parametized page definitions 
-----------------------------

                 Key: JBSEAM-2365
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2365
             Project: JBoss Seam
          Issue Type: Feature Request
    Affects Versions: 2.0.0.GA
            Reporter: koen handekyn
            Priority: Minor


for typical administration pages one typicalle has a ' list + search '  with corresponding details page.

for each of the details pages of all of the editable entities i'm repeating the below

  <page
    view-id="/up/admin/portalConfiguration.xhtml"
    conversation="portalConfigurationConversation"
  >
    <begin-conversation nested="true" />
    <navigation from-action="#{backingBean['persist']">
      <end-conversation />
      <redirect view-id="/up/admin/portalConfigurationList.xhtml" />
    </navigation>
    <navigation from-action="#{backingBean['update']}">
      <end-conversation />
      <redirect view-id="/up/admin/portalConfigurationList.xhtml" />
    </navigation>
    <navigation from-action="#{backingBean['remove']">
      <end-conversation />
      <redirect view-id="/up/admin/portalConfigurationList.xhtml" />
    </navigation>
  </page>

as GK started of seam with DRY in mind, this repetion should be avoidable.

i propose a solution like the following

  <page
    view-id="/up/admin/*.xhtml"
    conversation="%{page}Conversation"
  >
    <begin-conversation nested="true" />
    <navigation from-action="#{backingBean['persist']">
      <end-conversation />
      <redirect view-id="/up/admin/%{page}List.xhtml" />
    </navigation>
    <navigation from-action="#{backingBean['update']}">
      <end-conversation />
      <redirect view-id="/up/admin/%{page}List.xhtml" />
    </navigation>
    <navigation from-action="#{backingBean['remove']">
      <end-conversation />
      <redirect view-id="/up/admin/%{page}List.xhtml" />
    </navigation>
  </page>

i.e.

when a page matches   " view-id="/up/admin/*.xhtml" " the * is matched and assigned to a variable " page " that can be used below.
