Dear All,

I have a View (eclipse 4 kepler) which contains many controls like Text, Spinner, Combo etc.

I am using the data binding framework to validate individual controls and add a tiny decoration to the fields requiring attention.

After the user has filed all fields they need to press on a button to submit the information to a queue.

I would like to implement a method to scan all of these fields and check if any of them are having IStatus.ERROR in them so that I can pop up a dialog informing the user that the respective field needs to be corrected.

How would I go about scanning these field and finding out what went wrong?

I tried the following but it does not pickup a field which has wrong data:

IObservableList vm = m_bindingContext.getValidationStatusProviders();

for (Object o: vm) {
  ValidationStatusProvider v = (ValidationStatusProvider) o;
  IObservable iob = (IObservable) v.getTargets().get(0);
  if (v.getValidationStatus().equals(IStatus.ERROR)) {
    System.out.printf("Field has an error.\n");
  } else {
    System.out.printf("Field  has is ok.\n");

Any advice is greatly appreciated.

Kind regards,
