Hi Swati,

That's because the text/value being displayed on a widget is not directly linked to a PV. From a script, you need to get get the PV itself and then use pv.setValue()

For further question on CSS, I suggest you use the CSS google group (https://groups.google.com/forum/#!forum/css-boy) is probably more appropriate for CSS specific questions

Hope that helps
David

Hello All.
I am getting trouble to get value of attached PV from CSS widget. Here is my script:
importPackage(Packages.org.csstudio.opibuilder.scriptUtil);
var i = "Swati_Soni";
var value1 = display.getWidget("text1").getValue();
var value2 = display.getWidget("text2").getValue();
display.getWidget("t_display").setPropertyValue("text", i+"_"+value1+"_"+value2);
From this script I am able to concatenate the two value in textupdate "t_display" (widget shows the output), but the PV attached into it can not get updated with this concatenated value.
Is there any method so that the attached PV of "t-display"can be updated with "Swati_Soni_value1_value2".
text1 and text2 has=ai EPICS record ,whereas t_display has stringin record.
Thanks in advance,
Swati
