ADF BC - How to get validation picked up from the database.

Question

Is there a way the ADF BC can be created so it contains the check constraints from the database?
I assume if it did, it would pre-fill the "validation" branch in the Entity Object Editor.

Frank,
Thank you very much for your reply. I've set "valuePassThrough" property of the dropdownlist to true. In the valueChangeListener, my code looks like this.
public void TD_valueChangeListener(ValueChangeEvent valueChangeEvent) {
System.out.println("+++++++++");
System.out.println("TD_valueChangeListener");
Number n = null;
BindingContainer bc = this.getBindings();
if(bc != null){
System.out.println("bc is not null");
//get the selected TD
FacesCtrlListBinding TdIter = (FacesCtrlListBinding)bc.get("LandLegalView1Td");
if(TdIter != null){ 
System.out.println("TdIter is not null");
if(valueChangeEvent.getNewValue() != null)
try{n = new Number(valueChangeEvent.getNewValue());}
catch(Exception e){
e.getMessage();
System.out.println("selected TD index="+n);
//Object td = TdIter.getAttributeFromRow(n.intValue(), "Td");
Object td = TdIter.getAttribute(n.intValue());
System.out.println("real value of td=" + td);
}else{
System.out.println("TD is null");
}else{
System.out.println("TdIter is null");
My question here is: I tried two ways of getting the real value of the new selected value. One is "Object td = TdIter.getAttributeFromRow(n.intValue(), "Td");". The other is "Object td = TdIter.getAttribute(n.intValue());". None of them give me the new selected value but the old value. Did I do anything wrong?
