[jboss-user] [JBoss Seam] - Re: HowTo: When going to a page to enter data, pull from db

Problem


Now one problem was fixed that it picked up stuff from database. But if the row does not exist, and then when i put stuff in the form and say save/submit ... it saves blank values. nothing null

This is what my xhtml page has at the bottom. Basically it was all generated by seam-gen  (should i stop using seam-gen?) 

            <h:commandButton id="save" 
  |                           value="Save" 
  |                          action="#{activityHome.persist}"
  |                        disabled="#{!activityHome.wired}"
  |                        rendered="#{!activityHome.managed}"/>  
  |                           			  
  |             <h:commandButton id="update" 
  |                           value="Save" 
  |                          action="#{activityHome.update}"
  |                        rendered="#{activityHome.managed}"/>
  |                         			  
  |             <h:commandButton id="delete" 
  |                           value="Delete" 
  |                          action="#{activityHome.remove}"
  |                        rendered="#{activityHome.managed}"/>
  |                     
  |             <s:button id="done" 
  |                    value="Done"
  |              propagation="end"
  |                     view="/Activityxhtml"
  |                 rendered="#{activityHome.managed}"/>
  |                 
  |             <s:button id="cancel" 
  |                    value="Cancel"
  |              propagation="end"
  |                     view="/#{empty activityFrom ? 'ActivityList' : activityFrom}.xhtml"
  |                 rendered="#{!activityHome.managed}"/>


As you can see from my previous post, my values are here #{activity.entrya} Not in #{activityHome.entrya} I dont understand whats the Home stuff.

I am pretty sure that save update delete stuff is messing my app up as it points to the activityHome

help.

While we are here. THis is what i have in my action bean


  | @Out
  |     private Activity activity;
  | @Factory("activity")
  |     public void actionMethod()
  |     {
  |     	Activity activity= new Activity();
  |         try {
  |         	activity= (Activity) em.createQuery("select o from Activity o where o.userid = :num")        
  |         	.setParameter("num", 1)
  |         	.getSingleResult(); // the 1 number is temporary will change it
  |         }
  |         catch (NoResultException ex) {
  |         	FacesMessages.instance().add("Enter new activity record.");
  |         	
  |         }
  |     
  |         if(activity!= null){
  |         	setActivity(activity);
  |         }
  |         }
  | 
  | 

Scope is event and it is stateless.
