JSF 2.0 复合组件按钮操作无法通过 cc:attribute 设置

发布于 2024-11-26 15:40:54 字数 11330 浏览 1 评论 0原文

我想构建一个已经包含一些按钮的复合组件，并且用户可以添加其他一些按钮。

<composite:interface>
    <composite:attribute name="action" required="false" default="cancel" targets="idCancelButton" />
</composite:interface>

<composite:implementation>
    <h:panelGroup 
        layout="block"
        style="margin: 10px 0 10px 0; text-align: right;"
        styleClass="commandButtons">
        <composite:insertChildren />
        <p:spacer width="10" height="10" />
        <h:commandButton
            id="idCancelButton"
            value="Cancel"
        </h:commandButton>
    </h:panelGroup>
</composite:implementation>

对组件的调用如下所示：

<buttons:cancelButtonGroup>
    <p:commandButton id="idSaveButton" action="save" value="save" />
</buttons:cancelButtonGroup>

我在 Jetty 6 上使用 Primefaces (3.0M2) (p:commandButton) 以及 Spring Webflow 和 Mojarra 2.0.6。 正如此处所述使用操作作为目标的属性名称工作正常。唯一的问题是，可能想要在组件内使用多个预定义按钮。那么action属性就不再起作用了。我已经玩了很多，但我无法获得一个工作版本，我将属性更改为 cancelAction 并通过按钮中的 action="#{cc.attrs.action}" 引用它。请注意，由于我使用的是 Spring Webflow，取消是我的转换的名称！我不想调用返回类型为 String 的函数。我总是遇到例外：

我已经阅读了很多关于复合组件的帖子和文章，但似乎没有人将它们与 Spring Webflow 混合。或者它不值得注意，我的问题被埋在其他地方。 :)

原文

i want to build a composite component already holding some buttons with the possibility for the user to add some others.

<composite:interface>
    <composite:attribute name="action" required="false" default="cancel" targets="idCancelButton" />
</composite:interface>

<composite:implementation>
    <h:panelGroup 
        layout="block"
        style="margin: 10px 0 10px 0; text-align: right;"
        styleClass="commandButtons">
        <composite:insertChildren />
        <p:spacer width="10" height="10" />
        <h:commandButton
            id="idCancelButton"
            value="Cancel"
        </h:commandButton>
    </h:panelGroup>
</composite:implementation>

A call to the component would look like this

<buttons:cancelButtonGroup>
    <p:commandButton id="idSaveButton" action="save" value="save" />
</buttons:cancelButtonGroup>

I am using Primefaces (3.0M2) (p:commandButton) with Spring Webflow and Mojarra 2.0.6 on Jetty 6.
As already described here using action as attribute name with targets is working fine. Only problem is, that is possibly want to use more than one predefined button inside the component. Then the action attribute wont work anymore. I have been playing around a lot but I can not get a working version where I change the attribute to cancelAction and reference it via action="#{cc.attrs.action}" from the button. Note that as I am using Spring Webflow, cancel is the name of my transition! I do not want to call some function with return type String. I always get the exception:

I have been reading lots and lots of post and articles about composite component but nobody seems to be mixing them with Spring Webflow. Or it is not noteworthy and my problems is burried somewhere else. :)

看来这是一个 JSF 规范错误。

It seems this is a JSF spec error.
