CMF Property Coloring

Hello,

I'm working through the CMF guide, and attempting to implement the task in 4.1.9 (Set the text color for a given zone) for a real world use case.

In my Innovator instance, I have a CMF Item Type called MyPQD, with two properties -- MyStringProp, and MyTextProp. (per an earlier example in the guide)

I'm using the following code, but not having any luck getting the color to change.  Any idea what I'm doing wrong here:

 var color = "#008000";
 var innovator = aras.newIOMInnovator();
 var myElement = innovator.newItem("MyPQD", "cmf_updateElement");
 myElement.setProperty("Text", MyTextProp);
 
 // create cmf style object and set available styles
 var cmfStyle = innovator.newItem("cmf_Style");
 cmfStyle.setProperty("text_color", color);
 myElement.setPropertyAttribute("MyStringProp", "style", cmfStyle.toString());
 
 // you should set value of property directly, otherwise it will be updated to empty value
 // for this purpose we need to get existing element with property
 var existmyElement = innovator.newItem("MyPQD", "cmf_getElement");
 existmyElement = existmyElement.apply();
 myElement.setProperty("MyStringProp", existmyElement.getProperty("MyStringProp"));
 myElement.apply();
