I used a ui-template node to create an SVG circle.
I used a JS script to set the circle's fill color.
I used an if statement to change the fill color with msg.payload, which comes in as a number specified using an injector node.
Everything works fine if I replace msg.payload with a number (to test the code). But nothing works if I try to use msg.payload to control the circle's color.
Is it not possible to access msg.payload in ui-template nodes? Is there magic sauce I need to apply for it to work?
