How to use ui:include with parameters?

sergionni picture sergionni · Mar 13, 2011 · Viewed 53.4k times · Source

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.
