Question

我使用openfaces 3.0和wildfly 8.2.0

我在数据表

中遇到过滤器问题

当我使用过滤器正常工作

在wildfly 8.1.0中，这个问题不会发生

<o:dataTable
    var="row" 
    useAjax="true"
    value="#{docController.docs}"
    styleClass="table table-striped" pageSize="2"> 
    <o:column id="col1"
          sortingExpression="#{row.stringField1}">
        <f:facet name="header">
            <h:outputText id="id2" value="stringField1"/>
        </f:facet>
        <f:facet name="subHeader">
            <o:inputTextFilter expression="#{row.stringField1}"/>
        </f:facet>
        <h:outputText id="outputCol1" value="#{row.stringField1}"/>
    </o:column>
</o:dataTable>

它看起来像Openfaces的ajax错误。尝试删除＆＃34; useAjax＆＃34;和＆＃34;表达＆＃34;来自inputTextFilter：

<o:dataTable  var="row" value="#{docController.docs}"
styleClass="table table-striped" pageSize="2"> 
<o:column id="col1" sortingExpression="#{row.stringField1}">
    <f:facet name="header">
        <h:outputText id="id2" value="stringField1"/>
    </f:facet>
    <f:facet name="subHeader">
        <o:inputTextFilter />
    </f:facet>
    <h:outputText id="outputCol1" value="#{row.stringField1}"/>
</o:column>

引起：java.lang.IllegalStateException：TextSearchFilter应该只有一个子组件 - 搜索组件
