Subject:	Phoebus and dynamic macros

Hello,

I’m trying to migrate to Phoebus for our new development and I’d like to be able to set Macro dynamically (for my hundreds of acquisition channel for example). I was able to do that with CSS boy using script.

According to https://control-system-studio.readthedocs.io/en/latest/app/display/editor/doc/property_type.html?highlight=macros#macros-property it seems possible also.

But when I applied the example to an “Embedded Display”:

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

var macroInput = DataUtil.createMacrosInput(true);

macroInput.put("CHANNEL", PVUtil.getString(pvs[0]));

widget.setPropertyValue("macros", macroInput);

I got the following exception :

[..]

Caused by: java.lang.Exception: Need Macros, got {CHANNEL=2}
at org.csstudio.display.builder.model.properties.MacrosWidgetProperty.setValueFromObject(MacrosWidgetProperty.java:53)

[..]

CHANNEL=2 because my PV loc://macroValue is set to 2.

seems to come from here but it's not really understandable for me

https://github.com/ControlSystemStudio/phoebus/blob/1a42ce4afc128f32b845db985ed7966f94078032/app/display/model/src/main/java/org/csstudio/display/builder/model/properties/MacrosWidgetProperty.java

Is the example incorrect, or is it not usable on an "Embedded Display" I've tried on a simple windows, i got the same result

Thanks in advance
