Sheet: Exception `org.primefaces.shaded.json.JSONException: JSONArray[0] is not a JSONArray` on events `columnSelect` and `rowSelect`

Describe the bug I took a look at the sheet component. But a JSONException is thrown when a column or row is selected.

Reproducer See showcase.

To Reproduce Steps to reproduce the behavior:

1. Go to Sheet -> Ajax events in the showcase.
2. Click on a column header or a row number.
3. See error:
