silly issue when using ITreeContentProvider [message #327374]

My model consists of a hierarchy of nodes. I find it cumbersome to make
a tree viewer display the tree rooted at a model element:

myNode
+ child1
+ child 2
....

It seems the api makes it easy to display only the children:

viewer.setInput(myNode);

shows

+child1
+child2

.....

I'd like the content provider to be able to do the following:

public Object[] getElements(Object inputElement) {

return new Object[] { inputElement };
}

Can I do this without wrapping inputElement into a another class?

thanks

There was a recent thread on this (could be on rcp or swt newsgroup
though) and even a bug report. The short answer is no you can't.
