IllegalArgumentException：数据网格 primefaces 中不支持的每页行数

Question

早上好，我是 jsf 的新手，我想将属于由视图参数传递的 Marca（品牌）的产品放入数据网格，这是一些 jsf 代码

<f:view>

    <f:metadata>
         <f:param name="id"  value="#{marcaController.id}" scope="request"></f:param>
    </f:metadata>
</f:view>

    <ui:composition template="template/template1.xhtml">

        <p:messages id="messages"/>
            <p:dataGrid var="product" value="#{prodottoController.finbyMarca(marcaController.id)}"  columns="3" layout="grid"

这是马卡报控制器

@Named
@ViewScoped
public class MarcaController implements Serializable {
    private static final long serialVersionUID = 1L;
    String id;
    Marca m=new Marca();
    @EJB
    private MarcaDao marcaDao;

    @PostConstruct
    public void initialize() {
        id = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("id");
    }
    
    public Marca getSelected() {
        return m;
        
    }
    public void seteSelected(Marca m) {
        this.m=m;
    }
    
    public List<Marca> listAll() {
        return marcaDao.listAll();
    }
    
public String getId(){  
        return idm;
    }
public void setId(String i){
    id=i;   
}
    
    public Marca findbyId(String s){
        
        Integer id=Integer.parseInt(s);
        
        m=marcaDao.findById(id);
        return m;
    }   
}

Prodotto 控制器

@SessionScoped
@Named
public class ProdottoController implements Serializable {

    private static final long serialVersionUID = 1L;
    private Prodotto selected=new Prodotto();
    private Integer idTipologia;
    private Integer idCategoria;
    private Integer idSottocategoria;
    @EJB
    private ProdottoDao ejbProdotto;
    @EJB
    private TipologiaDao ejbTipologia;
    
    
    @EJB
    private SottocategoriaDao ejbSottocategoria;
    @EJB
    private CategoriaDao ejbCategoria;
    
    public Integer getIdTipologia() {
        return idTipologia;
    }



    public void setIdTipologia(Integer idTipologia) {
        this.idTipologia = idTipologia;
    }



    public Integer getIdSottocategoria() {
        return idSottocategoria;
    }



    public void setIdSottocategoria(Integer idSottocategoria) {
        this.idSottocategoria = idSottocategoria;
    }



    public Integer getIdCategoria() {
        return idCategoria;
    }
    public void setIdCategoria(Integer idCategoria) {
        this.idCategoria = idCategoria;
    }
    public List<Prodotto> listaProdotti(){
        return ejbProdotto.listAll();
    }
    
    public List<Prodotto> finbyMarca(Integer idMarca){
        
        return ejbProdotto.findByMarca(idMarca);
    }
}

它只显示第一页，当我点击另一个编号的页面时，服务器运行这个异常

好像在每次更改页面时都丢失了参数我不知道为什么，这个错误运行是否可能是因为我正在尝试使用带有 post 和 viewScoped 的 get？谢谢！

如果您使用的是 rowsPerPageTemplate="6,12,16"，那么 rows="22" 确实无效，因为 22 不是 rowsPerPageTemplate 值之一。更改任一属性以使值匹配。

查看源代码：https://github.com/primefaces/primefaces/blob/befd1b15302e46d641e4b997010c5175757c5da5/src/main/java/org/primefaces/component/api/UIPageableData.java#L290-L310

private boolean isRowsPerPageValid(String rowsParam) {

    if (rowsParam == null) {
        return true;
    }

    String rowsPerPageTemplate = getRowsPerPageTemplate();

    if (rowsPerPageTemplate != null) {
        String[] options = rowsPerPageTemplate.split("[,]+");

        for (String option : options) {
            String opt = option.trim();

            if (opt.equals(rowsParam) || (opt.startsWith("{ShowAll|") && "*".equals(rowsParam))) {
                return true;
            }
        }

        return false;
    }

    int rows = getRows();

    if (rows > 0) {
        return Integer.toString(rows).equals(rowsParam);
    }

    return true;
}
