changing FocusTraversalOrder has no effect if a if TableLayoutBuilder creates cells without components
------------------------------------------------------------------------------------------------------

                 Key: RCP-613
                 URL: https://jira.springsource.org/browse/RCP-613
             Project: Spring Rich Client Project
          Issue Type: Bug
    Affects Versions: 1.1.0
         Environment: Windows XP, Java 1.6.0_16, Mac Os, Java 1.6.0_13
            Reporter: Thomas Fahrmeyer
            Assignee: Lieven Doclo
            Priority: Minor


Using a FocusTraversalOrder set on the TableLayoutBuilder does not behave correctly if the form contains cells with no components. These cells
can be created by just using layoutBuilder.cell() and used as, for instance, placeholders.

In the Method TableLayoutBuilder.setFocusTraversalOrder(int traversalOrder) null-Elements are added in the focusOrder-List by focusOrder.add(currentCell.getComponent()). That causes a catched Nullpointer Exception in CustomizableFocusTraversalPolicy.customizeFocusTraversalOrder() which is called from TableLayoutBuilder.installFocusOrder(list). The client property with the ordered list
of components will not be set and focus traversal will not work as expected. 

Fix: Don't add null-elements into the focusOrder List. A Workaround is to create placeholder cells with TableLayoutBuilder.cell(new JPanel()) instead of builder.cell().
