SetThemingColor of hidden elements

Question

How do i set the theming of components of a model which is hidden: If i not using the hideModel function everthing is working perfect, but if the model is hided i get an error 2 => BAD_DATA = 2,

this.viewerComponent.viewer.hideModel(this.viewerComponent.viewer.model);

The following things i already tried out:

this.viewerComponent.viewer.getHiddenModels()[0].setThemingColor(idArray[0], color, true);


this.viewerComponent.viewer.setThemingColor(idArray[0], color, this.viewerComponent.viewer.getHiddenModels()[0]);

This is not working for sure, since the model of the viewer will be null after hiding

this.viewerComponent.viewer.setThemingColor(idArray[0], color, this.viewerComponent.viewer.model());

Viewer Version 7

Thanks for help

Unfortunately, viewer.hideModel is a bit of a misnomer because it doesn't just hide the model, it actually unloads it. If you want to hide the model while still keeping all its data in memory, you might be able to achieve a similar result by calling viewer.hide(viewer.model.getRootId()). This will hide (or "ghost", if you have "ghosting" enabled; see below) the individual elements of the model while still keeping them in memory, so you can still configure properties like the theming color.
