Figure 11-4. Category hierarchy before and after code execution
Adding the "Titanic" category to two categories looks the same as adding it to a single category. The
first category to which an item (category or other ACSObject) is added is explicitly added as the
default category. If a category/item only has one parent, that parent is implicitly the default.
11.2.2. Deleting a Category
// Fetch the Movies category from the database, assuming its id is 123
Category category = new Category(new BigDecimal(123));
// Delete the Movies category.
category.deleteCategoryAndRemap();
