Why doesn't gwt CellTable show all the results?

I get the list of results using rpc call. I sure that result list is correct because when I use dialog box all data is there. But when I put it in CellTable some rows lost. Why does this happen?

public void onSuccess(List<List<String>> result) {  
            CellTable<List<String>> bugsTable = new CellTable<List<String>>();
            // Create columns
            TextColumn<List<String>> idColumn = new TextColumn<List<String>>() {
              @Override
              public String getValue(List<String> recordSet) {
                return recordSet.get(0).toString();
              }
            };

            TextColumn<List<String>> idCommitColumn = new TextColumn<List<String>>() {
              @Override
              public String getValue(List<String> recordSet) {
                  return recordSet.get(1).toString();
              }
            };

            TextColumn<List<String>> erMessageColumn = new TextColumn<List<String>>() {
              @Override
              public String getValue(List<String> recordSet) {
                  return recordSet.get(2).toString();
              }
            };

            // Add the columns.
            bugsTable.addColumn(idColumn, "ID");
            bugsTable.addColumn(idCommitColumn, "ID commit");
            bugsTable.addColumn(erMessageColumn, "Message");

            // Set the total row count. This isn't strictly necessary, but it affects
            // paging calculations, so its good habit to keep the row count up to date.
            bugsTable.setRowCount(result.size(), true);

            // Push the data into the widget.
            bugsTable.setRowData(0, result);
            tabP.add(bugsTable, "bugs");
            RootPanel.get("loadingbarImg").setVisible(false);
        }
    });

The default ProvidesKey (SimpleKeyProvider) uses objects themselves as keys, so their equals() and hashCode() are used. The java.util.List contract defines the equals() and hashCode() behaviors, and mandates that two lists with the same items will be equals() and have the same hashCode(), so if you have some identical rows in your list, it could be a problem.

Solution: don't use List<String> for your rows, define a specific row class instead.
