How to apply a generic array comparison expression binding

Hi Everyone,

I worked out how to implement this.

I added a transform script on the 'props.scheduledEvents' of the Equipment Schedule component binding itself.

Process:

  1. Loop over each event.
  2. Copy it (dict(e)).
  3. If .label == "TEST", set ["color"] = "#6ECEB2"; otherwise, set a default.
  4. Append the copy to a new list.
  • Output: Return the new list. Each event now has its own "color".
  • Outcome: The component (e.g. the Schedule) automatically consumes that "color" field to render events with the correct hex code.

def transform(self, value, quality, timestamp):
	# Transform script for property binding. Assume "value" is the incoming array of event‐objects.
	events = value  # e.g. [{ "itemId":1, "eventId":16, "label":"TEST", ... }, {...}, ...]
	
	# We'll produce a new list, so that each event gets a "color" attribute based on its label.
	out = []
	
	for e in events:
	    # Make a shallow copy so we do not overwrite the original
	    newEvent = dict(e)  
	
	    if newEvent.get('label') == "TEST":
	        newEvent['backgroundColor'] = "#6ECEB2"
	    else:
	        # either leave it blank or give it a default color
	        newEvent['backgroundColor'] = "#FFBE9F"
	
	    out.append(newEvent)
	
	return out

Hope this help's anyone else.
