Destroy throws render error

Hello. I built an application using Resium which uses several models, tilesets, polyline and polygons.
All are components under the Viewer component. What is the right way to exit from the whole Cesium component?
When i try to destroy the models i get this error:

An error occurred while rendering. Rendering has stopped.
DeveloperError: This object was destroyed, i.e., destroy() was called.
