Re: [platform-ui-dev] AbstractTableViewer virtualSetSelectionToWidget()

Boris,

When I first looked at virtualSetSelectionToWidget(), I was hoping  
that it was supporting "virtual selection", but after looking at the  
code further, that appears to not be the case.  I hacked the code a  
bit, and came up with a solution that seems to support virtual  
selection, but it needs more work and testing.

Basically, I need a way to call viewer.setSelection() and not have the  
underlying TableItems created.
