Comment 3 Alexander Simon 2010-12-09 09:05:18 UTC 
Thomas, before closing issue you should proof that in ordinary work flow it cannot be. See code TableEditorPanel.MyTable.getCellEditor():
------------8<------------------
            } else if (col == 1) {
                LibraryItem.ProjectItem projectItem = (LibraryItem.ProjectItem) listData.elementAt(row);
                Project project = projectItem.getProject(baseDir);
                if (project == null) {
                    return super.getCellEditor(row, col);
                } else {
                    MakeArtifact[] artifacts = MakeArtifact.getMakeArtifacts(project);
                    JComboBox comboBox = new JComboBox();
                    for (int i = 0; i < artifacts.length; i++) {
                        comboBox.addItem(new MakeArtifactWrapper(artifacts[i]));
                    }
                    return new DefaultCellEditor(comboBox);
                }
------------8<------------------
Are you sure that combobox will have not empty item list?
If you can proof it, close bug.
OK, simplest way to reproduce bug is:
- create sub-project application
- restart IDE
- open in editor hello1lib/nbproject/configuration.xml
- type "-" in line 2 after "<", save file, project hello1lib is broken
- edit main project properties->Linler->Libraries
- click on hello1lib Configuration column
- try to click on any other cell, see NPE

OK, I able to reproduce it now. It would have been very helpful if you had included the steps in the first place. Will fix.....
