As we've promised from the start, details of the script API are subject to change.Transitioning from BOY/Eclipse/SWT to Display Builder/Plain JRE/JavaFX, i.e. a completely new implementation, does require adjustments to scripts, and script of course won't work at all in the web runtime that uses HTML/CSS/_javascript_.

To port your BOY scripts, see https://github.com/ControlSystemStudio/phoebus/wiki/Display-Builder-Script-Compatibility regarding _javascript_ vs. jython, and for an example of updating macros for an embedded display see display builder examples, embedded displays, specifically https://github.com/ControlSystemStudio/phoebus/blob/master/app/display/model/src/main/resources/examples/embedded/update_display.py

Subject: [EXTERNAL] 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
