claims to not understand what the variable named "Ocean:out_wave" is. 

I saw that the ocnxlOutputOceanScript() does allow the option ?evalType corners, but this doesn't feel correct.

Any ideas?
