Summerian commented on DISPL-390:
---------------------------------
I managed to achieve workaround via Decorators:
- table decorator to set in request current page number
- row decorator, to display in cell row number plus offset computed off page
number
public class RownumTableDecorator extends TableDecorator {
public void init(PageContext pageContext, Object decorated, TableModel
tableModel) {
super.init(pageContext, decorated, tableModel); //To change body of
overridden methods use File | Settings | File Templates.
Integer pageNumber = 1;
try {
pageNumber =
Integer.parseInt(pageContext.getRequest().getParameter(new
ParamEncoder(tableModel.getId()).encodeParameterName(TableTagParameters.PARAMETER_PAGE)));
} catch (NumberFormatException e) {
//e.printStackTrace(); //To change body of catch statement use
File | Settings | File Templates.
} catch(NullPointerException e){
//
}
pageContext.getRequest().setAttribute("my_pagenumber", pageNumber);
}
}
public class RownumDecorator implements DisplaytagColumnDecorator {
public Object decorate(Object columnValue, PageContext pageContext,
MediaTypeEnum media) throws DecoratorException {
Integer myRownum = (Integer)
pageContext.getRequest().getAttribute("my_rownum");
if(myRownum == null){
myRownum = 0;
}
Integer pageNumber = (Integer)
pageContext.getRequest().getAttribute("my_pagenumber");
if(pageNumber == null){
pageNumber = 1;
}
myRownum++;
pageContext.getRequest().setAttribute("my_rownum", (myRownum));
return (pageNumber-1) * 10 + myRownum;
}
}
<display:table name="raportList" pagesize="10" decorator="RownumTableDecorator">
<display:column title="Row number" decorator="RownumDecorator"/>
</display:table>
> _rowNum doesn't change after a sort
