NPE With Simple Persist

[nathandennis]

Jboss 4.2.2 seam 2.0.1.ga richfaces 3.1.4.ga
i had preformed something simular successfully in seam 1.2.1. ive stared at this for 4 days,, with no luck. hopefully someone can point to where im conceptually wrong.

@Stateful
@Name("timelineAction")
@Scope(ScopeType.CONVERSATION)
public class TimelineAction implements TimelineLocal, DropListener {
     
     @PersistenceContext
     private EntityManager entityManager;
     
     @In(required = false) @Out(required=false)
        private Events newevent; 

public void processDrop(DropEvent dropEvent) {
          ....
          moveFramework(dropEvent.getDragValue(), dropzone.getDropValue());
          } else{
               log.info("drag value is null");
          }
     }

     @SuppressWarnings("unchecked")
     public void moveFramework(Object picturelist, Object zone) {
          log.info("top of moveFramework()");
          ArrayList<Events> target = null;
          ArrayList<Thumbnails> thumbframe = thumblist;

          //target = (ArrayList<Event>) eventlist.getResultList();
          //if (target != null) {
          
     //seperate the dropzone name so we know which month and year to to get
          String token = "_";
          StringTokenizer is = new StringTokenizer(zone.toString(), token, false);
     //save the month and year
          int year = Integer.valueOf( is.nextToken(token) ).intValue();          
          int month = Integer.valueOf( is.nextToken(token) ).intValue();
     //query the db to see how many events are in the selected month
          
          ArrayList<String> restrictions = new ArrayList<String>();     
          restrictions.add("eventuserid= '"+identity.getUsername() + "'");
          restrictions.add("eventyear=" + year);
          restrictions.add("month="+month);
          EventsList eventcountmonth = new EventsList();
               eventcountmonth.setRestrictions(restrictions);
     //test to see if their are less than 9 events in the month
               
          
               List<Events> eventcountlist = eventcountmonth.getResultList();
     
          if (eventcountlist.size()<= 9) {
                    
               int ind = thumbframe.indexOf(picturelist);
               //set the active thumbnail image for refercing in the jsf
               activethumb = thumbframe.get(ind);
               
               if (ind > -1) { 
                    
                    newevent = new Events();
                    
                    log.info("past new object");
                    newevent.setEventuserid(identity.getUsername());
                    newevent.setEventtimelineid(tlid);
                    newevent.setEventname("Event: " + Integer.toString((eventcountlist.size() + 1)));


......... sets more values...... doesnt persist yet


     public void saveEvent(){
///388 breaks here
          newevent.setEventname("somename");
             newevent.setEventdescript("this.eventdescript");
          entityManager.persist(newevent);
          
          }

the process is started from a drag drop event. it instantiates the entity Events events and set parameters. All executes good.

some JSF sippets

 <rich:dropSupport dropValue="#{yearvar.year}_#{yearvar.month}"
                    dropListener="#{timelineAction.processDrop}" 
                    acceptedTypes="pic"
                    reRender="eventcontainer"
                    oncomplete="Richfaces.showModalPanel('eventmp');">

.......



<rich:modalPanel  id="eventmp" minHeight="500" 
                              minWidth="450" top="20" style="padding:0px;"
                              onhide="rerenderImageTable();">
           
        <div style="position:absolute;top:25px;left:25px;">

             alt="Imagefileupload" style="z-index:250;"
             rendered="#{not empty activethumb}" />     
  
  <h:form>
<s:decorate id="eventnameDecoration" template="../layout/edit.xhtml">
          <ui:define name="label">Event Name:</ui:define>
           <h:inputText value="#{timelineAction.eventname}" 
                             style="padding:2px;padding-left:4px;" required="true"/>
     </s:decorate>
     <s:decorate id="eventdescriptDecoration" template="../layout/edit.xhtml">
                <ui:define name="label">Event Details</ui:define>
                <h:inputTextarea id="eventdescript"
                               cols="80"
                               rows="3"
                              value="#{timelineAction.eventdescript}"/>
    </s:decorate>
          <a:commandButton style="top:200px;" actionListener="#{timelineAction.saveEvent}" value="Save Event"/>     
     </h:form>

no matter how i arrange this.. i get a NPE when the saveEvent is called. as you can see at this point i really wasnt even testing the form.. just passing String values to the entity object in the session bean.

when i use debug,, i see the newpic object sitting out there with all my data in it...

Whats happening to me here??

could this possibly have something to do with these richfaces functions? calling from the mod panel or something.. i know you could do instantiate in one method and persist in another while in Conversation context in seam 1.2.1. the working example of this has been deployed for almost a year now.

IS THERE A WORKAROUND I CAN TRY?

[nickarls]

Show the full stack trace. Is it the entitymanager that is not injected?

[nathandennis]

thanks for the response...
unfortunately it is,,, im already using several other places in the class.

Is event or events a key word.. possibly getting on top of something?

Which line exactly is 388?

[nathandennis]

it is marked in the above code.. but i got it off by one line

387 public void saveEvent(){
388           newevent.setEventname("somename");
389             newevent.setEventdescript("this.eventdescript");
390          entityManager.persist(newevent);
          
          }

it is not going back to the previously instantiated object for some reason.
there is only one copy of timeline Action and obviously one copy of newevent. but it is as if it is looking for another one that doesnt exist.

[nathandennis]

4 days later i have solved this one.

it is the combination of richfaces ajax calls... possibly from using

   <h:panelGroup id="eventwizard">
        <a:include  viewId="include/event.xhtml" />
   </h:panelGroup>

modal panel

to include the modalPanel in the main xhtml.
the problem is exactly what i said in the above post.. it is looking for a bean that doesnt exist in the ajax submit. because the pageation never change, it isnt readily visible,, because the session id doesnt change on the main page. when the session id isnt specified,, it looks like it just gets a new one.  which is a big problem considering  i wanted data from the previous session.. the question is why is it losing it? i have a feeling i should be in the richfaces form to ask this question... but since i lost 4 days,, messing with it.. im going to wait until im not as press to fully understand the problem i just encountered. (this way i get the joy of experiencing it more than once.... sarcasm)

very simple to fix once we get our brain around it...

          <a:commandButton style="top:200px;" actionListener="#{timelineAction.saveEvent}" value="Save Event">
               <s:conversationId/>
          </a:commandButton>     

and the problem magically goes to /dev/null

thanks for the help. it encourage me to think.
