事件xforms-model-construct-done行为

问题描述

在我的表单中，我想在发布后加载表单后调用web服务。我已经为它创建了自定义的XBL控件，我有：

 < xf：group id =component-group > 
 < xf：send ev：event =xforms-enabledsubmission =my-submission/> 
< / xf：action> 
< / xf：group> 
  

但它无法按预期工作：我每次在FormBuilder中添加新元素时发送提交或更改其他控件的名称。一般来说，提交是在我的表单以某种方式更改时发送的。

现在我希望提交内容仅在我发布表单时发送，而有人会打开它填充（当然，当我在FormBuilder中按下Test时，但我想它和发布后的填充表单一样）。

我正在尝试这样的操作：

 < xf：group id =component-group> 
  < / xf：action> 
< / xf：group> 
  

不幸的是，它不起作用，这种提交方式根本没有发送。任何想法？

解决方案

这是因为XBL组件在设计时也是 live 。因此，您需要一种方法来测试组件是否在Form Builder中运行。

实际上应该有一个函数，但没有（I将其添加到我们应该添加到API 的函数列表中）。您可以这样做：


event =xforms-enabled
target =component-group
if =not（$ fr-params / app ='orbeon'和$ fr-params / form ='builder'）>
< xf：send submission =my-submission/>
< / xf：action>
< / xf：group>


一些小小的评论：

• 你不需要（事实上不应该）在嵌套操作上放置事件属性


• 你不需要甚至需要 ev 前缀

In my form I would like to call web service after to form is loaded after publishing. I've created custom XBL control for it, where I have :

<xf:group id="component-group">
    <xf:action ev:event="xforms-enabled" ev:target="component-group">
        <xf:send ev:event="xforms-enabled" submission="my-submission"/> 
    </xf:action>
</xf:group>

But it doesn't work as expected : my submission is sent everytime when I add new element in FormBuilder or change a name of some other controls. Generally speaking submission is sent when my form is changing in some way.

Now I want submission to be sent ONLY when I publish my form and someone would open it to fill (and of course when I press "Test" in FormBuilder, but I guess it's the same as filling form after publishing).

I was trying something like this :

<xf:group id="component-group">
    <xf:action ev:event="xforms-model-construct-done" ev:target="component-group">
        <xf:send ev:event="xforms-model-construct-done" submission="my-submission"/> 
    </xf:action> 
</xf:group>

Unfortunately it's not working, this way submission is not sent at all. Any thoughts ?

解决方案

This is due to the fact that XBL components are live at design time too. So you need a way to test whether the component is running within Form Builder or not.

There should be a function for this, really, but there isn't (I added this to the list of functions we should add to the API here). You can do:

<xf:group id="component-group"> <xf:var name="fr-params" value="xxf:instance('fr-parameters-instance')"/> <xf:action event="xforms-enabled" target="component-group" if="not($fr-params/app = 'orbeon' and $fr-params/form = 'builder')"> <xf:send submission="my-submission"/> </xf:action></xf:group>

A few minor comments:

• you don't need to (in fact shouldn't) place event attributes on nested actions
• you don't even need the ev prefix
