I think I've found the problem (just my guess),
public MySingleField(ClassOutlineImpl context, CPropertyInfo prop) {
this(context,prop,false);
}
/**
*
* @param forcePrimitiveAccess
* forces the setter/getter to expose the primitive type.
* it's a pointless customization, but it's nevertheless in the
spec.
*/
public MySingleField(ClassOutlineImpl context, CPropertyInfo prop,
boolean forcePrimitiveAccess ) {
super(context, prop);
assert !exposedType.isPrimitive() && !implType.isPrimitive();
System.out.println("Prop: " + prop.getName() + " " +
prop.displayName());
createField();
.....
}
From the constructor of SingleField, there is a statement call super()
which in turn call the constructor of AbstractFieldWithVar (superclass
of SingleField).
The problem is when I extend the SingleField class into MySingleField
class, the superclass is now the SingleField. So it calls the
2-parameter constructor of super class (SingleField), and then later
called the costructor of the 3-parameter constructor of SingleField.
So it calls the "createField" method twice (once from the SingleField,
second from the MySingleField)
I tried to extend also the AbstractFieldWithVar, but met the same
problem, so I extend also the AbstractField, but this time, failed,
while AbstractField is not accessible from outside class.
Is there any solution for this?
Can somebody give some examples about extending this
FieldRendererFactory???
Thanks.
