I am trying to use <logic:iterate> to iterate through a list of order items. I cannot get it to work. I have seen several emails about patches for handling nested and indexed properties... OrderForm consists of an ArrayList of items.
I have added indexed getters
ArrayList getItems() and OrderItem getItems(int index) I can't see how an indexed setter would help for setting the
properties of OrderItems.
Here are parts of my orderform.jsp ============================================================== <form:form action="orderform.do" name="orderform"
type="OrderForm" >
<TABLE> <TR> <TD> Order Number : </TD> <TD> <form:text name="orderform" property="orderNumber" /> </TD> </TR> ... <% int count=0; %> <logic:iterate id="orderlist" name="orderform" property="items" length="2"> <tr> <TD> <form:text name="orderlist" property="itemNumber" value="<%= ((OrderItem)orderlist).getItemNumber() %>" /> </td> </TR> <% count++; %> </logic:iterate> <form:submit/>
</form:form> ============================================================== Unfortunately this generates input tags with identical names
for each iteration. This is a problem when you try to set the properties in the
items.
The value= part of the <form:text> tag is a hack to get the values from the Bean. Since the name generated needs to be unique I replaced the form:text lines with input tags like this: <input TYPE="TEXT" name="<%=
"items.itemName[" + count++ + "]" %>" value="<%=
((OrderItem)orderlist).getItemName() %>" />
the run-time expression used above cannot be used in the
form:text property value, so you have to use the input tag.
This still does not allow for setting the values in the
OrderItem...
Also what do you think of the name used above...
should it be items[0].itemName (more semantically correct - I think) or should it be
items.itemName[0]... I have tried both but that doesn't work...
Does anyone have any pointers/suggestions to get this to
work...?
Thanks in advance....
