Hi,
You can clone the Category object implementanting the
java.lang.Cloneable interface (see the java api documentation) and
correct the code in the following way:
> 12. for (Iterator iterator = lALCategories.iterator();
iterator.hasNext(); )
> 13. {
> 14. lCCategory = ((Category) iterator.next()).clone();
> 15. lsName = lCCategory.getName()
> 16. /*
> 17. Some processing here on lsName.
> 18. */
> 19. lCCategory.setName(lsName);
> 20. lALOutPut.add(lCCategory);
> 21. }
