Bug 120291 Data source and data set extended from library in a report are invalid.
Description: Data source and data set extended from library in a report are invalid. Steps to reproduce: 1. Drag a data source and data set from library explorer view. Noticed that their names are different from the names in library. 2. I want to use the data source extended from library to create a new data set. The data source is invalid. 3. The data set from library is also invalid. When editing it, NullPointerException is thrown out.
