For some reason my observers are not being notified when i call the notifyObserver methods, using the java.util.Observable objects:
here is my observable object:
public class ProjectManager extends Observable
{
...
public void updateProjects(String project, String pack, String source, String ARN)
{
...
if(newSource)
{
tempPack.add(tempSource);
System.out.println("Notify observers: " + this.countObservers());
this.notifyObservers();
}
...
}
i can see from my output that the observer is being added but not being notified.
and my observer object looks like this:
public class IDE implements Observer
{
@Override
public void update(Observable o, Object arg) {
System.out.println("Notified");
}
For some strange reason the observable object is not being notified at all. Am i doing something wrong here?
You need to setChanged
before you notifyObservers
