[Mono-osx] outlineViewWillDisplayCell Issues

I have an NSOutlineView and I connect the delegate to the correct class and
then implement the following method:

[Export ("outlineView:willDisplayCell:forTableColumn:item:")]
public void outlineViewWillDisplayCell(NSOutlineView outlineView, NSObject
*cell*, NSTableColumn tableColumn, NSObject item)

The problem I have is that sometimes *cell* is null. I can handle this by
checking for a null value but the outline view is then not displayed
properly (it's almost as if it is drawn with a cached image and no text).

Why would a null value be passed when it is attempting to draw a particular
cell? Is there any way around this, or possibly something that I might be

Apologies if this has already been addressed, I could not find anything
during search.
