UIDataAdaptor vs. UIData visitTee small difference
--------------------------------------------------

                 Key: RF-10154
                 URL: https://issues.jboss.org/browse/RF-10154
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-tables
    Affects Versions: 4.0.0.Milestone5
         Environment: RichFaces 4.0.X trunk, svn rev. 20913
            Reporter: Martin Kočí
            Priority: Minor


<r:extendedDataTable var="zeile">
<r:column>
  <h:outputText rendered="#{fasole.method(zeile)}"
</r:column>
</r:extendedDataTable>
+
 org.richfaces.component.UIDataAdaptor.visitTree(VisitContext, VisitCallback) with VisitHint SKIP_UNRENDERED (in render response phase for example)

Problem: org.richfaces.component.UIDataAdaptor.visitDataChildren(VisitContext, VisitCallback, boolean) calls visitComponents(getFacetsAndChildren(), visitContext, callback);-> it will visit h:outputText component and test if is rendered -> #{fasole.method(zeile)} but no row available -> calls fasole.method with null parameter and causes an unexpected NPE

j.f.c.UIData does not visit column chidren for -1 rowIndex (null rowKey in RichFaces), UIData.visitTree JavaDoc says: "Take no action on non-UIColumn children".
