Discrepancy in viewing the email screen in WebUI

Hi,

I have created an email activity( BT126H_MAIL) and added and attachment to email (GS_CM). When i Click on properties of attachment and view the properties screen and click on back, What ever data i have saved in email is not coming and its getting some default screen. Its due to related entity 'BTOrderHeader' is null, basically the values of 'BTOrderHeader' is not getting passed. Can any one advice on what is missing?
