Use of img.GET.java??

Question

When we create an Image component of our own, we create a script named img.GET.java inside the component along with the component script. We are setting the properties of the image that we selected from our design_dialog inside the component script and writing the rendering logic in img.GET.java. But, when I tried to debug the breakpoints in .java are getting bypassed without stopping. So how do we know that which one is getting executed first?? Does anyone know about the sequence of execution?? Please share with me..

Answer 1

Okay, understood.
However, I'm receiving a ClassCastException "unexpectedly".
Definitions:
public interface MyInterface { // definition }
public class MyAbstractSuperClass implements MyInterface { // definition }
public class MySubClass extends MyAbstractSuperClass { // definition }
public class ProvidingClass {
       * Returns instance of MyInterface.
      public MyInterface getMyInterfaceObj(Class className) {
            return myInterfaceObj;
}This code ...
Code A:
MySubClass mySubClassObj = (MySubClass)ProvidingClass.getMyInterfaceObj(MySubClass.class);... throws a ClassCastException.
Consider the following code based on the same definitions above.
Code B:
MyInterface myInterfaceObj = ProvidingClass.getMyInterfaceObj(MySubClass.class);
if (myInterfaceObj instanceof MySubClass) {
      // Do stuff
else {
      System.out.println("Found class:  " + myInterfaceObj.getClass().getCanonicalName());
Result:
... I get the following:
"Found class: fully.qualified.package.name.MySubClass"
Question:
Why do I receive a ClassCastException in Code A when the class that is returned in Code B indicates (through getCanonicalName() ) that it is of the type that I am trying to cast it to?
What would cause such an exception?
Thank you for your help!
