I see, I read through the first line of your original question too fast =)
I'm not aware of a better method that what is currently on the wiki; there had been some postings on the sun java forums in the past with regard to this, but I don't recall a concise solution. If you find one, please add to the wiki!

I want to do this User clicks Email link->do database lookup on link parameter->serve JSF view page1 or serve JSF page2 I think what you are talking about which is normal JSF: JSF view->submit link or button->do database lookup on link parameter->navigate to JSF view 1 or JSF view 2 Shawn _____ From: Romanowski, Tim [mailto:[EMAIL PROTECTED] Sent: Thursday, January 18, 2007 11:50 AM To: MyFaces Discussion Subject: RE: preprocessing static email link params before view One way is to call a method for your action, such as action=#{myBackingBean.goToResults} In your goToResults method, grab the parameter, look up what you need to in the db, then return the appropriate string corresponding to the page you want to go to. Something like this: public String goToResults(){ String param = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMa p().get("parameter_set_in_my_jsf_page"); String returnValue; // . access db, execute some logic If ( testDbCondition ){ // . returnValue = 'someString'; } else{ // . returnValue = 'someString'; } return returnValue; } If you do a web search, you'll find dozens of examples for this very question. Another way is using an actionListener, of which Tomahawk and JSF 1.2 offer different approaches. Or is your question really something more complicated than this? Tim _____ From: Garner, Shawn [mailto:[EMAIL PROTECTED] Sent: Thursday, January 18, 2007 11:14 AM To: [email protected] Subject: preprocessing static email link params before view I need the users to click on a link sent in an email to the user and go to a JSF view. However prior to serving the view I need to process a parameter in the link, look up some information the DB based on the parameter, and send them to one view or another. I see in the WIKI there is a redirect Servlet but that seems like too much work and there should be an easier way. Can somebody recommend a method to do this?
