Memory leak with extended data table after repeated rerender
------------------------------------------------------------

                 Key: RF-8275
                 URL: https://jira.jboss.org/jira/browse/RF-8275
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-tables
    Affects Versions: 3.3.2.SR1
         Environment: Windows xp and AIX, Firefox and Internet Explorer 7
            Reporter: Manuele Piastra
            Priority: Critical

After each rerender of the extended data table the memory allocated to the process iexplorer.exe keeps growing and it is never released. The same test with simple datatable doesn't show this problem.

Snippet code used for the test
