[displaytag-user] how to get sort column, page number, etc in external sort if selected columns are returned

[Lixin Chu]

Hi,

is there a way to get page # and sort column info in external paging/sorting when only selected columns are returned from database ?

 

if the whole class is returned, we can use:

  String param = new ParamEncoder (".......").encodeParameterName(TableTagParameters.PARAMETER_PAGE);
  String page = (String) request.getParameter(param);

 

to get the page number; but what if the data I pass to Displaytag has selected columns not the whole class ? what should I put in ParamEncoder ?

 

thanks !
