Jerome,

This is a new occurance of the problem Markus got last week.

Tobias, 
When I follow the steps, I select ITreeSelection, but nothing happens when I press OK (no Finish button).
I get "No possible update found" besides the ITreeSelection name.
Comment 2 Tobias Widmer CLA 2006-04-11 04:49:12 EDT 
Olivier,

This is by design. If you have ie. jdt.core in the workspace and JFace as binary, there are no type occurrences of TreeSelection which could be updated.

Otherwise, if there are opportunities to replace TreeSelection by ITreeSelection, please file a bug against JDT UI.
Comment 3 Markus Keller CLA 2006-04-11 05:50:34 EDT 
To reproduce, you also have to import org.eclipse.jdt.ui as source into your workspace (I got it in a clean N20060411-0010 with only these two projects).
