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.editors/src/org/eclipse/birt/report/designer/ui/editors/MultiPageReportEditor.java
{
			IEditorPart activeEditor = ( (FormEditor) getMultiPageEditor( ) ).getActivePageInstance( );
			if ( activeEditor != null )
			{
				ISelectionProvider selectionProvider = activeEditor.getSite( )
						.getSelectionProvider( );
				if ( selectionProvider != null )
					selectionProvider.setSelection( selection );
			}
			else
			{
				this.globalSelection = selection;
				fireSelectionChanged( new SelectionChangedEvent( this,
						globalSelection ) );
			}
		}
	}
	/**
	 * Constructor
	 */
	public MultiPageReportEditor( )
	{
		super( );
	}
