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">
<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]}" />
