command object having List field

[anicraj]

Hi,
Am having a command object which has a List type field. For example, Customer can have multiple addresses and so am having it as a List
<code>
public class Customer{
private String customerName;
private List<Address> address;

--getters and setters--
}
</code>

My question is to how do i map the form fields with this command object. My form will have fields for entering 2 addresses. What should be given in the path attribute of the <form:input tag.

any help is appreciated.

Thanks

Example

<form:input path="address[0].addressLine1"/>
<form:input path="address[0].addressLine2"/>
<form:input path="address[0].zipCode"/>
<form:input path="address[1].addressLine1"/>
<form:input path="address[1].addressLine2"/>
<form:input path="address[1].zipCode"/>

Hi,
still its not working,getting the following error

Invalid property 'address[0]' of bean class
Cannot access indexed value of property referenced in indexed property path 'address[0]': returned null

So i tried initializing the list as
private List<Remark> remark = new ArrayList();

Invalid property 'remark[0]' of bean class
Index of out of bounds in property path 'address[0]'; nested exception is java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

any help is appreciated.

Thanks

If you know there's only going to be two Address items in the array you should add them after instantiation.

private List<Address> addresses = new ArrayList();
addresses.add(new Address());
addresses.add(new Address());

Thanks it worked, but another problem. If i add more combo boxes, it makes the page very slow, it takes ever to load the page if it has 3 combo boxes whose values are fetched from db and populated in the referenceData method. Following is the jsp am using to load the combo boxes

<tr><td>Status</td><td>:<form:select path="status"><form:option value="-1">SELECT...</form:option>
<c:forEach var="item" items="${cStatus}"><form:option value="${item}">${item}</form:option></c:forEach></form:select> </td></tr>

Likewise i have 4 more combo boxes

Can someone tell me why the page is taking ever to load it, sometimes timeout error?If i remove all the combo boxes, the page is fast with all other form fields

any help is appreciated

thanks

Hi, As stated above, I have a situation where the Command object has a List field.

On the form I have check boxes and the selected check box items should map to the List field of the command object.

Can anybody explain How to achieve this.


Code: -
----------- Command Object --------------


public class PlayerGroup {

private String name;
private List<Player> teamsAssociated;

...
....
.....
......
}


------------- JSP ---------------------
.
.
.
<c:forEach var="player" items="${playerList}">
<tr>

<td height="20" class="labelSmall"><form:checkbox path="teamsAssociated" value="${player}" label="${player.name}"></form:checkbox></td>
<td align="left"><c:out value="${player.name}"/></td>
</tr>
</c:forEach>




In the above code the form does not even being Submitted.

Please give your suggestions.
