      Description

      A DESCRIPTION OF THE PROBLEM :
      The issue shows up in a very simple test case containing an FXML file with a hierarchy of <ScrollPane><Group><Pagination> for which the pagination has an indeterminate number of pages. Although it is possible to select the final numbered page in the UI, a subsequent click on the ">" button causes an IllegalArgumentException to be thrown.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Build and run the test case.
      2. Click on the final page number in the UI.
      3. Click on the next button (">") in the UI.
      4. The console displays an exception.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The exception was not expected.
      ACTUAL -

      CUSTOMER SUBMITTED WORKAROUND :
      The exception can be avoided by replacing Group with the following class:

      >>> sample/SampleGroup.java

      package sample;

      import javafx.beans.DefaultProperty;
      import javafx.collections.ObservableList;
      import javafx.scene.Node;
      import javafx.scene.Parent;

      @DefaultProperty("children")
      public class SampleGroup extends Parent {
          @Override public ObservableList<Node> getChildren() {
              return super.getChildren();
          }
      }
