Adding View Criteria Row attribute in a particular order

Question

Hello friends,
We are using the Jdeveloper version 11.1.2.3.0.
We are populating the Query component filter programmatically , we want to show the filter order in a particular way.
The following is the code.
ViewCriteriaManager vm = view.getViewCriteriaManager();
oracle.jbo.ViewCriteria vca[] = vm.getAllViewCriterias();
oracle.jbo.ViewCriteria vc = vca[0];
vc.removeAllElements();
ViewCriteriaRow vcr = vc.createViewCriteriaRow();
vcr.setAttribute("A", "");
vcr.setAttribute("B", "");
vcr.setAttribute("C", "");
vcr.setAttribute("D", "");
vc.add(vcr);
vc.saveState();
view.applyViewCriteria(vc, true);
vm.criteriaChanged(vc);
But the filter is shown in the Query component in the following order.
C,A,B,D
Is there any way to add a filter in particular order?
Thanks in advance.
Best Regards,
Vijay

Sounds like your users are tough. You can provide your own ViewCriteriaAttributeHintsImpl and override the behaviour of HINT_NAME_FIELD_ORDER.
Create a custom ViewRowAttrHintsImpl class
public class CustomViewRowAttrHintsImpl extends ViewRowAttrHintsImpl {
@Override
public String getHint(LocaleContext locale, String sHintName) {
  if (HINT_NAME_FIELD_ORDER.equals(sHintName)) {
    //calculate and return field order here
  return super.getHint(locale, sHintName);
}Generate a ViewRowImpl and return your custom class in createViewRowAttrHints
@Override
protected ViewRowAttrHintsImpl createViewRowAttrHints(AttributeDefImpl attrDef) {
return new CustomViewRowAttrHintsImpl(attrDef, this);
}
