NullPointerException in updatedMessage in Home.class

[dhook.donald.hook.gmail.com]

I have a seam-gen generated application with a list page that lists out the objects, then hit the"edit" link to modify the details of the object.  When I hit save I receive a nullPointerException in the updatedMessage method, the entityClass is null when the debug statement is executied getEntityClass().getName() - see below.


Home.class
protected void updatedMessage()
   {
      debug("updated entity #0 #1", getEntityClass().getName(), getId());
      getStatusMessages().addFromResourceBundleOrDefault( INFO, getUpdatedMessageKey(), getUpdatedMessage().getExpressionString() );
   }

Not sure what I am doing as to why the entity class is not set.  This is what invokes the update in the xhtml page.

<h:commandButton id="update" value="Save" action="#{backTestHome.update}" rendered="#{backTestHome.managed}"/>

Any help would be appreciated.

Post home bean full source code and full stacktrace.

[dhook.donald.hook.gmail.com]

After further debugging, it looks like the NullPointerException is a result of getId(), because the id is null.

Here is the source & trace.

THANKS for taking a look!!!!

[dhook.donald.hook.gmail.com]

It looks like the ID is never being set.  Not sure where the setBackTestId() method is invoked within Seam.  I am assuming as part of the parameter sent from the request, but again not being invoked eventhough I have a parameter with the backTestId defined.

[dhook.donald.hook.gmail.com]

I found the problem.  In an action, a new instance of the object was being created outside of seam (new xx()).  I removed that and used the object I had injected in and it is fine.

Thanks for taking a look and your time Bernard!
