Multi-value field in webflow

[jaredp]

I have a specific use case where a domain entity contains a few properties that contain multiple values. More specifically I need to have an enter form where an unlimited number of phone numbers can be attached to a person.

I imagine this use case it pretty common - as another example would be multiple attachments on a e-mail form.

Putting the phone number on a view by itself is possible but not what the client has requested.

public class Person{
  private String name;
  private List<String> phoneNumbers;

  //getter/setter for name

  public List<String> getPhoneNumbers(){
    return this.phoneNumbers;
  }
  public void addPhoneNumber(String phoneNumber){
    this.phoneNumbers.add(phoneNumber);
  }
}

<form:form commandName="person">
  <form:input path="name" />

  <input name="phoneNumber" type="text" value="" />
  <input type="button" value="Attach Phone Number" />
  <c:forEach items="${person.phoneNumbers}" var="phoneNumber">
    <c:out value="${phoneNumber}" />
  </c:forEach>
  <input type="submit" value="Next" />
</form:form>
