为什么我的数据表的数据在我使用过滤器然后重新加载页面时没有出现？

Question

我有一个包含数据和过滤器的数据表

过滤器工作得很好，当我白色一些不存在的数据时，数据表是空的，但是当我重新加载页面时，数据确实显示在数据表中

这是我的代码

XHTML

<p:tab title="#{caseList['caseManagement.assignedToMe']}" id="myCaseTab">               
    <p:dataTable var="myCase" id="myCases"
    value="#{caseManagement.myWork}"
    widgetVar="myCaseTable"
    row="5" 
    paginator="true"
    rowsPerPageTemplate="5,10,15"
    paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
    currentPageReportTemplate="({currentPage} #{caseList['caseManagement.paginator.of']} {totalPages})"
    emptyMessage="#{caseList['caseManagement.emptyList']}"
    filteredValue="#{caseManagement.filteredMyWork}" 
    paginatorPosition="top">

豆子

private List<Case> myWork = new ArrayList<Case>(); //get and set

private List<Case> work = new ArrayList<Case>(); //get and set

private int sizefilteredMyWork;  //get and set

private int sizeFilteredAllWork;  //get and set

private List<Case> filteredMyWork;  //get and set

private List<Case> filteredAllWorks; //get and set

private Case selectedCase; //get and set

public CaseManagementBean()
{
    init();

}

public void init()
{

    addElementToMyWork();
    addElementToWork();

    setSizeFilteredAllWork(work.size());
    setSizefilteredMyWork(myWork.size());
}

我该如何解决？

public void addElementToMyWork()

    getMyWork().add(

                    null, null, null, null));

}

    getWork().add(
            new Case(null, "Double Fraud Alert Cloned Address 8892911", null, null, "-", "Collect Evidence",
                    "Manual Investigation", "Company #4", null, null, null, null));
    getWork().add(
            new Case(null, "Miami Gateway Credit Fault", null, null, "Rajesh Bonganay", "Decision Making",
                    "Manual Investigation", "Company #7", null, null, null, null));

}

Answer 1

尝试清除会话（或视图状态），然后再将其填充到过滤器的事件处理程序中。也许当你刷新 table 中的数据正在被缓存（或者在这种情况下缺少数据）。

Answer 2

解决方案是只使用一个列表进行显示和过滤

所以你必须删除

filteredValue="#{caseManagement.filteredMyWork}"

为什么我的数据表的数据在我使用过滤器然后重新加载页面时没有出现？

Why the data of my datatable doesn't apper when I use filter and then reload the page?

datatable

spring

liferay

primefaces
