[CSS] change macro values with script

[Maurizio Montis <Maurizio.Montis@lnl.infn.it>]

Hello to Everyone,

i'm trying to develop a control panel in CSS and i want to change
dynamically the macro substitution in a linking container widget through
a dedicated script. Reading the help documentation, i saw the Macros
Property can be changed with this code:


Javascript:
	importPackage(Packages.org.csstudio.opibuilder.scriptUtil);
	var macroInput = DataUtil.createMacrosInput(true);
	macroInput.put("pv", PVUtil.getString(pvs[0]));
	widget.setPropertyValue("macros", macroInput);


In runtime, i expect the container widget has a new macro called "pv"
with value coming from my variable set as pvs[0] (in my case i'm using a
stringout record), but the only macro available is an element called
"LCID" that changes at every page refresh (for example LCID=LCID_872 of
LCID=LCID_880).

Is there any configuration i'm forgetting to provide the correct set of
macro to my widget?

Thanks in advance for any help!
