Previously, when an `ngClass` expression evaluated to something that was not a string, array or object (and was truthy), an error would be thrown while trying to call `.split()` on a non-string value. This error was not very helpful for the user to identify the root cause of the problem. This commit fixes it by ensuring such values are converted to string. Fixes angular#16697

Or maybe it is better to just throw a more informative error instead. |
