XF：調度操作不會對庫組件控制

Question

[形式建設者]

確定因工作問題，所以這也成爲了兩個問題想獲得一些示例代碼工作。

我有一個表單，它有一個掛鉤在password-check事件上的Password控件上的動作，以運行一些自定義動作和提交事件，該事件被分派到該控件。表單構建器提交按鈕已配置了自定義操作，其中之一是將password-check事件分派給Password控件。這一切都有效。

由於需要創建多個表單，並對其進行相同的控制，因此我想將包含Password控件及其關聯操作和提交的部分移至部分庫。我已將該部分移至應用程序的部分庫中，並使用部分模板重建了表單。

已發佈的表單包含所需的提交和操作，但調度的事件未達到控制權（在調試日誌中，我可以看到正在運行的自定義操作和正在分派的事件，但不會（？）找到控制（見下文）：

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"} 

（相對於下文）：

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"} 

要在這個問題的一些源代碼，我創建了一個形式和圖書館只用Password控制（和測試b utton），但注意到這些操作未包含在已發佈的表單（form1）中。

所以主要問題是如果Password控件位於庫的包含部分中，如何將事件分派到Password控件？

子問題是爲什麼不包含在發佈的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."，我認爲以下示例代碼就是這種情況。

屬性 - 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>

Answer 1

您無法定位部分模板裏的控件與xf:dispatch() ，因爲部分模板中的控件使用XBL與「外部世界」「隔離」。 （考慮在一個表單中可以有多個節模板的實例，這意味着當創建節模板來引用表單中的這些控件時，不能使用您選擇的控件名稱。）

我們可以想象一下xf:dispatch()的某個版本，它可以將節目模板中的控件作爲目標，但它也需要將該節模板的名稱作爲參數。按照事實，這裏是一個可以使用的解決方法：

1. 在您的部分模板中，添加一個輸出控件，並使用CSS隱藏它。將其初始值設置爲1。
2. 而不是使用xf:dispatch()的，使用xf:setvalue()和當你在輸出領域得到xforms-value-changed，調度password-check事件由1
3. 遞增字段的值。這將起作用，因爲它是在部分模板內完成的。
