Spring:bind and nested objects

[aspringuser_7]

Hi

1.I am using a multi action controller which loads a form

i need to load the form which has nested object eg

class parent{
int id
string name;

Child x;
Child y;

}

Class child{
string addr1;

}


2. I tried using sping:bind to bind the input fields in jsp to the object when i submit the form it goes to a multi action controller.

Problem is

1. i am not able to retrieve the values from nested object child in m jsp
2.when i submit the form it throws exception invalid child -null

is there any thing i need to include in cotroller to get nested values ?


thanks

eg




<spring:bind path="company.address.street">
Name: <input
type="text"
value="<c:out value="${status.value}"/>"
name="<c:out value="${status.expression}"/>">
<c:if test="${status.error}">
Error codes:
<c:forEach items="${status.errorMessages}" var"error">
<c:out value="${error}"/>
</c:forEach>
</c:if>
</spring:bind>
when i submit
in controller i get null address

if address street has values it doenot get displayed in textbox

Please post also the SimpleFormController code... atleast "formBackingObject()" and "referenceData()" methods from it.

FYI
When you post code, use <CODE>your code here</CODE> tags (just replace the <> with brackets []. By this, the post is more readable.

hi

i am just calling

showMyView(req,res) - which just set my cmpany object in request and forwards to my jsp page

on submit i call

saveMyValues(http..req,res,Company command) function

both these functions are in multi action controller


i can get simple values like command.getCompanyName() etc

but if i bind company.address in my jsp ,on form submit i get null exception
