Bundle bundle = Platform.getBundle(element.getContributor().getName());
URL descriptorUrl = bundle.getResource(element.getAttribute("descriptor"));

From there on it's trivial.

Hello.

I have a custom extension point that defines the attribute "descriptor" which is of type "resource".
How do I now get an InputStream of that resource.
I can access the attribute itself with
String descriptor = element.getAttribute("descriptor");
What to do next to get an InputStream for this descriptor resource?

Best regards,
Kai

aggregateValidationStatus.addValueChangeListener(
  new IValueChangeListener() {
    public void handleValueChange(ValueChangeEvent event) {
      event.getObservableValue().getValue();
    }
  } );

So, Schroedinger's cat ... nice analogy ... I hope my AggregateValidationStatus doesn't contain any transitional states ;-)

And yes, it works now when calling getValue inside the change listener.
Is there an easy way to get the AggregateValidationStatus from within the change listener? A "(AggregateValidationStatus) event.getSource())" results in a ClassCastException (java.lang.ClassCastException:
org.eclipse.core.databinding.AggregateValidationStatus$1 cannot be
cast to org.eclipse.core.databinding.AggregateValidationStatus).
Do I really have to pass the AggregateValidationStatus to the change listener myself?

Thank you,
Kai

Are you doing anything with the value of the AggregateValidationStatus? in the change listener? AVS is backed by a ComputedValue which fires an event once and doesn't fire any more until you look at the new value. It's kind of like Schroedinger's cat--you don't get any more change events until you look in the safe. See ObservableTracker.getterCalled(IObservable). Then see IObservableValue and look for methods tagged @TrackedGetter.

We do this to avoid an event storm if several observables are changed rapidly. I think it will fix your problem just to call getValue() on the AVS inside the change listener.

Thank you,

I moved this post from eclipse.platform.pde to here.

Comments below.

My guess is that because you are using MAX_SEVERITY you might not be editing the field that has the current max severity, (i.e. you are editing a field with a lower severity validation status.

It doesn't work whatever text field I edit. handleChange is called once and after that not anymore.
And even when using MERGED I get the same behavior.
What do I have to do that handleChange method is called everytime the text field is modified?

That leads me to my next question? I want to listen to whenever a validate method of the above added validator's was called. I need it to setPageComplete of a WizardPage (as all text fields together have an influence on that).

Have you tried WizardPageSupport.create(DataBindingContext, WizardPage)?

Sounds ok, but it does also some things I don't like (updates the error message). Also there are several other cases I need the AggregateValidationStatus to work.
Any suggestions?

By the way I am using Eclipse 3.5M5.

Is that possible? Or any other suggestions?

Thanks,
