29d7dbc9 | 82 | * <h2>Pending issues:</h2> |
83 | * There is a general problem with the streaming of the digit tree. A description | |
84 | * is in the GetEvent function. For many events the hotfix for that caused bug | |
85 | * https://savannah.cern.ch/bugs/?72815 | |
86 | * This has been fixed by accessing the AliLoader in the CF component via the | |
87 | * global AliRunLoader. This breaks the idea of components, however it's used in | |
88 | * simulation inside AliRoot only. | |
