Your error indicates that pvs[0] is a different type of value than the function expects to find.
How are you creating the pvs list? And/or could you print what pvs[0]'s type is right before the command on line 24? From: [email protected] <[email protected]> on behalf of Gregory, Ray <[email protected]>

The PV is a mbbo record.

What is the value of pvs[0] ?
From:
[email protected] <[email protected]>
On Behalf Of Gregory, Ray
In a CSS BOY OPI I am calling PVUtil.getString() from a script attached to my OPI. I am passing it one of the script’s PV values:
Line … 22 from org.csstudio.opibuilder.scriptUtil import PVUtil, ScriptUtil 23 24 sensor_type = PVUtil.getString(pvs[0]) …
However I am getting the following error:
Traceback (most recent call last): File "scripts/lakeshore_input_setup_monitor.py.py", line 24, in <module> TypeError: getString(): 1st arg can't be coerced to org.csstudio.simplepv.IPV
What does this mean?
