[jira] Created: (PIVOT-596) BXMLSerializer should call bind() on superclasses when appropriate

BXMLSerializer should call bind() on superclasses when appropriate
------------------------------------------------------------------

                 Key: PIVOT-596
                 URL: https://issues.apache.org/jira/browse/PIVOT-596
             Project: Pivot
          Issue Type: Improvement
          Components: core-beans
            Reporter: Todd Volkert
            Assignee: Todd Volkert
            Priority: Minor
             Fix For: 2.0


Scenario:

public class A {
}

public class B extends A implements Bindable {
    @BXML Foo foo;

    @Override
    public void initialize(...) {
        System.out.println(foo.getClass().getSimpleName());
    }
}

public class C extends B {
    @BXML Bar bar;

    @Override
    public void initialize(...) {
        super.initialize();
        System.out.println(bar.getClass().getSimpleName());
    }
}

Now, in test.bxml, you have:

<C/>

You expect the following output:

"Foo
Bar"

And yet we only bind the object to class C, meaning you instead will get a NullPointerException trying to de-reference 'foo'.

We should bind to all classes that implement Bindable.
