Every example that has loadczml in it bombs out with an unexpected end of syntax for me. Anything to shed some light on this issue would be greatful.
What Operating System and Browser are you using?
Windows 7 IE8 with Chrome Framework installed.
Are you using CZML that shipped with Cesium, or your own? If the latter, open in a text editor and see if close brace / close bracket exists in the right order at the end. The writer may require you to explicitly close the stream.
I am using the CZML that shipped with Cesium.
