Question about text update widget is not updating text problem for phoebus

[neu lzf via Tech-talk <tech-talk at aps.anl.gov>]

Hi all,

I use binary SNS version of Phoebus and have two questions to consult you:

1)  ​I want to display "OK" text in Text Update Widget according to pv1 value if it is not equal to zero. I write embedded python script for phoebus as follows:

# Embedded python Script

from org.csstudio.opibuilder.scriptUtil import PVUtil

pv0=PVUtil.getDouble(pvs[0])

pv1=PVUtil.getDouble(pvs[1])

if (pv1!=0):

     widget.setPropertyValue("text","OK")

else:                 

  widget.setPropertyValue("text",str(format(pv0,".3f")))

the above script works well for CSS, while for phoebus it doesn't update text content to "OK" if pv1 is not equal to zero.  I have no idea what the problem of the script is.

2)  The script for phoebus doesn't show any error message if there is a syntax error in it, I wonder if I miss configuration to turn this function on and where to turn this function on.

Any help will be appreciated and thank you very much in advance.
