Inventory Manager 4.0 - Issue in populating items collection for order

Hi

We are implementing agentry inventory manager 4.0 for our client. There is a scenario in which I am extending the Order object with my custom Java

class and trying to post in SAP along with Items .

After successfull post of the Order object along with items to SAP I need to get back the data to agentry client. For this we are using Object read steps.

I can see the order object getting repopulated. But the items collection within order object is not getting populated . Kindly suggest .
