Entered values for input fields conatined in a Composite Component are lost, if the CC is used
in a datatable
-------------------------------------------------------------------------------------------------------------

                 Key: MYFACES-3385
                 URL: https://issues.apache.org/jira/browse/MYFACES-3385
             Project: MyFaces Core
          Issue Type: Bug
    Affects Versions: 2.1.2
            Reporter: Michael Dietrich
         Attachments: MyFacesCCUIData212Test.war

Assume, a Composite Component contains input fields, i.e any subclass of EditableValueHolder
(e.g. inputText, inputTextarea, ..). If this CC is than used in a subclass of UIData, e.g.
a dataTable, the values entered in the CCs input fields get lost (despite for the last row
in the Model of the UIData object).

This seems to be related to the fact how the method "saveDescendantComponentStates(..)" of
the UIData class checks, if a component has childs, whos state must be saved, before changing
the rowIndex. The mentioned method only checks "child.getChildCount() > 0", but getChildCount()
is 0 for a CC. I assume it would be necessary to check the FacetCount for a CC instead. 

The attached WAR file can help to reproduce the issue with a simple example.
