User UI default values being lost

We have an ABAP webdynpro application that enables users to complete and submit a web form through the Enterprise Portal. The input fields have the standard UI element user default functionality via "User settings => Use current value as default"

What we are finding is that after the user has created and submitted the first form and then immediately returns to the function to create a new form the fields with the default values are now empty.

The defaults values are back again if the user logs off and on again or refreshes the Portal application.

Has anyone else experienced this issue and if you have is there a way that you know of so that the defaults are retained each time the user activates the create function or is required that the session be refreshed each time?

Not sure if it is setting we have missed or if the UI Element function is "functioning as designed"

We are on ECC6 Netweaver 7.0

Thanks experts

Regards

Gary
