Description Axel Mueller CLA 2011-08-31 03:05:44 EDT 
Build Identifier: Indigo Build id: 20110609-2236, CDT 8.0.0

After upgrading from Helios to Indigo.
"Link to editor" works in Navigator but fails in Project Explorer and C/C++
Explorer. 
As described in https://bugs.eclipse.org/bugs/show_bug.cgi?id=320473#c14 it seems that the tree expansion does not work.

Bug only happens for C/C++ projects. No problem with simple resource projects.

Reproducible: Always
Comment 1 Anton Leherbauer CLA 2011-08-31 03:49:08 EDT 
It works for me with a sample hello world project.
Please provide a test case which fails reproducibly.
Do you have any other plugins installed except Eclipse and CDT?

It depends on the depth of the file tree.

src
  sub1
    file1-works
    sub2
      file2-works
      sub3
        file3-does_not_work
Comment 3 Anton Leherbauer CLA 2011-08-31 07:29:46 EDT 
Hm, still cannot reproduce. I tried on Windows and Linux, a variety of file types and file tree depths.
Is there maybe something in the log?

Sample project

- Import this project into your workspace and open it (do not expand project tree)
- Open Resource: Menu Navigate->Open Resource .. or Shift-Ctrl-R
  and select file1.cpp
=> file1.cpp should be opened in the editor but nothing happens in the Project Explorer

If it still does work as expected for you then close and reopen the project (close file1.cpp before).
Comment 5 Anton Leherbauer CLA 2011-08-31 09:06:42 EDT 
Still works for me.  I even installed AnyEdit Tools because the .settings in the sample project indicated that you have that installed, but still no change in behavior.

Preferences

I tried with a complete new workspace and my sample project does indeed work as expected. However, after importing the preferences from my actual workspace the problem occured. Unfortunately, I do not know which preference is the cause.

When I enable the preference C/C++ > Appearance > Show source roots at top of projects, it starts to fail.

Did you enable or disable it? It starts to fail for me when I disable the preference.

Yes, when I disable this preference (my default because of bug #355601 ) it fails. Enabling makes it work again.

You are right.  It's enabled by default and I disabled it.
