I'm experiencing an odd behaviour which could possibly be a bug. I'm loading a CZML which defines some models to be loaded inside Cesium. I use a CzmlDataSource to display the data inside the Cesium Viewer.
If I remove the data source from the dataSourceCollection (without destroying it) and then add it back models don't get rendered anymore.
var dataSource = new Cesium.CzmlDataSource();
// here models are correctly rendered
// models are not rendered anymore.
It looks like models don't get loaded again in scene._primitives when adding the source back to the collection.
Is this a bug?
