Hi,

I have a waveform record setup as array of char (to support long string) and I'm trying to write a string to it via BOY Action button. I setup a "Write PV" action in the widget but the string does not get written, so perhaps long strings are not supported in BOY actions (it works for Text Inputs).

I tried a Javascript code to convert the string to an array of char via the following code:

importPackage(Packages.org.csstudio.opibuilder.scriptUtil);

var strArray = DataUtil.createIntArray(10);

var pv = widget.getPV();

var strText = "this is a test";

for(var i=0; i<strText.length; i++) {
  strArray[i] = strText.charCodeAt(i);
}
pv.setValue(strArray);

but the script throws an exception in BOY's console "Wrapped java.lang.Exception: Cannot handle type [I".

Is there any way in BOY to write a string to a waveform record as an array of char (support long strings)? I'm using SNS CSS 3.0.2 (Basic) for MacOSX.

Thanks in advance,
  Juan.
