在EORow或者VORow中对数据进行重复性校验

需求：在设置付款条件时不允许账期+付款方式重复。

方式1，在EORow的进行数据校验。

    public void setPaymentTermsId(Number value) {
        if(value!=null && !"".equals(value) && this.getPaymentMethod()!=null && !"".equals(getPaymentMethod()) ){
            validateRepeat(value, getPaymentMethod(), "TERMS");
        }
        setAttributeInternal(PAYMENTTERMSID, value);
    }

    public void setPaymentMethod(String value) {
        if(value!=null && !"".equals(value) && this.getPaymentTermsId()!=null && !"".equals(getPaymentTermsId()) ){
            validateRepeat(getPaymentTermsId(), value, "METHOD");
        }
        setAttributeInternal(PAYMENTMETHOD, value);
    }

    public void validateRepeat(Number payTerms,String payMethod,String cloumn){

            String validationStr = cachePay.getPaymentTermsId()+"-"+cachePay.getPaymentMethod();
            if(currentStr.equals(validationStr)){
                if("TERMS".equals(cloumn)){
