[cdt-patch] Partially address bug43130

[Andrew Niefer <aniefer@xxxxxxxxxx>]

bug43130- Selected Resources is disabled but selected.

This is an eclipse framework bug, so all we can do is handle the case when 
it happens.

ui :
-modified CSearchPage.performAction()

no tests with this patch, its all UI.
(automated tests still pass on windows)
