Subject Re: [S2] ParametersInterceptor: Error setting expression
Date Tue, 05 Feb 2008 04:35:27 GMT

A param called "button.login" means the ParametersInterceptor has to 
call getButton().setLogin(val).

If you don't have a getButton() method, or getButton() returns null, an 
exception like this occurs while trying to set the parameter.
