I am trying to think through creating a page that allows the users to
dynamically add "phone" form fields for a "contact" (Contact model has
a collection on Phone objects). The method is similiar to this
example: http://www.quackfuzed.com/demos/jQuery/dynamicField/generalUse.cfm
Where I am having trouble is how to implement validation on the
collection of Phone objects and how to use addFieldError() in my
Validation function so that "cssErrorClass" works correctly. I have
googled around but have found bits and pieces with no clear answer.
How does Struts 2 handle validating elements in a collection?
I have written a bit of pseudo-code that might explain a bit more.
Has anyone done something like this? Am I missing a simple solution?
::Model::
public class Contact {
private Integer contactId;
private Collection<Phone> phones;
}
::Action::
public class ContactCreateAction extends ActionSupport implements Validateable {
public void validateCreate() {
// Validate Phone Entries Here
for (Phone phone : contact.getPhones()) {
if (phone.getNumber().length < 10) {
addFieldError(??HOW??);
}
}
}
}
::JSP::
<!-- Display Phone Numbers -->
<s:iterator var="phone" value="%{contact.phones}" status="rowstatus">
<s:textfield name="contact.phones" value="%{#phone.number}"
cssErrorClass="ErrorDataField" />
</s:iterator>
<!-- This section will also contain Javacript to add/remove phone
fields on the page -->
