How to update form item in IR with value when it is null when pressing Go?

Question

Hello,
in an IR i have created a Date Picker Item. This item i want when user enters page to have a default value. Also when the user clears this field i want the corresponding item to get a default value. i have achieved the 1st but not the 2nd. I need this replacement in the item value because it its needed in a between where date expression in the report query and i want to have the bind variables only, not NVL them in order to avoid scanning all partitions of table. Thi item is used as an extra search field in the Report and it is included in the Page Items to Submit | Advanced Report Attributes.
How can i do this ?
What i have set up atm:
Source Used
Always, replacing any existing value in session state
Source Type
PL/SQL Expression or Function PL/SQL
Source value or expression
TRUNC(SYSDATE)
and also in Default :
Default value
RETURN TO_DATE('01/01/1980','DD/MM/RRRR')
Default Value Type
PL/SQL Function Body
TIA

Dionyssis ,
Normally you could, but IRRs are a little different. You can use the page rendering options, but page submit options will not fire when the report is being redrawn.
To get you started, add this to the item's HTML Form Element Attributes:
onblur="this.value = $v('PX_HIDDEN_DATE_ITEM')"Then just create a hidden date item and give it a default value. This will keep you from having to get into JavaScript date formatting which is terrible when compared to Oracle.
