PrimeFaces ShowcaseUtil class in PF v12 still available?

Question

I can not to find class ShowcasesUtil, that is use to filters, sorting of PrimeFaces LazySorting, LazyFiltering. Example below:

public int compare(Customer customer1, Customer customer2) {
 try {
 Object value1 = ShowcaseUtil.getPropertyValueViaReflection(customer1, sortField);
 Object value2 = ShowcaseUtil.getPropertyValueViaReflection(customer2, sortField);
 int value = ((Comparable) value1).compareTo(value2);
 return SortOrder.ASCENDING.equals(sortOrder) ? value : -1 * value;
 }
 catch (Exception e) {
 throw new RuntimeException(e);
 }
 }

Found information that it is a part of PrimeFaces Extensions: primefaces.extension.showcase. I try with 11.0.6 but still can not find this class in package. How to use it?

I try find it in PrimeFaces Extensions showcase 11.0.6.

• WoAiNii: This one?
• Eiten: No, I check this before. There is no method: getPropertyValueViaReflection. That is the main issue that I have with this Class

Just look in the PrimeFaces GitHub repository. You can find the file in both the 11.0.0 tag and the 12.0.0 tag:

https://github.com/primefaces/primefaces/blob/12.0.0/primefaces-showcase/src/main/java/org/primefaces/showcase/util/ShowcaseUtil.java This is the method:

public static final Object getPropertyValueViaReflection(Object o, String field)
 throws ReflectiveOperationException, IllegalArgumentException, IntrospectionException {
 return new PropertyDescriptor(field, o.getClass()).getReadMethod().invoke(o);
}

You can simply copy it to your project.
