When there is a direct view table with a write parameter, then values can be set through the element card.

I'm trying to execute a set parameter from an Automation script, but I get "invalid data" when trying from C# code and also from a set parameter action. I have tried by specifying the PID of the real write parameter and with the PID of the duplicate parameter. I have tried by specifying the display key and also the primary key, but all combinations give the same invalid data error. Is it possible that sets on direct view tables are not supported from Automation scripts and I should implement a workaround in the driver or should something else be called in the Automation script SetParameter call?
