Due to some custom components which expect a bean name (NOT the bean instance) in their attributes I need to pass the actual bean name between pages. As the bean itself is also used by non-custom components, I would like to avoid using additional ui:param
(like described here Passing action in <rich:modalPanel>) since it will essentially specify the same bean.
Is it possible to specify component's action using bean name provided with ui:param
?
Basically I am trying to achieve the following:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
template="/template.xhtml">
<ui:param name="beanName" value="sessionBean"/>
...
</ui:composition>
and template.xhtml is
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:a4j="http://richfaces.org/a4j"
template="/someothertemplate.xhtml">
</ui:define name="somename">
<h:form>
<a4j:commandButton value="test" action="#{beanName.delete}"/>
</h:form>
</ui:define>
</ui:composition>
Although delete method is properly defined (verified with action="#{sessionBean.delete}"
) the above code gives me
javax.faces.FacesException: #{beanName.delete}: javax.el.MethodNotFoundException: /template.xhtml @201,89 action="#{beanName.delete}": Method not found: sessionBean.delete()
You should be able to reference the bean via its scope:
<a4j:commandButton value="test"
action="#{sessionScope[beanName].delete}"/>
