ui:param value accessible in backing bean?
Is it possible to access the value of a facelets ui:param tag in phase
render response in a backing bean?
I tried to resolve #{activeTab} in MyController.getOnlick() without success.
Sample:
1) Template
<ui:composition template="templates/main.xhtml">
<ui:param name="activeTab" value="blabla"/>
<ui:define name="navigation">
<ui:include src="/facelets/navigation.xhtml"></ui:include>
</ui:define>
2) navigation.xhtml
...
<t:commandLink onclick="#{MyController.onlick}"
...
I use myFaces 1.2.9 and facelets 1.1.15.
Thanks,
Michael

Just FYI: I changed the location of the custom-tags project to

Hi Michael,
I just created a Facelets 1.1.x custom tags project and adapted the
SetHandler from MyFaces core 2.0 for Facelets 1.1.x.
You can find the source at
http://jakobk-extensions.googlecode.com/svn/trunk/jsf/facelets1/facelets1-custom-tags/
Just check it out and use mvn clean install to get the JAR. If you include
this JAR in your webapp, you can use the custom set tag like this:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:jk="http://facelets.jakobk.at/customtags">
<jk:set target="#{requestScope}" property="foo" value="fooValue" />
I hope you can use this solution.

Jakob

Hi Michael,
"I migrated my app from jsp/tiles to xhtml/facelets successfully in the last
2-3 days."
That's great :)
Hm, yes. Unfortunately I digged deeper into it and found out that <c:set> is
equal to <ui:param> on facelets-1.x, thus the suggested code only works for
JSF 2.0. I am sorry, but this means that you will have to find some other
tag which accomplishes this or you will have to write your own one (which
should not be too hard, because you can take the code from MyFaces core 2.0
SetHandler --> org.apache.myfaces.view.facelets.tag.jstl.core.SetHandler and
just register it in your facelets taglib).
I hope this helps!

Jakob

Re: ui:param value accessible in backing bean?
Posted by Michael Heinen <mh...@googlemail.com>.
Hi Jakob,
I migrated my app from jsp/tiles to xhtml/facelets successfully in the
last 2-3 days.
But your hint is unfortunately not working for me.
namespace in xhtml file for core tags is:
xmlns:c="http://java.sun.com/jsp/jstl/core"
Is this the right one or do I have to use
xmlns:c="http://java.sun.com/jstl/core" (without jsp)?
jstl-1.2.jar is in the lib folder of my webApp.
<c:out does not print anything and the set value is also not accessible
via EL in the getter of my bean.
My current code:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:c="http://java.sun.com/jsp/jstl/core">
<ui:composition template="templates/main.xhtml">
<ui:param name="activeTab" value="wb"/>
<c:set var="foo2" value="bla2" scope="request"/>
<c:set target="#{requestScope}" property="foo" value="fooValue" />
<ui:define name="navigation">
<ui:include src="/facelets/parts/navigation.xhtml"></ui:include>
</ui:define>
I try to access foo and foo2 in navigation.xhtml and in a getter called
from navigation.xhtml.
Any Idea what's going wrong here ?
Greetz,
Michael

Re: ui:param value accessible in backing bean?
Posted by Jakob Korherr <ja...@gmail.com>.
Hi Michael,
You can use <c:set> from the JSTL to put the value into the request scope.
Then you can access it in the facelet and also later in the action method.
Namespace: xmlns:c="http://java.sun.com/jsp/jstl/core"
<c:set target="#{requestScope}" property="foo" value="fooValue" />
Regards,
Jakob

Hi
I checked in deep some days ago ui:param, and it only define the expression
when the view is build, but its context is not preserved on other phases.
FaceletContext extends from ELContext and override its VariableMapper and
FunctionMapper. So in practice, ui:param just add a variable on the variable
mapper. but after ui:composition and ui:include ends its processing the
variable is just discarded, because the whole VariableMapper wrapper created
by this two tags is removed too.
