Binding objects in collection in command objects

[harry_m]

hi all,
i am new to spring mvc. i need some help on binding a DTO inside command to jsp. scenario is - i have an arraylist in command object that contains list of DTOs. they have some data like gender, title etc . i need to show these when form loads. user can change these values and i need to get them in my controller. so, binding shud be with DTOs inside arraylist.

i am able to display these values but when user changes, they are not getting reflected in controller.

here is code in jsp -

<c:forEach items="${command.arrListAdditionalPassengers}" varStatus="loopStatus" >
<spring:bind path="command.arrListAdditionalPassengers[${loopStatus.index}].ageGroup">
<input type=text value='<c:out value="${status.value}" />' />
</spring:bind>
<br>
</c:forEach>

Pls help.
Thanks in advance.

hi,
Problem solved. I was missing name binding to status.expression.
Read in a book that thru status.expression, spring binds control on html to corresponding elements in command object.
Here is the correct code thats working for me -

<c:forEach items="${command.arrListAdditionalPassengers}" varStatus="loopStatus" >
<spring:bind path="command.arrListAdditionalPassengers[${loopStatus.index}].ageGroup">
<input name='<c:out value="${status.expression}" />' type=text value='<c:out value="${status.value}" />' />
</spring:bind>
<br>
</c:forEach>

bye.
