Hello Christian
I can not test version 3 at the moment.
However with version 2.25 it works:
*******************************************
* *
* W E L C O M E to R O O T *
* *
* Version 2.25/01 8 August 2000 *
* *
* You are welcome to visit our Web site *
* http://root.cern.ch *
* *
*******************************************
root.exe [13] TString a("~/public/expert")
root.exe [14] TFileSet fs(a)
root.exe [15] fs.ls(8)
0 - expert directory
1 - expert/Jeff directory
2 - expert/Jeff/SavePrim.C file
2 - expert/Jeff/myTestFile.C file
1 - expert/C++Fun directory
2 - expert/C++Fun/base1.h file
2 - expert/C++Fun/base2.cxx file
1 - expert/Leaks directory
I'll test version 3 as soon as BNL computers are back
to do something useful.
Can you test your example with that version now ?
