Hi Ben, a really basic example. I'm assuming your trying to loop the zones,
I hope this helps.
<t:Loop source="products" value="product">
${product}
<t:select t:id="cardType" validate="required" zone="${product}"/>
<t:zone t:id="cardTypeZone" id="${product}">
<t:if test="cardTypes">
<p> ${cardTypes}</p>
<t:if>
<t:zone>
<t:Loop>
@Property
private CardType cardType;
@Property
private String cardTypes;
@InjectComponent
private Zone cardTypeZone;
private String products = "desk,computer";
@Property
private String _product;
public String[] getProducts() {
return products.split(",");
}
public Object onValueChanged(CardType cardType) {
cardTypes = findCardType(cardType);
return cardTypeZone.getBody();
}
public String findCardType(final CardType cardType) {
switch (cardType) {
case DISCOVER:
return "Discover Card";
case VISA:
return "Visa";
case MASTERCARD:
return "Mastercard";
default:
return "American Express";
}
}
public enum CardType {
DISCOVER, VISA, MASTERCARD, AMEX;
}
