Wrapped list in command object

[Art Vandelay]

Hi all,

I have a list of input fields with a checkbox and label in front of every input field. The label titles are filled using a list of string values from the model. My command object contains a list of objects, with each object contining fields that map to checkbox, label and input. My problem is that i cannot manage to map these values to my command object. Below is the code that i have so far.

<form:form action="/myaction.htm" commandName="myCommand">
   <c:forEach items="${fieldNames}" item="fieldName">
      <form:checkbox path="field.checked" />
      <form:label path="field.name" title="${fieldName}" />
      <form:input path="field.value" />
   </c:forEach>
</form:form>

public class MyCommand {
   private List<Field> fields;

   public getFields() {
      return fields;
   }
   public setFields(List<Fields> fields) {
      this.fields = fields;
   }
}

public class Field {
   private boolean checked;
   private String name;
   private String value;

   public boolean getChecked() {
      return checked
   }
   public String getName() {
      return checked
   }
   public String getValue() {
      return checked
   }
}

FieldsNames is a list of String objects added by the controller to the model.
When running above code i receive the error message that class MyCommand does not contain a property 'checked' upon submitting form, which is ofcourse true, but then again, i do not see how to map the above tags to the properties of class Field instead of class MyCommand which is the actual command object. Any help is appreciated.

Btw. the controller code is ommited due to the fact that it is out of scope for the problem i am facing.

ANd it really isn't a Spring issue either, sort of.

I mean how are you going to loop through the fields in the MyCommand object to actually set the values in the form. Unless this form is for create only and not edit.

But also, this is a classic One to Many problem, which I myself am trying to figure out on the web layer side.

Thanks for your reply.

This is indeed a form that will be used to enter data, so i do have to loop through the list of objects in MyCommand object so set the entered values.

Could you please elaborate a bit more on what you mean with a classical one to many problem and what you mean with solving the issue on the web layer. Or give a small example of you would solve this issue. Thanks.


Btw. i posted this in the Spring section, due to the fact that i am using Spring MVC and the spring form taglib, therefore i thought that the problem might an incorrect use of the form taglib.
