Re: Binding query variables (EOF Fetch Spec Qualifier) under IB

Hola!

Since you are using Cocoa/eof the best you can do is forget about WO...
that is, you are dealing with a client/server app.
Secondly; you most remember that, behind the scenes, you are using the  
so-called Java-Bridge; therefore, you most know how does it translates  
objects from one side to the other. In particular you most be aware  
that those objects which come from com.webobjects.* do not translate  
naturally into those which are "related" to com.apple.*. In particular,  
what you seems to need is to distinguish from the  
com.webobjects.foundation.NSDictionary and the  
com.apple.foundation.NSDictionary: they are *different* kind of  
objects.

Take a look to
http://wodev.spearway.com/cgi-bin/WebObjects/WODev.woa/wa/Main? 
wikiPage=CocoaEOApplication

to read about some hints on the subject... and let me know if you need  
more help.

HIH
Dino
