JSF 1.2：ui：包含参数 [英] JSF 1.2: ui:include with parameters

问题描述

按照以下规则将JSF 1.2两页（one.xhtml和other.xhtml），
包含在当前页面中：

Have JSF 1.2 two pages(one.xhtml and other.xhtml),
that are included to the current page by following rule:

...
    <c:if test="#{flowScope.Bean.param1}">
        <ui:include src="one.xhtml"/>
    </c:if> 

    <c:if test="#{!flowScope.Bean.param1}">
        <ui:include src="other.xhtml"/>
    </c:if> 
...

到目前为止 one.xhtml 与 other.xhtml 的区别仅在于操作参数：

As far one.xhtml differs from other.xhtml only by action parameters:

one.xhtml：< h：commandLink action =actionOne>

other.xhtml：< h：commandLink action =actionTwo>

one.xhtml:<h:commandLink action="actionOne">
other.xhtml:<h:commandLink action="actionTwo">

是否可以使用一些通用的xhtml？
而不是one.xhtml和other.xhtml，像这样：

Is it possible to use some general xhtml?
Instead of one.xhtml and other.xhtml,something like this:

...
    <c:if test="#{flowScope.Bean.param1}">
        <ui:include src="general.xhtml" param="actionOne"/>
    </c:if> 

    <c:if test="#{!flowScope.Bean.param1}">
        <ui:include src="general.xhtml" param="actionTwo"/>
    </c:if> 
...

谢谢你的帮助。

推荐答案

你需要在< ui中嵌套< ui：param> ：包括> 将参数传递给包含的文件。

You need to nest <ui:param> inside <ui:include> to pass parameters to the included file.

<ui:include src="general.xhtml">
    <ui:param name="action" value="actionOne" />
</ui:include>

和包含：

<h:commandButton action="#{action}" />

请注意，这仅支持字符串，而不支持操作方法。对于后者，您需要升级到JSF 2.0并使用复合组件。

Note that this only supports strings, not action methods. For the latter you would need to upgrade to JSF 2.0 and use composite components.
