I wondered why my ItemProvider didn't display any text in a table
viewer. It implements all required interfaces. I was so sure it should
work because I remember to have read (i think in "the book") that the
base implementation simply delegates to the base labelprovider's
getText() method, so all columns show the same text. And I remember to
have seen this in generated editors..
Now, (2.5, latest milestone), the method returns the empty String! Why
did it change?
