c:set (or ui:param) and s:link, s:button action parameter

[christophea]

I'd like to use some form of aliasing for my Seam components with qualified (and yet possibly long) names. I'd like my aliases to be valid for a given page. And I'm using facelets.

I tried to use ui:param or c:set tags, and everything went fine - except with action parmaters of s:link and s:button tags.

Here's the facelet code :

<!-- my alias... -->
<!-- <ui:param name="manager" value="#{my.package.manager}"/> -->
<c:set var="manager" value="#{my.package.manager}" />

...

<s:link value="s:link" action="#{manager.start}"/> // Not working

<s:button value="s:button" action="#{manager.start}"/> // Not working

<h:form>
 <h:commandButton value="h:cmdButton" action="#{manager.start}"/> // Working fine
</h:form>

Everything works fine with h:commandButton. But for s:link and s:button I got :

javax.el.PropertyNotFoundException: Target Unreachable, identifier 'manager' resolved to null

As the action method called is #{manager.start} rather than #{my.package.manager.start}. Here is the html generated :

actionMethod=example%2Fmember_view.xhtml%3Amanager.start&cid=30

Anyone has an idea ?

Have you tried using a factory? Put this in your components.xml

 <factory name="manager" value="#{my.package.manager}"/>

No.

I just want aliasing at a particular page scope. Or I won't use qualified names for my components.

Factories in component.xml as defined in Seam reference doc is not convenient for that as far as I understood.

In a large application you may use my.package.manager bean in some pages, and another my.other.package.manager in an other. And yet want to use #{manager} in both because you know which one you want.

Ok.

Thanks and sorry. I should have had a closer look before posting.
