Bug 116706 Bad Class Cast in IDEReportEditor.java
So I'm trying to open a report with BIRT/Eclipse API using the BIRT 2.0 nightly build code (as of 11/16/2005). the file IDEReportEditor.java method private IFile getFile( IEditorInput input ) { return ( (ReportFileEditorInput) input ).getFile( ); } However, input can be ReportEditorInput which is also an IEditorInput (to support reports found outside projects and workspaces) which doesn't even have a getFile() method on it. This causes a deeply nested exception that causes the report desinger to not be able to show a report that might be physically located outside a workspace.
UI/org.eclipse.birt.report.designer.ui.rcp/src/org/eclipse/birt/report/designer/ui/internal/rcp/dialogs/SaveAsDialog.java
String question = Messages.getFormattedString( "SaveAsDialog.overwriteQuestion", 
					new Object[]{
						path.toOSString( )
					} );
			MessageDialog d = new MessageDialog( getShell( ),
					Messages.getString( "SaveAsDialog.Question" ), 
					null,
					question,
					MessageDialog.QUESTION,
					buttons,
					0 );
			int overwrite = d.open( );
			switch ( overwrite )
			{
				case 0 : 
					break;
				case 1 : 
					return;
				case 2 : 
				default :
					cancelPressed( );
					return;
			}
		}
		
		result = path;
		close( );
	}
}
