spring - Spring MVC で要求属性エラーとして使用できる Bean 名 'bankDetails[0]' の BindingResult もプレーン ターゲット オブジェクトも使用できない

Question

エラーの原因となる私の JSP コード スニペットを次に示します。

<form:select path="bankDetails[0].applicantType">
    <form:option value="Applicant">Applicant</form:option>
    <form:option value="Co-Applicant 1">Co-Applicant 1</form:option>
    <form:option value="Co-Applicant 2">Co-Applicant 2</form:option>
    <form:option value="Co-Applicant 3">Co-Applicant 3</form:option>
    <form:option value="Guarantor 1">Guarantor 1</form:option>
    <form:option value="Guarantor 2">Guarantor 2</form:option>
    <form:option value="Guarantor 3">Guarantor 3</form:option>
 </form:select>

これが私のコントローラーコードです

   @RequestMapping(value = "enterBankDetails.htm", method = RequestMethod.GET)
   public ModelAndView enterBankDetails() {
      functionName = "enterBankDetails";
      logger.info("In "+className+" - "+functionName+" ");
      BankDetails details = new BankDetails();
      ArrayList<EntityBankDetail> entitityBankDetails = new ArrayList<EntityBankDetail>();
      for(int i = 0 ; i < 4 ;i++){
            EntityBankDetail entityBankDetail = new EntityBankDetail();
            entitityBankDetails.add(entityBankDetail);
      }
      details.setBankDetails(entitityBankDetails);
      return new ModelAndView("bankDetails/bankDetails", "command",details);
   }

ここにビーンコードがあります

public class BankDetails {
    private ArrayList<EntityBankDetail> bankDetails;
    private String[] entities;
    private int noOfBankDetails;
     private String test;
      //getter and setter methods
}

public class EntityBankDetail {
    private String nameOfBank;
    private String EMIforProposedLoan;
    private String nameOfBranch;
    private String city;
    private String accountType;
    private String accountNumber;
    private String applicantType;
           //getter and setter methods  
}

次のエラーが表示されます

java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'bankDetails[0]' available as request attribute
    at org.springframework.web.servlet.support.BindStatus.<init>(BindStatus.java:141)

助けてください。私は何が間違っているのか分かりませんか？

編集：テストにバインドすると同じことが起こります

<form:select path="test">
    <form:option value="Applicant">Applicant</form:option>
    <form:option value="Co-Applicant 1">Co-Applicant 1</form:option>
    <form:option value="Co-Applicant 2">Co-Applicant 2</form:option>
    <form:option value="Co-Applicant 3">Co-Applicant 3</form:option>
    <form:option value="Guarantor 1">Guarantor 1</form:option>
    <form:option value="Guarantor 2">Guarantor 2</form:option>
    <form:option value="Guarantor 3">Guarantor 3</form:option>
    </form:select> 

Neither BindingResult nor plain target object for bean name 'test' available as request attribute
