Grid nested in horizontal layout generated, but not displayed completely

I am trying to put vertical layout next to grid within one horizontal layout.

public class SprinklerDetailUI extends VerticalLayout {

    private final VerticalLayout nozzleDetailLayout;
    private final TextField nozzleName;
    private final TextArea nozzleDescription;
    private final TextField fitForSprinkler;

    private final Grid<FlowSetEntity> flowGrid;
    private final HorizontalLayout nozzleFlowLayout;

    private final Nozzle nozzle;

    List<FlowSetEntity> flowSetEntities = Stream.of(new FlowSetEntity(10, 4),
            new FlowSetEntity(10, 4),
            new FlowSetEntity(23, 35),
            new FlowSetEntity(534, 10),
            new FlowSetEntity(654, 53))
            .collect(Collectors.toList());

    public SprinklerDetailUI() {

        this.nozzleName = new TextField("Nozzle name");
        this.nozzleDescription = new TextArea("Description");
        this.fitForSprinkler = new TextField("Fit for sprinkler");
        this.nozzleDetailLayout = new VerticalLayout(nozzleName, nozzleDescription, fitForSprinkler);

        this.nozzle = new Nozzle();
        nozzle.setFlowSet(flowSetEntities);

        this.flowGrid = new Grid<>(FlowSetEntity.class);
        flowGrid.setColumns("pressure", "flowRate");
        flowGrid.setItems(nozzle.getFlowSet());
        flowGrid.setSizeFull();

        this.nozzleFlowLayout = new HorizontalLayout(nozzleDetailLayout, flowGrid);
        nozzleFlowLayout.setSizeFull();
        add(nozzleFlowLayout);
    }
}

FlowSetEntity.class

@Entity
@Getter
@Setter
@NoArgsConstructor
public class FlowSetEntity implements Comparable<FlowSetEntity> {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    private double pressureInAtm;

    private double flowRateInLPM;

    @Transient
    private Quantity<Pressure> pressure;

    @Transient
    private Quantity<FlowRate> flowRate;

    @ManyToOne(optional = false)
    private Nozzle nozzle;

    public FlowSetEntity(double pressureInAtm, double flowRateInLPM) {
        this.pressureInAtm = pressureInAtm;
        this.flowRateInLPM = flowRateInLPM;
        this.pressure = toAtm(pressureInAtm);
        this.flowRate = toLPM(flowRateInLPM);
    }

    @Override
    public int compareTo(FlowSetEntity o) {
        int pressureCompare = Double.compare(this.pressureInAtm, o.pressureInAtm);
        int flowCompare = Double.compare(this.flowRateInLPM, o.flowRateInLPM);
        return pressureCompare != 0 ? pressureCompare : flowCompare;
    }
}

Generated page looks like this:

browser view

I seems that grid structure is generated correctly, but for some reason it is not displayed completely. When displaying same grid in vertical layout everything is fine.

Based on that UI code my guess is you're simply lacking a height on the outermost VerticalLayout. That means the height of the HorizontalLayout inside it, and the Grid inside that, is set to be 100% of nothing.

The form next to the Grid renders correctly because it doesn't define a height, and the containing HorizontalLayout gets an intrinsic height to accommodate that form, but the 100% on the Grid is still evaluated against the defined height which is missing, because css.
