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.

{
			groupHandle = factory.newListGroup( );
			slotHandle = ( (ListHandle) parent ).getGroups( );
		}
		if ( groupHandle != null && slotHandle != null )
		{
			slotHandle.add( groupHandle, position );
			
			{
				GroupDialog dialog = new GroupDialog( getDefaultShell( ),
						GroupDialog.GROUP_DLG_TITLE_NEW );
				dialog.setDataSetList( DEUtil.getDataSetList( parent ) );
				dialog.setInput( groupHandle );
				if ( dialog.open( ) == Window.CANCEL )
				{
					return false;
				}
			}
			return true;
		}
		return false;
