Note that I haven't compiled or run any of this.
I would first expect my loop to look more like this:
<logic:iterate id='creditCard' property='creditCards' name='registrationForm'
length='3'>
<html:select name='creditCard' property='type' indexed='true'>
<!-- some options -->
</html:select>
<html:text name='creditCard' property='name' indexed='true'/>
<html:text name='creditCard' property='number' indexed='true'/>
<html:text name='creditCard' property='expMonth' indexed='true'/>
<html:text name='creditCard' property='expYear' indexed='true'/>
</logic:iterate>
I would have accessors for "name", "number", "expMonth" and "expYear" in the
CreditCard class.
At that point, I scratch my head, because I don't know how to represent indexed
properties in DynaActionForms. With a regular ActionForm, I would have the following
in my "registrationForm" bean:
public CreditCard getCreditCard(int index) { return (creditCards[index]); }
public void setCreditCard(int index, CreditCard creditCard) { creditCard[index]
= creditCard; }
public CreditCard[] getCreditCards() { return (creditCards); }
