Subject [jira] Created: (COCOON-2035) NPE in the sorter of the EnhancedRepeater

NPE in the sorter of the EnhancedRepeater
-----------------------------------------

                 Key: COCOON-2035
                 URL: https://issues.apache.org/jira/browse/COCOON-2035
             Project: Cocoon
          Issue Type: Bug
          Components: Blocks: Forms
    Affects Versions: 2.2-dev (Current SVN)
            Reporter: Gustavo N. Fernandes
         Attachments: SorterNullFix.patch

Steps to reproduce
===============

1. Execute the enhanced repeater sample at http://localhost:8888/blocks/cocoon-forms-sample/pagination/paginated.do
2. Click "Sort-by-name"
3. Click "Add player"
4. Click again "Add player"
5. Boom!

Causes
======
The sorter shipped wih EnhancedRepeater does not deals with situations where the value of
the field being compared is null

Suggestion proposed
===================
A new parameter nullsAreHigh (default=false) are passed to RepeaterJXPathSorter that will
check for nulls and will sort based on the 
parameter. NullsAreHigh=false means that nulls are lower than anything else.
