Hi,
I have a EmployeeDTO class with a getter, setter for AddressDTO class where AddressDTO class contains a list of addresses.
when i am trying to display the Employee address information i am getting an exception. please help!
My code goes like this:
class EmployeeDTO{
private AddressDTO addressDTO;
getAddressDTO() {...}
setAddressDTO(){....}
and other fields goes here...
}
class AddressDTO{
private List<String> addresses;
getAddresses() {...}
setAddresses(){....}
and other fields goes here...
}
struts action class:
class MyAction extends Action{
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest req,
HttpServletResponse resp) throws Exception {
// getting employee info from DB
req.setAttribute("employeeDTO", employeeDTO);
}
template code:
<table>
<tr><td>${employeeDTO.name}<td></tr>
<#list employeeDTO.addressDTO.addresses as address>
<tr><td>${address}<td></tr>
</#list>
</table>
Page is printing Employee Name but giving following exception:
Expression employeeDTO.addressDTO is undefined on line 15, column 19 in Employee.ftl.
The problematic instruction:
----------
==> ${employeeDTO.addressDTO.addresses} [on line 15, column 17 in Employee.ftl]
----------
Java backtrace for programmers:
