Hi

i'm using Phoebus and have a ScrollBar widget.

I'm using master 2021-07-29 17:51 Phoebus version running on my Ubuntu 20.04 pc. (jdk 16.02)

I however cannot set the scrollbar's value in my script.

Here a part of my python script :

from org.csstudio.display.builder.runtime.script import PVUtil
from org.csstudio.display.builder.runtime.script import ScriptUtil

print ("Dup Range")
scrollB = ScriptUtil.findWidgetByName(widget, "Scrollbar")

scrollB.setPropertyValue("$(pv_value)", 1.0)   #  I need to set my scrollBar to 1.0 after range change trigger..not working

and the following error I get:

2022-03-24 11:17:11 WARNING [org.csstudio.display.builder.runtime] Script execution failed
Display 'EmbeddedDisplay Embedded-Harp.bob', Widget 'Spinner_4' (choice), JythonScript Live/duplicate_range.py
