Hey Michael,
I know a couple of guys have replied, but I think there is a much
simpler answer to your problem.
drop the item property from your page and add getter/setters that
update the your items list based on the index in the loop:
@Property
private int _index;
public String getItem() {
if ( items.size() <= _index ) {
// what to do when the index is out of bounds?
}
return items.get(_index);
}
public void setItem(String s) {
if ( items.size() <= _index ) {
// what to do when the index is out of bounds?
}
items.set(_index, s);
}
and update the loop div in your template to bind the index property:
<div t:type="loop" t:source="items" t:value="item" t:index="index">
The way your page was written you were telling tapestry to update the
item property for each value in the list, which it dutifully did. But,
what you really wanted was it to put the items into your list.
Hope that helps,
Josh
