Hello, I've managed to get the displayTag paging from my server side very nicely using an implementation of the PaginatedList interface. It all works very well and is pretty straight forward apart from getting the column sort functionality to work. The order doesn't change from sort=asc on the request when the user clicks the title link spin button.
I have searched the archives but only found this trail http://sourceforge.net/mailarchive/message.php?msg_id=4206234.249318%40sourceforge.net Its exactly the same problem as I am having. The root of the problem is that I don't understand how displayTag changes the SortOrderEnum it gets back from the PaginatedList getSOrtDirection(). In my spring-mcv controller I get the sorting direction from the request like this [code] String sortDirection = ServletRequestUtils.getStringParameter(httpServletRequest, "dir"); [/code] Then I create my PaginatedListImpl class and set the sortDirection String field with the value I just got from the request. In my getList() method of my PaginatedListImpl I get the limited list from the DAO and reverse it according to the sortDirection. Nice and simple, No problems there. In my PaginatedList impl I have the following for the getSortDirection: [code] if(sortDirection.equals("desc")) return SortOrderEnum.ASCENDING; else return SortOrderEnum.DESCENDING; [/code] Now here's the part I don't understand. DisplayTag calls the getSortDirection() when it renders to work out which order to place on the request when the user clicks the spin button. I know this because I followed the advice in the thread linked above and when I change what the getSortDirection() returns the initial page loads up with either the top or bottom spin button highlighted and either sort='asc' or sort='desc' on the request. When my PagintedListImpl gets the String 'desc' from the request the getSortDirection() method will return SortOrderEnum.ASCENDING, when its 'asc' it will return SortOrderEnum.DESCENDING But......why doesn't displaytag get the opposing SortOrderEnum object I return depending upon what I get from the request and change the highlighted spin button???????????????? Its very annoying, I guess I haven't understood how DisplayTag deals with the SortOrderEnum it gets from getSortDirection() correctly. The rest of the PaginatedList implementation seems very straight forward except for this, so I am sure I have misunderstood how I should implement the sorting part. Any advice or help would be much appreciated, I've spent two days hitting spin buttons now! Many thanks.
