Is anyone using AutoBean in a JRE environment successfully? When trying a
very simple test I get a NPE when I try to use
AutoBeanCodex.encode(myAutoBean)
My Bean interfaces look like this:
public static interface Point {
Long getX();
Long getY();
void setX(Long x);
void setY(Long y);
}
public static interface PointList {
String getName();
void setName(String name);
List<Point> getPoints();
void setPoints(List<Point> points);
}
I'll omit the implementations for brevity but they are just standard objects
with some getters/setters.
My bean factory:
public static interface MyFactory extends AutoBeanFactory {
AutoBean<Point> point();
AutoBean<Point> point(Point instance);
AutoBean<PointList> pointList();
AutoBean<PointList> pointList(PointList instance);
}
I can create the AutoBean<Point> , AutoBean<PointList> ok from my factory.
I can use AutoBeanCodex to encode a Point, and it emits the correct Json.
If I try an encode a PointList object however, AutoBeanCodex.encode() throws
a NPE. Its certainly the List<Point> which is causing it, as if I remove it,
it works ok. And If I make PointList contain a few direct references to
Point beans, that also works (so if PointList has 'Point getPointA()',
'Point getPointB()', it does encode everything correctly.)
Am I missing something obvious? The code to test is below.
public void listtest() {
Point o = new PointImpl();
Point n = new PointImpl();
PointList plist = new PointListImpl();
List<Point> points = new ArrayList<Point>();
o.setX(20L); o.setY(30L);
n.setY(60L); n.setX(80L);
points.add(o);
points.add(n);
plist.setName("OH");
plist.setPoints(points);
MyFactory fact = AutoBeanFactorySource.create(MyFactory.class);
AutoBean<PointList> alist = fact.pointList(plist);
System.out.println("Splittable Payload:" +
AutoBeanCodex.encode(alist).getPayload());
}
java.lang.NullPointerException
