Orbeon Runner - 计算值

Question

我制作了一个带有一些文本输出控件的表单，这些控件具有由其他一些具有计算值的控件计算的值。问题是，在测试模式下（来自构建器），这些控件正常工作。在 runner 中，这些控件始终为 0（空）。保存文档并再次打开后，值正确，但不刷新。

这是我的实例：

<xforms:instance id="fr-form-instance">
    <form>
        <section-1>
            <first>
                <first_amount/>
                <first_percent/>
                <first_total/>
            </first>
            <second>
                <second_amount/>
                <second_percent/>
                <second_total/>
            </second>
            <third>
                <third_amount/>
                <third_percent/>
                <third_total/>
            </third>
            <total/>
            <average/>
        </section-1>
    </form>
</xforms:instance>

还有我的绑定：

<xforms:bind xmlns:dataModel="java:org.orbeon.oxf.fb.DataModel" id="fr-form-binds"
             nodeset="instance('fr-form-instance')">
    <xforms:bind id="section-1-bind" name="section-1" ref="section-1">
        <xf:bind name="first" id="first-bind" ref="first">
            <xf:bind name="first_amount" id="first_amount-bind" ref="first_amount"
                     type="xf:decimal"/>
            <xf:bind xmlns:fb="http://orbeon.org/oxf/xml/form-builder" name="first_percent"
                     id="first_percent-bind"
                     ref="first_percent"
                     type="xf:decimal"
                     constraint="./text()&gt;=0 or string-length(./text())=0"/>
            <xf:bind xmlns:fb="http://orbeon.org/oxf/xml/form-builder" name="first_total"

                     ref="first_total"
                     calculate="(../first_amount/text() * ../first_percent/text()) div 100"
                     type="xf:decimal"/>
        </xf:bind>
        <xf:bind name="second" id="second-bind" ref="second">

                     ref="second_total"
                     calculate="(../second_amount/text() * ../second_percent/text()) div 100"
                     type="xf:decimal"/>
        </xf:bind>

                     ref="third_total"
                     calculate="(../third_amount/text() * ../third_percent/text()) div 100"
                     type="xf:decimal"/>

Answer 1

这似乎适用于我提供的表单，无论是在测试模式下还是在部署表单时（参见屏幕截图）。我正在使用 Orbeon Forms 4.1。

没关系，但这里有几个关于 XPath 表达式的 cmets：

• XPath 中几乎不需要text()，您可以删除表达式中所有出现的/text()
• 您可以使用ge 运算符代替>=，这样更易​​读
