in my previous Controller.rb, i've added :

require 'OutlineViewProxyClass.rb'
include NSOutlineViewable             # probably not usefull ?

i've transformed each bookmark to bookmark.slave  seems to be no =20
probs here.

However for "def outlineView_child_ofItem(aTree, index, bookmark)" =20
i've done :

return @folder.to_nsobj if bookmark.class =3D=3D NilClass  # case of =
root =20
element @folder being a REXML::Element

children =3D bookmark.slave.get_elements("*")
return children[index].to_nsobj


and i get an error :

/Users/yvon/work/RubyCocoa/BookmarksMerge/build/Development/=20
BookmarksMerge.app/Contents/Resources/OutlineViewProxyClass.rb:14:in =20
`NSApplicationMain': NSApplicationMain - RBException_TypeError - =20
can't convert REXML::Element into Integer (OSX::OCException)
	from =
/Users/yvon/work/RubyCocoa/BookmarksMerge/build/Development/=20
BookmarksMerge.app/Contents/Resources/rb_main.rb:44


OutlineViewProxyClass.rb:14 being :

     ObjectSpace._id2ref(@slave) # used to prevent GC cycle

quiet, that's the first time i'm using a proxy ;-)

then i'm not sure on how to use it ))


best,
