This problem should now be fixed in the CVS repository.

Cheers,
Philippe.

Investigating the reasons I found out that when CollectionTree is clicked in the ROOT browser, there is infinitive loop after 'mcEtIsol' branch element involving the methods TNonSplitBrowsable::GetBrowsables and TStreamerSTL::IsBase(). We will investigate further.

Thank you for your reply. I see no problem accessing the tree via GUI also. After the executing the lines:
root [0] gSystem->Load("/afs/cern.ch/sw/lcg/app/releases/POOL/POOL_2_4_4/slc3_ia32_gcc323/lib/liblcg_RootCollection.so")
(int)0
root [1] TFile f("/afs/cern.ch/user/t/tmaeno/public/AANTuple.root")
root [2] TTree *t = f.Get("CollectionTree")
root [3] TBrowser b

please click with the right-mouse button on the CollectionTree and select from the context menu the entry 'StartViewer'. After that the TreeViewer application shows up and you can use it to examine the tree.

Of course I agree that clicking on the tree object should not hang the root session and we will investigate this case.

Cheers, Ilka

AttributeListLayout is a schema. ROOT version of Registration stream in
POOL requires it to expand attributes. It was written at

http://alxr.usatlas.bnl.gov/lxr/sou...

I'm not sure if AttributeListLayout is guilty, because I don't find any
problems when accessing the tree in the command-line environment.
Thanks,

Hi,

I see that the shared library needed in this case is related to POOL (/afs/cern.ch/sw/lcg/app/releases/POOL/POOL_2_4_4/slc3_ia32_gcc323/lib/liblcg_RootCollection.so ) and the root file contains
root [3] f.ls()
TFile** /afs/cern.ch/user/t/tmaeno/public/AANTuple.root
TFile* /afs/cern.ch/user/t/tmaeno/public/AANTuple.root
KEY: AttributeListLayout Schema;1
KEY: TTree CollectionTree;1 CollectionTree
root [4] f.Map()

You might help us saying how the root file was created and what is the purpose of AttributeListLayout.

Thank you, Ilka

Thanks for looking into this. The warning message has gone when
a shared lib is loaded. But the hang is still there;

[tmaeno@lxplus061 tmaeno]$ root.exe
root [0] gSystem->Load("/afs/cern.ch/atlas/offline/external/LCGCMT/LCGCMT_43C/InstallArea/i686-slc3-gcc323-opt/lib/liblcg_RootCollection.so");
root [1] TFile *_file0 = TFile::Open("/afs/cern.ch/user/t/tmaeno/public/AANTuple.root")
root [2] TBrowser t

open the file and click CollectionTree -> ROOT hangs up.

Here is my LD_LIBRARY_PATH.

[tmaeno@lxplus061 cmt]$ echo $LD_LIBRARY_PATH
/lib:/afs/cern.ch/user/t/tmaeno/Offline/12.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/software/builds/AtlasOffline/12.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/software/builds/AtlasAnalysis/2.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/software/builds/AtlasTrigger/2.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/software/builds/AtlasReconstruction/2.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/software/builds/AtlasEvent/2.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/software/builds/AtlasConditions/2.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/software/builds/AtlasCore/2.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/offline/external/Gaudi/0.16.1.13-LCG43C/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/offline/external/LCGCMT/LCGCMT_43C/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/software/builds/DetCommon/2.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/atlas/software/builds/AtlasSimulation/2.0.3/InstallArea/i686-slc3-gcc323-opt/lib:/afs/cern.ch/sw/lcg/external/Python/2.4.2/slc3_ia32_gcc323/lib:/afs/cern.ch/sw/java/i386_redhat73/jdk/sun-1.5.0/jre/lib/i386:/afs/cern.ch/sw/java/i386_redhat73/jdk/sun-1.5.0/jre/lib/i386/client:/afs/cern.ch/sw/java/i386_redhat73/jdk/sun-1.5.0/jre/lib/i386/native_threads:/afs/cern.ch/sw/java/i386_redhat73/jdk/sun-1.5.0/jre/lib/i386/xawt

Please read the last sentence of my previous message: "I see no problem reading other root files and using the ROOT browser"

Thanks, Ilka

Hi,

I can reproduce the reported case, but I see in addition the following messages:
"Warning in <TClass::TClass>: no dictionary for class AttributeListLayout is available
Warning in <TClass::TClass>: no dictionary for class pair<string,string> is available"

related to what you have saved in the root file:
root [1] f.ls()
TFile** /afs/cern.ch/user/t/tmaeno/public/AANTuple.root
TFile* /afs/cern.ch/user/t/tmaeno/public/AANTuple.root
KEY: AttributeListLayout Schema;1
KEY: TTree CollectionTree;1 CollectionTree

So, the problem might be not related to the GUI and the ROOT Object browser because I see no problem reading other root files.

Cheers, Ilka

[tmaeno@lxplus060 tmaeno]$ which root.exe
/afs/cern.ch/sw/lcg/external/root/5.10.00e/slc3_ia32_gcc323/root/bin/root.exe
[tmaeno@lxplus060 tmaeno]$ root.exe /afs/cern.ch/user/t/tmaeno/public/AANTuple.root
...
root [1] CollectionTree->Show(1)
...
TimeStreamAOD = 250
TimeCBNT_AthenaAware = 1130
TimeAANTupleStream = 70

I can read the tree on the command-line. Then

root [2] TBrowser t

when I open the file and click CollectionTree, ROOT hangs up.
Thanks,
