The documentation for external sorting / partial lists uses incorrect parameter name which could allow users to believe the functionality does not work.

The documentation for external sorting / partial lists indicates the following line of code should be used to determine the specific page that the displaytag has passed back to the request:

To determine the starting record you need to return based on the request parameters provided via Display Tag you can do:

(Integer.parseInt(request.getParameter((new ParamEncoder(tableId).encodeParameterName(TableTagParameters.PARAMETER_ORDER)))) - 1) * pageSize

I believe the correct parameter should be:

(Integer.parseInt(request.getParameter((new ParamEncoder(tableId).encodeParameterName(TableTagParameters.PARAMETER_PAGE)))) - 1) * pageSize
