I'm writing an extension for the Forge Viewer and I ran into this problem when trying to use the setThemingColor() method in the "load" part of the extension:

function extensaoteste(viewer, options) 
 Autodesk.Viewing.Extension.call(this, viewer, options);
 

 extensaoteste.prototype = Object.create(Autodesk.Viewing.Extension.prototype);
 extensaoteste.prototype.constructor = extensaoteste;

extensaoteste.prototype.load = function() {
 this.onSelectionBinded = this.onSelectionEvent.bind(this);
 this.viewer.addEventListener(Autodesk.Viewing.SELECTION_CHANGED_EVENT, this.onSelectionBinded);

 this.viewer.setThemingColor(3554,new THREE.Vector4(255/255, 255/255, 102/255, 1));

The code goes on, but the rest works fine. As you can see, there is another part of the extension, with an event listener.

If I use the exact same line with the setThemingColor method in the extensaoteste.prototype.onSelectionEvent, it works perfectly. I understand it is the this.viewer part that isn't returning anything, however it works in the line above.

I have used the code from https://forge.autodesk.com/en/docs/viewer/v6/tutorials/events/#step-2-listen-and-react-to-an-event as a template.

I know this is probably a silly question, but I really can't understand it. Thanks for your help!

This is happening because the model geometry was not fully loaded when the call was made to set color and the null reference was not called out on this.viewer but on the model object:

Viewer3D.prototype.setThemingColor = function(dbId, color, model, recursive) 
 // use default RenderModel by default
 model = model ;

Try set color (and other fragment level operations) after the GEOMETRY_LOADED_EVENT is fired:

var viewer = this.viewer;
viewer.addEventListener(Autodesk.Viewing.GEOMETRY_LOADED_EVENT,()=>viewer.setThemingColor(3554,new THREE.Vector4(255/255, 255/255, 102/255, 1));
