Well, I have found the problem AND a solution, maybe it will fix your problems, too.
Opened a bug report: http://issues.apache.org/jira/browse/MYFACES-229

Hope this helps. PROBLEM: Unimplemented methods in org.apache.myfaces.custom.datalist.HtmlDataList public void processUpdates(FacesContext context); public void processValidators(FacesContext context) SOLUTION: public void processUpdates(FacesContext context) { int first = getFirst();         int rows = getRows();         int last;         if (rows == 0)         {             last = getRowCount();         }         else         {             last = first + rows;         }         for (int rowIndex = first; rowIndex < last; rowIndex++)         {             setRowIndex(rowIndex);             if (isRowAvailable())             {                 for (Iterator it = getChildren().iterator(); it.hasNext();)                 {                     UIComponent child = (UIComponent)it.next();                     if (!child.isRendered())                     {                         continue;                     }                     child.processUpdates(context);                 }             }         }         setRowIndex(-1); } public void processValidators(FacesContext context) { int first = getFirst();         int rows = getRows();         int last;         if (rows == 0)         {             last = getRowCount();         }         else         {             last = first + rows;         }         for (int rowIndex = first; rowIndex < last; rowIndex++)         {             setRowIndex(rowIndex);             if (isRowAvailable())             {                 for (Iterator it = getChildren().iterator(); it.hasNext();)                 {                     UIComponent child = (UIComponent)it.next();                     if (!child.isRendered())                     {                         continue;                     }                     child.processValidators(context);                 }             }         }         setRowIndex(-1); }
