java - Redirection with method in Seam -

let's have button:

<h:commandbutton value="assign task" action="#{taskassigner.assignto(user)}"/> 

which assigns new task user. i'd able redirect task page, equivalent clicking on link like

<s:link value="#{task.description}" action="#{workontask.start}">     <f:param name="taskid" value="#{task.id}" /> </s:link> 

assuming in web-inf/pages.xml have like

<page view-id="/task-list.xhtml">     <navigation from-action="#{workontask.start}">         <redirect view-id="/task.xhtml"/>     </navigation> </page> 

i can't see how can in java in taskassigner.assignto(). need access seam component, right? need redirect /task.xhtml , set param taskid needed , run workontask.start() initialization on component.

first, not recommended use s:link-tag action-attribute (see jboss forum).

for navigation issue replace (or combine) from-action tag if-outcome 1 , return value behind if-outcome @ assignto- , workontask.start-methods.

<page view-id="/task-list.xhtml">   <navigation>     <rule if-outcome="navtotask">       <redirect view-id="/task.xhtml"/>     </rule>   </navigation> </page> 

and @ method:

public string assignto(user u) {     [...]     // in case of success     return "navtotask"; }
