Perfect. The represented object is a NSString and contains directly 
the filetype. I cleaned up the code, it works fine and commited it.

I need to initialize my option controls, specifically I send an action 
to the compression ration slider, so it reads its value and sends it 
to the text field. I do this if" "JPEG" is selected, but not if "TIFF" 
since it is not needed.

At startup, the document type gets selected automatically, but it does 
not "perform" the action. So if it selects TIFF it is fine, but if it 
is already JPEG, the fields are uninitialized.
Perhaps I should check duing the file panel creation, but there I 
don't have the "sener", that is the popupbutton, to explicitely check 
for the type.

I don't doubt there are bugs lurking around.

On mac, if I do "save as" and "save as again" I get twice this log:

2012-10-07 11:13:37.651 PRICE[1316] prepareSavePanel, original 
accessory view class: NSBox
2012-10-07 11:13:37.666 PRICE[1316] original content view: <NSView: 
0x4692f0>
2012-10-07 11:13:37.669 PRICE[1316] new options view: <NSBox: 0x4d6840>

<...>

2012-10-07 11:13:48.188 PRICE[1316] prepareSavePanel, original 
accessory view class: NSBox
2012-10-07 11:13:48.188 PRICE[1316] original content view: <NSView: 
0x5828d70>
2012-10-07 11:13:48.188 PRICE[1316] new options view: <NSBox: 0x4d6840>

this means that the options view loaded from the nib is the same, but 
he view of the savepanel is different.

On GNUstep I ca't get anything to work at the moment, I expect I need 
some slight different reparent code, because the accessory view is not 
a Box, however right now I get "null" for the original content view. 
Does it work for  you?
