Url rewrite and different actions to execute for different patterns.

[vestnik]

I have one template which can be used for viewing, editing and creation of entities. In any use case it requires execution of some actions before rendering which loads some necessary data and those actions are different for view/edit mode and creation mode. With any use case URL should be restful.

To satisfy those requirements I've created some funny but working kludge. I've created two additional files: create.xhtml and create.page.xml with the following content:

<ui:include xmlns:ui="http://java.sun.com/jsf/facelets" src="view.xhtml"/>

<?xml version="1.0" encoding="UTF-8"?>
<page view-id="/courses/classes/create.xhtml">
   <action execute="#{classesViewer.initCreation}"/>
</page>

Right now I have some time for refactoring of this part of application and I want to do it in better way. Is it possible to have different actions for different patterns of the same view? Something like:

<?xml version="1.0" encoding="UTF-8"?>
<page view-id="/courses/classes/view.xhtml">
   <rewrite pattern="/courses/classes/view/{id}">
      <action execute="#{classesViewer.initView}"/>
   </rewrite>
   
   <rewrite pattern="/courses/classes/create">
      <action execute="#{classesViewer.initCreation}"/>
   </rewrite>
</page>

Are there any way to do that or similair things with SEAM? Is it possible to reuse facelet file for several different URLs with different component initialization without kludges?

Well I would like to know that too...
Because even if you specify an view-id twice in the pages.xml it will not work (yeah okay it's the ID I know but there should be a was...)
And even using an empty .xhtml in combination with a render statement feels kind of hacked...
