Jsf 已筛选数据表中的PropertyNotFoundException（PrimeFaces）

我有这个数据表：

<p:dataTable id="processes" var="process"
             value="#{homeBean.processesList}"
             filteredValue="#{homeBean.filteredProcesses}"
             rowKey="#{process.pid}"
             selection="#{homeBean.selectedProcesses}"
             paginator="true"
             rows="15"
             paginatorTemplate="{FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink}"
             rowsPerPageTemplate="5,10,15" >

    <f:facet name="header">
        <h:outputText value="Processes" />
    </f:facet>

    <p:column name="owner"
              filterBy="#{process.owner}"
              filterMatchMode="contains"
              sortBy="owner"
              headerText="#{homeBean.selectedLogicalServer.os eq 'Windows' ? 'User Name' : 'OWNER'}">
        <h:outputText value="#{process.owner}" />
    </p:column>

    <p:column name="pid" filterBy="#{process.pid}" filterMatchMode="exact" sortBy="pid" headerText="PID">
        <h:outputText value="#{process.pid}" />
    </p:column>

    <p:column name="ppid"
              filterBy="#{process.ppid}"
              filterMatchMode="exact"
              sortBy="ppid"
              headerText="#{homeBean.selectedLogicalServer.os eq 'Windows' ? 'Session Number' : 'PPID'}">
        <h:outputText value="#{process.ppid}" />
    </p:column>

    <p:column name="c"
              filterBy="#{process.c}"
              filterMatchMode="exact"
              sortBy="c"
              headerText="#{homeBean.selectedLogicalServer.os eq 'Windows' ? '?' : 'C'}">
        <h:outputText value="#{process.c}" />
    </p:column>

    <p:column name="stime"
              filterBy="#{process.stime}"
              filterMatchMode="contains"
              sortBy="stime" headerText="#{homeBean.selectedLogicalServer.os eq 'Windows' ? '?' : 'STIME'}">
        <h:outputText value="#{process.stime}" />
    </p:column>

    <p:column name="tty"
              filterBy="#{process.tty}"
              filterMatchMode="contains"
              sortBy="tty"
              headerText="#{homeBean.selectedLogicalServer.os eq 'Windows' ? 'Session Name' : 'TTY'}">
        <h:outputText value="#{process.tty}" />
    </p:column>

    <p:column name="time"
              filterBy="#{process.time}"
              filterMatchMode="contains"
              sortBy="time"
              headerText="#{homeBean.selectedLogicalServer.os eq 'Windows' ? 'CPU TIME' : 'TIME'}">
        <h:outputText value="#{process.time}" />
    </p:column>

    <p:column name="cmd"
              filterBy="#{process.cmd}"
              filterMatchMode="contains"
              sortBy="cmd"
              headerText="#{homeBean.selectedLogicalServer.os eq 'Windows' ? 'Image Name' : 'CMD'}">
        <h:outputText value="#{process.cmd}" />
    </p:column>
</p:dataTable>

这是类及其setter和getter中的属性

public List<LogicalServerProcess> filteredProcesses;

public List<LogicalServerProcess> getFilteredProcesses() {
    return filteredProcesses;
}

public void setFilteredUsers(List<LogicalServerProcess> filteredProcesses) {
    this.filteredProcesses = filteredProcesses;
}

公共列表筛选器进程；
公共列表GetFilteredProcess（）{
返回过滤过程；
}
公共void setFilteredUsers（列出FilteredProcess）{
this.filteredProcesses=filteredProcesses；
}

---

有什么想法吗？

问题是filteredProcesses setter被命名为

setfilteredusters

---

如果名称正确，它将正常运行

我要到两天才能运行。yi:A

确实具有属性

名称

。而是

id

。

public List<LogicalServerProcess> filteredProcesses;

public List<LogicalServerProcess> getFilteredProcesses() {
    return filteredProcesses;
}

public void setFilteredUsers(List<LogicalServerProcess> filteredProcesses) {
    this.filteredProcesses = filteredProcesses;
}
