Bug 40830 hierarchy view not up to date after rename [type hierarchy]
If you use the standard java perspective layout and have the following file --------------------------------A.java------------------------ public class A { } class B extends A { } -------------------------------------------------------------- double click on the first 'A' and press F4 (hierarchy view) then click on the package explorer (so as to hide the hierarchy view). then rename the class A to class C (using refactoring) double click on the new class name and click F4 the hierarchy still displays with 'A' at the root and not the new name ('C')
