Description Kent Johnson CLA 2003-11-28 16:20:32 EST 
M5

Start by adding the project org.eclipse.jdt.ui.examples.javafamily to your 
workspace.

1. Now open a type hierarchy on the package org.eclipse.search.internal.core 
from the source folder coresearch-experiment. Notice that some types such 
AndQuery are not there.

2. Select both packages in the source folder coresearch-experiment. Notice 
that 'Open Type Hierarchy' is not a choice on the menu... but if you select the 
source folder coresearch-experiment, it is available.

These are two different issues:

1.) this is very likely a core issue

2.) UI should support multiple homogenous selections.
Comment 2 Martin Aeschlimann CLA 2003-12-01 12:41:05 EST 
Reproduced. Seems to be a problem in the type hierarchy:
The hierarchy should contain children for 'InternalSearchQuery'

For point 2., this works as designed, the type hierarchy view does not support 
multiple inputs. Please file a feature request. Moving this bug to JDT core.
Comment 3 Jerome Lanneluc CLA 2003-12-17 09:48:58 EST 
RegionBasedTypeHierarchy.pruneDeadBranches() consider that a branch is dead as 
soon as one type of this branch is not part of the region. 

Should fix to consider that a branch is dead if all types of the branch are not 
part of the region.
Comment 4 Jerome Lanneluc CLA 2004-01-07 07:12:32 EST 
Fixed pruneDeadBranches() and added regression tests 
TypeHierarchyTests.testRegion1() and testRegion2()
