How to use ui:include with parameters?

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> 
...

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

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

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

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>

thank you for help.


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>

and in the include:

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

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.


In addition to BalusC's answer:

There is a way to do this with JSF 1.2, though it's somewhat ugly:

<ui:include src="general.xhtml">
    <ui:param name="actionBean" value="#{myBackingBean}" />
    <ui:param name="actionMethod" value="edit" />
</ui:include>

and

<h:commandButton action="#{actionBean[actionMethod]}" />
