Re: #personal#Fw: Error in feching PV from CSS

[David Michel <dmichel76@googlemail.com>]

Hi Swati,

display.getWidget("t_display").getPV(); 

I didn't know one could do that! The other way is to "link" PVs to your script via the CSS interface (on the right hand side of the window when adding a script) which you can refer to by using an array called pvs[], so the first PV is pvs[0], second is pvs[1], etc.

But I got error "cannot convert Swati_soni_value1_value2 to java.lang.Integer 

Are you calling setValue() at all? If yes, then it looks like the function is expecting a Integer rather than a string.

It's hard to tell what's happening without the full script and the exact error message (incl. the line number where it occurs)

Thanks David,

display.getWidget("t_display").setPropertyValue("text", i+"_"+value1+"_"+value2);

display.getWidget("t_display").getPV();

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
