Binding Data to <form:radiobuttons> in Spring MVC

[nepalibabu]

I have a <form:radiobuttons> component in my jsp page which binds to a collection.

example

public class Test {
   private Sex sex;
   private String[] sexes = {"male", "female"};

   public String[] getSexes() {
        return sexes;
   }

   public void setSexes(String[] sexes) {
        this.sexes = sexes;
   }

   public Sex getSex() {
        return sex;
   }

   public void setSex(Sex sexes) {
        this.sex = sex;
   }
}

I bind this data in jsp as below

<form:radiobuttons items="${test.sexes}" path="Sex.description"/>

My Sex object contain Male and M for description and code. Male is selected.

This works fine.

But when I try to use List<Sex> like this.

public class Test {
   private Sex sex;
   private List<Sex> sexes;

   public List<Sex> getSexes() {
        return sexes;
   }

   public void setSexes(List<Sex> sexes) {
        this.sexes = sexes;
   }

   public Sex getSex() {
        return sex;
   }

   public void setSex(Sex sexes) {
        this.sex = sex;
   }
}

<form:radiobuttons items="${test.sexes}" path="Sex.description" itemLabel="description"/>

Male is not selected. Same thing happens when I use <form:Select>

Can anyone tell what am I doing wrong?

Thanks.

You are binding to the description of Sex, which in this case is null... So there is nothing to bind... You should bind to sex and them create a SexPropertyEditor/Converter which takes the description (or id if it is from a database) and then converts that value to an actual Sex object.

Also your form data shouldn't be part of the form (it is simply reference data)...

Thanks a lot for the response.

I have never worked with Spring MVC before and needs to look into creating PripertyEditor. Thanks for the heads up.

Also your form data shouldn't be part of the form (it is simply reference data)...

I do not understand what you mean by the above note. if you can elaborate a little bit would be helpful.

Thanks again.
