Selecting a row in a grid using Process Orchestrator v7

Hi

We're trying to use Process Orchestrator to automate the creation of cases in our system for testing purposes. This is all working great apart from one thing I cannot seem to do.

I am trying to simulate the user selecting a row on a grid. We then want the code in the "When user selects row" to run. I can perform a Refill as if the grid had been selected, but I can't find any way to actually tell the refill action which row has been selected, and the code does not appear to ever run.

Anyone know how to do this?

(I'm using Process Orchestrator for .Net v7.6 SR3 if that makes any difference).
