XF：调度操作不会对库组件控制

Question

[形式建设者]

确定因工作问题，所以这也成为了两个问题想获得一些示例代码工作。

我有一个表单，它有一个挂钩在password-check事件上的Password控件上的动作，以运行一些自定义动作和提交事件，该事件被分派到该控件。表单构建器提交按钮已配置了自定义操作，其中之一是将password-check事件分派给Password控件。这一切都有效。

由于需要创建多个表单，并对其进行相同的控制，因此我想将包含Password控件及其关联操作和提交的部分移至部分库。我已将该部分移至应用程序的部分库中，并使用部分模板重建了表单。

已发布的表单包含所需的提交和操作，但调度的事件未达到控制权（在调试日志中，我可以看到正在运行的自定义操作和正在分派的事件，但不会（？）找到控制（见下文）：

2016-03-15 12:07:10,439 DEBUG XFormsServer - process: combining with then {action: "ActionNode(xf:dispatch,Map(Some(name) -> password-check, Some(targetid) -> Password-control))"} 
2016-03-15 12:07:10,439 DEBUG XFormsServer - start process: running action {action: "ActionNode(xf:dispatch,Map(Some(name) -> password-check, Some(targetid) -> Password-control))"} 
2016-03-15 12:07:10,439 DEBUG XFormsServer - end process: running action {time (ms): "0", result: "success"} 

（相对于下文）：

2016-03-15 12:09:26,385 DEBUG XFormsServer - start process: running action {action: "ActionNode(xf:dispatch,Map(Some(name) -> password-check, Some(targetid) -> Password-control))"} 
2016-03-15 12:09:26,386 DEBUG XFormsServer -   start dispatching {name: "password-check", target: "SignOff-control≡xf-637≡Password-control"} 
2016-03-15 12:09:26,386 DEBUG XFormsServer -    start handler {name: "password-check", phase: "target", observer: "SignOff-control≡xf-637≡Password-control"} 
2016-03-15 12:09:26,386 DEBUG XFormsServer -    interpreter - start executing {action name: "xf:action"} 
2016-03-15 12:09:26,386 DEBUG XFormsServer -     interpreter - start executing {action name: "xxf:script"} 

要在这个问题的一些源代码，我创建了一个形式和图书馆只用Password控制（和测试b utton），但注意到这些操作未包含在已发布的表单（form1）中。

所以主要问题是如果Password控件位于库的包含部分中，如何将事件分派到Password控件？

子问题是为什么不包含在发布的form1版本中的操作？我看到"Actions involving controls in a given section are automatically included with the section template, along with the services called by the actions."，我认为以下示例代码就是这种情况。

属性 - local.xml中

<property as="xs:string" name="oxf.fr.detail.buttons.TEST.*"> 
    cancel 
    submit 
</property> 

<property as="xs:string" name="oxf.fr.detail.process.submit.TEST.*"> 
    xf:dispatch(name = "password-validate", targetid = "field-control") 
    then require-valid 
    then xf:send("StoreDocument-submission") 
</property> 

TEST /库

Answer 1

您无法定位部分模板里的控件与xf:dispatch() ，因为部分模板中的控件使用XBL与“外部世界”“隔离”。 （考虑在一个表单中可以有多个节模板的实例，这意味着当创建节模板来引用表单中的这些控件时，不能使用您选择的控件名称。）

我们可以想象一下xf:dispatch()的某个版本，它可以将节目模板中的控件作为目标，但它也需要将该节模板的名称作为参数。按照事实，这里是一个可以使用的解决方法：

1. 在您的部分模板中，添加一个输出控件，并使用CSS隐藏它。将其初始值设置为1。
2. 而不是使用xf:dispatch()的，使用xf:setvalue()和当你在输出领域得到xforms-value-changed，调度password-check事件由1
3. 递增字段的值。这将起作用，因为它是在部分模板内完成的。
