Programmatically adding two view criteria

Question

Hello,
I am using Jdev version 12.1.2.0.0 and i am trying to apply two view criteria to a view object:
ViewObject vo = ...
ViewCriteria vc1 = vo.createViewCriteria();
ViewCriteriaRow vcr1 = vc1.createViewCriteriaRow();
vcr1.setAttribute(smt,smt);
vc1.add(vcr1);
ViewCriteria vc2 = vo.createViewCriteria();
ViewCriteriaRow vcr2 = vc2.createViewCriteriaRow();
vcr2.setAttribute(smt,smt);
vc2.add(vcr2);
vo.applyViewCriteria(vc1);
vo.applyViewCriteria(vc2,true);
vo.executeQuery();
I don't know why, but it executes just the second view criteria.
Thank you in advanced.

From the dos it looks like you add multiple rows to one view criteria but can only apply one view criteria
public static void demoCriteria(ApplicationModule appMod)
  // Create and populate criteria rows to support query-by-example.
  ViewObject empView = appMod.createViewObject("Emp", "mypackage1.EmpView");
  ViewCriteria vc = empView.createViewCriteria();
  ViewCriteriaRow vcRow = vc.createViewCriteriaRow();
  // ViewCriteriaRow attribute name is case-sensitive.
  // ViewCriteriaRow attribute value requires operator and value.
  // Note also single-quotes around string value.
  ViewCriteriaItem jobItem = vcRow.ensureCriteriaItem("Job");
  jobItem.setOperator("=");
  jobItem.getValues().get(0).setValue("MANAGER");
  vc.add(vcRow);
  vcRow = vc.createViewCriteriaRow();
  ViewCriteriaItem salItem = vcRow.ensureCriteriaItem("Sal");
  salItem.setOperator(">");
  salItem.getValues().get(0).setValue(new Integer(2500));
  vc.add(vcRow);
  empView.applyViewCriteria(vc);
  // Multiple rows are OR-ed in WHERE clause.
  System.out.println("Demo View Criteria");
  // Should print employees that are MANAGER or have Sal > 2500
  QueryDemo.printViewObject(empView);
