I have a czml file with some locations inside to be shown in a map. This loads some 3D models in those locations. Those models change periodically, so the function lo load them is called every 5 minutes.
I can correctly load the data and show it, and it works correctly for a time, but after some calls to the corresponding function, the data is missing, even if the file still exists in the server. This file is read once and over (every time the function is called) and there is a moment in which it cannot be found, but it still exists. I don't care if the file is not found, what I want is to show the models with the last read information if this happens. This is the code inside that function:
var czmlSource = new Cesium.CzmlDataSource();
czmlSource.process('./data/myfile.czml?'+ new Date().getTime());
I have read that using "process" instead of "load" the previous data remains, in order to be loaded the next time, but I have checked that what it does is to add the new read information to the old one. This does not work for me neither, because the location of the models could change, and with "process" I could have double locations.
What I want is to load the file, and if it fails, keep the previous information.
Thank you in advance for any help,
