Problem with Date Picker and wwv_flow_item.date_popup()

Question

I have a Report based on the HTMLDB How-To “Build Tabular Forms for Multi-Row Operations”
This is my code:
select
X.RRIT_UID,
X.DOS,
X.CPT_CODE,
X.MOD,
X.DX_CODE,
X.CHARGES,
X.UNITS
from
(select
htmldb_item.text(1,RRIT_UID) RRIT_UID,
wwv_flow_item.date_popup(2,null,RRIT_DATE_OF_SERVICE) DOS,
htmldb_item.text(4,RRIT_SUBMIT_SERVICE_CODE,6) CPT_CODE,
htmldb_item.text(5,RRIT_SUBMIT_MODIFIER,3) MOD,
htmldb_item.text(6,RRIT_ATT_DIAG_CODE,6) DX_CODE,
htmldb_item.text(7,RRIT_BILLED_CHARGES,9) CHARGES,
htmldb_item.text(8,RRIT_UNITS,3) UNITS
from
RRIT_REPRICE_ITEM
where
RRRR_UID = :P5_RRRR_UID
union all
select
htmldb_item.text(1,null) RRIT_UID,
wwv_flow_item.date_popup(2,null,null) DOS,
htmldb_item.text(4,null,6) CPT_CODE,
htmldb_item.text(5,null,3) MOD,
htmldb_item.text(6,null,6) DX_CODE,
htmldb_item.text(7,null,9) CHARGES,
htmldb_item.text(8,null,3) UNITS
from
dual)

My problem is when I run the page and select a date from the Pop-Up calendar I get this error:
Line 10
Error: ‘opener.document.forms.0.f02.0’ is null or not an object
I know it is something to do with data formats and the fact that I do not fully understand the use of wwv_flow_item.date_popup().

Hi DK,
It is a WD Java application, Backend is ABAP (MM module).
The UI is input field, where the context attribute type is Date, So its been changed to Date Picker.
The problem is when the user runs the WD application in Portal, The calendar format is being changed for some users. That is for few users the Week starts with Monday and for few users the week starts with Sunday.
I need all the users to have Monday as the First day of the week.
Please let me know, what will be solution for this.
Since I haven't done anything in regard to date, it is a simple Date format.
Thanks & Regards,
Palani
