Not sure how the dyna forms work, but you will need to check it generates a
getItem(int num) method - this will be called when populating
item[0].quantity ie getItem(0).setQuantity(value).

I caught the DynaValidatorActionForm/DynaValidatorForm problem too after I
sent out the email and corrected it but it didn't help.
Here are a few lines of my JSP (which should explain the item/items
question):
<html:form method="post" action="saveEdit">
<c:forEach var="item" items="${Items.map.items}">
<html:text name="item" indexed="true" property="quantity" />
<html:text name="item" indexed="true" property="price" />
</c:forEach>
</html:form>
and here's the resulting html:
<form name="InventoryItems" method="post" action="/saveEdit">
<input type="text" name="item[0].quantity" value="10">
<input type="text" name="item[0].price" value="45.0">
<input type="text" name="item[1].quantity" value="">
<input type="text" name="item[1].price" value="225.0">
</form>
BTW: I tried updating my struts libs to 1.2.4 but that didn't help. I
also put a String into the Items formbean and a corresponding textfield on
the page and that data passes through just fine. It's only the item[x]
changes that fail.
Thanks,
Brady
