WOSortOrder and its alt binding

[Javier Pena]

Hello,

In WO 4.0 the WOSortOrder component now has the method helpString  
bind to the alt binding of the WOActiveImage instead of just the word  
"Order" like in WO 3.51.  For some reason this method returns the  
string "Push to toggle sorting order according to *nil*".  I don't  
mind the long string, I just don't like the word *nil* in it.  I know  
I can steal the .wos code in 3.51 (in 4.0 I think it is now compiled  
because there is no .wos anymore inside the .wo) and change the code  
to whatever I want, but before taking that route I wonder if I'm  
doing something wrong.

This is how I define the WOSortOrder in my .wod

SortButton: WOSortOrder {
        key = keyForCurrentObject;
        displayGroup = displayGroup;
}

keyForCurrentObject is a method.  When I click the button the  
sorting works perfectly which means that this method is returning the  
right key and not nil.

Any ideas?

Thanks in advance
