页面刷新后，JSF输入元素值导致ui崩溃

标签： jsf primefaces refresh

我有一个ui输入字段掩码的模型。该模型使用ui：repeat进行渲染。该模型是面向网格的，因此有一个SearchMaskRow类聚合了SearchMaskColumn。 SearchMaskColumn有一个成员Property，它本身的成员值类型为Object。

这里是迭代的重要部分：

<p:panelGrid id="searchMaskFieldsStaticGridId" styleClass="searchMaskFieldsGrid"
    rendered="#{not curSearch.isClosable()}">
    <ui:repeat value="#{curSearch.getSearchMaskDescription().getRows()}" var="curRow">
        <p:row styleClass="searchMaskRow">
            <ui:repeat value="#{curRow.elements}" var="curElement">
                <p:column colspan="#{curElement.columnSpan}"
                    styleClass="#{curElement.isOfDataTypeStr('label') ? 'searchMaskLabelColumn' : 'searchMaskInputColumn'}">

                    <!--  label -->
                    <h:outputLabel value="#{curElement.property.getValue()} #{curElement.colonOnRightSide ? ':' : ''}" for="colInputTextId"
                        rendered="#{curElement.isOfDataTypeStr('label')}" />

                    <!-- date data type -->
                    <p:calendar id="colCalendarId" styleClass="searchMaskInputElement" value="#{curElement.property.value}"
                        rendered="#{curElement.isOfDataTypeStr('date')}" showButtonPanel="true" showOn="button"
                        pages="#{curElement.getCalendarPages()}" size="#{curElement.getWidthInCharacters()}" />

                    <!-- string and integer data type -->
                    <p:inputText id="colInputTextId" styleClass="searchMaskInputElement" value="#{curElement.property.value}"
                        rendered="#{curElement.isOfDataTypeStr('string') or curElement.isOfDataTypeStr('integer')}"
                        size="#{curElement.getWidthInCharacters()}" />

                </p:column>
            </ui:repeat>
            <ui:param name="unfilledColumnsCount"
                value="#{searchBL.determinedUnfilledColumns(curSearch.getSearchMaskDescription(), curRow)}" />
            <p:column colspan="#{unfilledColumnsCount}" rendered="#{unfilledColumnsCount gt 0}">
                <h:outputLabel value="" />
            </p:column>
        </p:row>
    </ui:repeat>
</p:panelGrid>

首次访问ui所有作品。但是，如果通过单击浏览器刷新按钮或提交URL来刷新页面，则会出现以下异常：

提交值可能存在问题。但我调试了Property.setValue（value：Object）方法，并且设置了正确的对象。

如果我正确理解了这个异常，SearchMaskRow里面的SearchMaskElements列表（facelet中的curElement）是string类型。但我无法想象这是怎么回事。它是一个List，也没有对此列表的设置访问权限，只能在迭代时读取。 SearchMaskRow甚至还没有setter setElements（）来将字符串放入其中。 有人有想法吗？我不知道。

我正在使用： mojarra 2.1.23 主要的5.1.12 de.odysseus.juel 2.2.6

此致 奥利弗

答案 0 :(得分：-1)

你必须更改变量“value”的名称，我认为attribut'value'和你的变量之间有一个贡献。

祝你好运
