I am getting this error while using vf component attribute for passing custom setting name, however i am not getting any error if I am hard coding values instead of component attribute, and it is showing me other custom settings field value.  
How do I throw an exception? The developers guide helpfully tells me to use the throw statement and provide it with an exception object but then unhelpfully provides the following example:
 
throw <exceptionObject>;
 
I tried:
 
throw new Exception('error message');
 
but get the error - type cannot be constructed: Exception.
 
I did find something that said I could not construct any of the system exceptions so then what excepetion object can I provide to the throw statement?
