Ognl variable name and get set problem

Note

This is the correct solution for OGNL over 2.7

In short: for a variable sLocale the correct set method is setSLocale(...) and not setsLocale(...)

public class LocaleAction extends BaseAction {

        private String sLocale;

        public String localeChange() throws Exception {
                MessageConfig.setCurrentLocale(sLocale);
                SessionUtil.getSession().setUser_locale( sLocale );

                if( redirect != null ) {
                        return REDIRECT;
                }
                return NOTHING;
        }

        // WRONG for OGNL > 2.7
        // this method will not be used by ognl to set the value
        // if the variable is public will be set directly, no set method will be called
        public void setsLocale(String sLocale) {
                this.sLocale = sLocale;
        }

        // CORRECT for OGNL > 2.7
        // this method will be used by ognl to set the value
        // the variable should be private, in this situation the method will be called.
        // if the variable is public the method might be not called ( not tested ).
        public void setSLocale(String sLocale) {
                this.sLocale = sLocale;
        }

}
