Bug 39244 modifiersChanged() hook not called in NewTypeWizardPage [code manipulation]
The modifiersChanged() hook in NewTypeWizardPage is not being called when a modifier radio-button is selected (public/default/private/protected), it is only being called if a check box is selected (abstract/final/static). I suspect a missing "else if" clause in typePageDialogFieldChanged() in NewTypeWizardPage is the culprit. As such am unable to extend NewTypeWizardPage and validate modifier settings (working on custom "class" wizard extension).
org.eclipse.jdt.ui/ui/org/eclipse/jdt/ui/wizards/NewTypeWizardPage.java
fSuperClassStatus= superClassChanged();
			fieldName= SUPER;
		} else if (field == fSuperInterfacesDialogField) {
			fSuperInterfacesStatus= superInterfacesChanged();
			fieldName= INTERFACES;
		} else if (field == fOtherMdfButtons) {
			fModifierStatus= modifiersChanged();
			fieldName= MODIFIERS;
		} else {
			fieldName= METHODS;
		}
		
		handleFieldChanged(fieldName);
	}		
	
			
	
	/*
	 * @see org.eclipse.jdt.ui.wizards.NewContainerWizardPage#handleFieldChanged(String)
	 */
	protected void handleFieldChanged(String fieldName) {
		super.handleFieldChanged(fieldName);
		if (fieldName == CONTAINER) {
			fPackageStatus= packageChanged();
			fEnclosingTypeStatus= enclosingTypeChanged();			
			fTypeNameStatus= typeNameChanged();
			fSuperClassStatus= superClassChanged();
			fSuperInterfacesStatus= superInterfacesChanged();
		}
