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
MessageDialog dialog = new MessageDialog( getSite( ).getShell( ),
										title,
										null,
										message,
										MessageDialog.QUESTION,
										buttons,
										0 );
								if ( dialog.open( ) == Dialog.OK )
								{
									doSaveAs( );
								}
								else
								{
									closeEditor( false );
								}
							}
						}
					} );
				}
				else
				{ 
					final IFile newFile = ResourcesPlugin.getWorkspace( )
							.getRoot( )
							.getFile( delta.getMovedToPath( ) );
					display.asyncExec( new Runnable( ) {
						public void run( )
						{
							FileEditorInput input = new FileEditorInput( newFile );
							setAllInput( input );
						}
