Bug 193913 Adding a aggregate with a column binding name that already exists should display a proper message
Build ID: 2.2RC3 Steps To Reproduce: 1.Add table to report 2.Add aggregation to table (Column Binding Name = "TEST") 3.Remove aggregate from table (the binding remains in the list of column bindings for this table) 4.Try to add the same aggregate to table (Column Binding Name = "TEST") This causes the error as shown below: An unexpected internal exception occurred.Please see log for detail. Plug-in Provider:Eclipse.org Plug-in Name:BIRT Designer UI Plug-in ID:org.eclipse.birt.report.designer.ui Version:2.2.0.v20070613 Error Code:Error.GUIException.invokedByUnexpectedException Error Message:Caused by java.lang.NullPointerException. It should rather display a message that the binding already exists or just use the available binding for this aggregate. More information:
