Not sure if this is JEXL or Stapler....

Short question on an error I saw,

I had a class with a bunch of properties in it that was a publisher. The jelly files contained JEXL which correctly extracted these properties for display. I decided to split this class in two so that the base class was essentially the state, and the concrete subclass contained the logic that worked on the state - mostly because the class was big. Once I did this, JEXL expressions that accessed the state through the getters, started giving be reflection exceptions. I guess that methods only get resolved on the immediate class and not transitively up the hierarchy. 

Does anyone know if this is a limitation of JEXL, Jelly or Stapler? From the trace it looks like JEXL, but maybe there is an option that I don't know about?


abstract class Base extends Publisher {

  private String prop1;
  private String prop2;

  //...

  public String getX() {}
  public String getY() {}

  //...

  public void setX(String) {}
  public void setY(String) {}


}

class Concrete extends Base {
  // stuff actually dealing with being a Publisher
}
