------------------------------------

             Summary: Need to make load/store work correctly for all containers
                 Key: PIVOT-945
                 URL: https://issues.apache.org/jira/browse/PIVOT-945
             Project: Pivot
          Issue Type: Bug
          Components: wtk
    Affects Versions: 2.0.4
         Environment: All
            Reporter: Roger Whitcomb
            Assignee: Roger Whitcomb
            Priority: Minor
             Fix For: 2.1


The Component.load and Component.store methods are used to implement data binding between
components and their backing data objects.  On Container, the load/store methods are coded
to propagate the load or store down to the children.  But, not all subclasses of Container
actually have children.  Viewport/ScrollPane (for instance) only have a "view" which is not
in the child component list.  TablePane and GridPane have rows and columns which are also
not in the child component list.  This limits the effectiveness of data binding, in that you
basically can only use it within a Form, or other simple layout container (such as BoxPane),
but not in the more complex ones.  So, the idea would be to implement special versions of
"load" and "store" on these other containers so that the operation propagates correctly down
the actual component trees.
