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.ide/src/org/eclipse/birt/report/designer/ui/editors/IDEMultiPageReportEditor.java
return;
		if ( !( (IFileEditorInput) getEditorInput( ) ).getFile( ).exists( ) )
		{
			Shell shell = getSite( ).getShell( );
			String title = DLG_SAVE_TITLE;
			String message = DLG_SAVE_CONFIRM_DELETE;
			String[] buttons = {
					DLG_SAVE_BUTTON_SAVE,
					DLG_SAVE_BUTTON_CLOSE
			};
			MessageDialog dialog = new MessageDialog( shell,
					title,
					null,
					message,
					MessageDialog.QUESTION,
					buttons,
					0 );
			if ( dialog.open( ) == 0 )
			{
				doSaveAs( );
				partActivated( part );
			}
			else
			{
				closeEditor( false );
			}
		}
	}
