[news.eclipse.platform] Re: Common Navigator Content Issue

["Francis Upton (News)" <francisu@xxxxxxxx>]

getElements() returns an array of objects, each member of which is put 
into the underlying SWT tree.  I don't understand why your model objects 
extend ArrayList and what you are trying to accomplish there.  Normally, 
model objects are just normal objects which will appear in the navigator 
tree.

Can you give some more background about what you are trying to do?
