setSortOrderings? -A dirty solution-

There were two problems indeed:
1. How to create the NSSelector with name CompareDescending (a static 
value of EOSortOrdering).
2. There are two classes named NSArray; one in the pakage 
com.apple.cocoa.foundation and the other in com.webobjects.foundation; 
worse, they are not compatible and the morphing of the Java-bridge does 
not work well in this case.

So, I had to create a java class and call it from my ObjC class with 
the following code (if some one find a better ---purely ObjC--- 
solution, please let me know):

public class Util {

     public Util(){
         super();
     }

     public EOSortOrdering sortOrderingDescending(String key){
         return (EOSortOrdering)EOSortOrdering.sortOrderingWithKey(key, 
EOSortOrdering.CompareDescending);
     }

     public void setSortOrdering(EODisplayGroup dg, EOSortOrdering so){
         com.webobjects.foundation.NSArray nsa = new 
com.webobjects.foundation.NSArray(so);
         dg.setSortOrderings(nsa);
     }

}

@interface AlmacenA : NSObject
{
     IBOutlet id dgArt;	// EODisplayGroup
     IBOutlet id util;	// Util.java
}

@implementation AlmacenA

- (void)awakeFromNib
{
     id so = nil;

     so = [util sortOrderingDescending:@"detalle"];
     [util setSortOrdering:dgMov :so];

}


I hope there are still developer in Apple trying to bring back 
Cocoa/EOF apps into support and, may be some one else, try to fix these 
errors (bugs?).
