java - Spring webapp フォームフィールドの値は常に null を返します

Question

この単純な問題を解決するために私が残したわずかな髪の毛を引き抜いています。コンパイルしてデプロイする Maven/Java7/Spring3/MySQL/Tomcat webapp を作成しました。私のクレジットカードブランドとクレジットカードフォーム/バリデーター/コントローラーは、それぞれのテーブルに行を挿入する際に問題なく動作します。しかし、私の連絡先フォームは表示されますが、bodyOfEmail に返される値は常に null です。それは非常に微妙なスペルミスまたは構成エラーであるに違いありませんが、私はそれを見つけることができません - 他の誰かがこれに光を当てることができますか?

ContactForm.java

public class ContactForm {

    private String bodyOfEmail;

    // accessors

}

ContactValidator.java

public class ContactValidator implements Validator

    private static final Logger logger = Logger.getLogger( ContactValidator.class);

    //constructors
    public ContactValidator() {}

    //stuff
    public boolean supports(Class candidate)
    {
        return ContactForm.class.isAssignableFrom(candidate);
    }

    public void validate(Object obj, Errors errors)
    {
        logger.debug("entering");

        ContactForm form = (ContactForm) obj;

        if( errors.hasErrors() ) { // could be a data binding error, could be all sorts of things
            logger.debug( "number of errors found:" + errors.getErrorCount());
            if( errors.hasGlobalErrors()) {
                logger.debug( "    number of global errors found:" + errors.getGlobalErrorCount());
                java.util.List<ObjectError> globalErrorList = errors.getGlobalErrors();

                }
            }
        } else { //no basic field errors detected, now apply business logic validation
            // validate textarea field
            String naughtyChars = "xxxx";
            if( form.getBodyOfEmail().matches(naughtyChars)) {
                errors.rejectValue("bodyOfEmail", "validation.negative", "bodyOfEmail contains naughty characters");
