propagation=drop
----------------

                 Key: JBSEAM-1221
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1221
             Project: JBoss Seam
          Issue Type: Feature Request
    Affects Versions: 1.2.1.GA
         Environment: all
            Reporter: Leo Baschy


Use is to be in

<s:link view="/myOther.xhtml" propagation="drop" value="Outta Here" />

propagation="none" is almost the same, but "none" leaves conversations stored in an inactive state until they timeout.  One might not want that, either not to use storage, or not to allow to come back, etc.

To reiterate what is specified and has been said, but still may be puzzling at times, specifically when used with s:link view="/any.xhtml", propagation="end" has effect at the end of the target page.

propagation="drop" should be like propagation="none" combined with the destruction of "end".  As a matter of symbolism, if you "drop" it then it breaks and does no longer exist.

For now one can get the effect by instead doing this (note the funny spelling of "conversaction" != "conversation"):

<s:link action="#{conversaction.endAndTo('/myOther.xhtml')}" value="Outta Here" />

backed by

import org.jboss.seam.annotations.Name;
import org.jboss.seam.core.Conversation;

@Name("conversaction")
public class Conversaction {

  public String endAndTo(String viewId) {
    Conversation.instance().end();
    return viewId;
  }
}

Would be nice to avoid the redirect.
