Hi:


What's the data type of the PV?

To debug, try adding

 

  print(str(pv.read()))


and then check in the terminal where you started CSS for the output.

Hi

My code :

1.     from org.csstudio.display.builder.runtime.script import PVUtil, ScriptUtil
2.     from org.csstudio.display.builder.model.properties import WidgetColor
3.     ss = ScriptUtil.findWidgetByName(widget, "ss_range")
4.     sx = ScriptUtil.findWidgetByName(widget, "rangeX")
5.     pv = ScriptUtil.getPrimaryPV(sx)
6.     pval = PVUtil.getDouble(pv)
7.     ss.setPropertyValue("text", str(pv) + " : " + str(pval))    ##

##  'pv' returns the right pv attached to my 'spinner'. This pv is passed via the script as '$(pv_name)'

##  pval returns 'nan' although my 'spinner' displays the value (1 to 6) depending my last selected value


Thanks

Amien
