Changing value of a transient attribute programmatically not working.

Question

Hi ,
I am using Jdeveloper 11.1.2.2.0
I have a ViewObject with following transient attribute
CheckBox       Boolean
ValidTillDate  Date
I want to perform following operation
1. If user selects CheckBox it will give ValidTillDate a future date.and if user uncheck CheckBox then ValidTillDate should become null.
2. If user changes ValidTillDate to current date then both CheckBox should become false and ValidTillDate should become null.
I have implemented it through ValueChangeListener my first requirement is working fine , in the second one though when the user gives current date to ValidTillDate then CheckBox gets unselected but the ValidTillDate is not getting null value.
I have used the following code:
public void ValidTillDateValueChangeListener(ValueChangeEvent valueChangeEvent){
  BindingContext bctx = BindingContext.getCurrent();
  DCBindingContainer binding = (DCBindingContainer)bctx.getCurrentBindingsEntry();
  DCIteratorBinding loationVO1Iterator = (DCIteratorBinding)binding.get("MyVO");
  if(Date.getCurrentDate().compareTo((DATE) valueChangeEvent.getNewValue())>=0){
  loationVO1Iterator.getCurrentRow().setAttribute("CheckBox", false);
  loationVO1Iterator.getCurrentRow().setAttribute("ValidTillDate", null);
}I think its because ValueChangeListener is called before the value is changed , so my programmatic changes are getting overwritten by the value userSelects.
What should I do?
Thanks,
Puneet

Questionably this sort of business logic could/should be implemented in ADF BC rather than the view layer.
