[pribavkindenis]

Minimal reproducible example:

   tipsPivotTable.addCellClickListener(event -> {
       // Your implementation here    
   });

3. Start the application.
4. Open Pivot Table screen.
5. Open Tips tab.

6. Click on the cell pointed by the green arrow.

  CellClickEvent provides DataItem objects each of them contains TipInfo object satisfies the following conditions:

  sex == "Female"
  smoker == true
  day == "Fri"
  time == "Dinner"

• Actual behavior:

  CellClickEvent does not provide DataItem objects.
