Gorm, NSCollectionView

[forumer]

Hi,

I would lile to open a xib file created under Xcode and that has an 
empty NSCollectionView, how can I slightly
modify the GSXibKeyedUnarchiver to ignore this object or to display a 
dummy view ?
Here is an extract of the xib file :

<object class="NSScrollView" id="484370537">
    <reference key="NSNextResponder" ref="462115558"/>
    <int key="NSvFlags">-2147483382</int>
    <object class="NSMutableArray" key="NSSubviews">
        <bool key="EncodedWithXMLCoder">YES</bool>
        <object class="NSClipView" id="204776699">

</object>

Actually my goal is only to see what this xib file looks like inside 
Gorm and not to edit or change any properties.
Could it be done by a quick and dirty hack ?
Could I substitute the NSCollectionView by a NSCustomView during xml 
parsing ?

I am fed up with switching between my pc and my mac mini ...

Thanks
