Binding EOF Fecth Qualifier in IB

Hi there,

I'm an old NeXT developer, getting back into OSX. My question
may sound easy, but I couldn't find "how to" on the web, so here I post.

I'm writing a Obj-C/Cocoa application that uses EOF (No lines of code up to
now so Obj-C doesn't matter)

Here is what I want to do: a search form in a database (containing millions
of entries, so I can't select all, then search in memeory) using
Appkit/Interface Builder. The database was designed using EOF/EOModeler.
I have added a Fetch Specification to may table, with a Qualifier:

    name = $name

Once under IB, I just can't find how to link some NSTextField or NSForm to
the Qualifier Variable.

Though, Apple doc says

http://developer.apple.com/documentation/WebObjects/UsingEOModeler/8WorkingW
ithFetchSpecifications/chapter_8_section_2.html

" You do this by dragging a fetch specification into either WebObjects
Builder or Interface Builder and then binding user interface elements to
keys in the display group that correspond to the fetch specification¹s
variables "

"In Interface Builder, the steps are similar except that you bind the user
interface elements to @bindings.title, @bindings.date, and
@bindings.studioName keys of your display group. The @bindings syntax
represents the value associated with the named qualifier variable"

I got a new EODisplayGroup object configured with my Fecth Spec, but
I can't find anything related to @bindings or (@querybindings) in the
inspector of my NSFormCell inspector
(connections/EOTextAssociation/EOPickTextAssociation), nor in the inspector
of my EODisplayGroup.

Last thing: I understand how to make it programmatically, but I want to
do it under IB

I think it should be as easy as a 2 click operation (like browsing all
entries and adding new entries in DB), but couldn't find how to! Plz help!

Regards,

    Ryu
