Contact Person Standard address data disappears on enter(first time)BP_CONT

Question

Hi,
During the quick create contact person creation (via accounts), based on client requirements the screen setting has been changed. (UI Configuration).
BP_CONT/ContactQuickCreateEF
So we have data displayed from 2 context nodes.
1. BUILHEADER
2. BUILCNTSTDADDRESS
We have done the enhancement for this view so get the bespoke field called Dept.No, and to provide dropdown.
Now when we enter the data for the first time, and press enter, all the data entered in BUILCNTSTDADDRESS disappears.
However after first time, the data stays back on the screen (works normally).
But, if we dont press enter, and simply press the back button, the data gets properly saved.
Do anyone have any idea what is causing this to fail for the first time.
I bebugged for few hours to find that super class CL_BP_CONT_CONTACTQUICKCR_IMPL got a method called CHECK_DATA_WAS_CHANGED. This gets triggered which calls the onsumbitonenter twice.
I also tried bypassing the enhancement via user parameter and this works fine.
Any idea what is causing this?

So, Rakesh, here you go:
We've needed to enhance method IF_BOL_BO_PROPERTY_ACCESS~GET_PROPERTIES of CL_BSP_WD_MIXED_NODE class in such way:
method IF_BOL_BO_PROPERTY_ACCESS~GET_PROPERTIES .
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""$"$:(1):CL_BSP_WD_MIXED_NODE:IF_BOL_BO_PROPERTY_ACCESS:GET_PROPERTIES:END                                                                 A
