[ROOT] problem with event class in the dictionary

  Hallo,
please help me with the event class in the dictionary.
I use root files create with classes ( I dont know how )

My program:
{

  f_input = TFile::Open("run100.root");
  TTree *t1 = (TTree*)f_input->Get("t1");

  const UShort_t MaxValues=10;
  UShort_t NumValues=0;
  UShort_t Values[MaxValues]={0};

  t1.SetBranchAddress("fbranch_NumValues",&NumValues);
  t1.SetBranchAddress("fXXX.fbranch_Values",Values);

  for (UInt_t i=0; i < t1.GetEntries(); i++)
  {
    t1.GetEntry(i);
    for (UShort_t j=0; j < NumValues; j++)
      {
 cout << Values[j] << endl;
      }
  }

}

In ROOT ver 3.03.09:
Warning in <TClass::TClass>: no dictionary for class XXXX1 is available
Warning in <TClass::TClass>: no dictionary for class XXXX2 is available

but all working.

Now I use ROOT ver 3.05.02,
after command line  t1.GetEntry(i);
