npe on simple type usage
Folks,
I keep getting NPE on simple calculations.
Is there something here that tapestry doesnt like ?
public Float getPpa() {
Float result = new Float(getPts() > 0 ? getGp() / getPts() : 0);
return result;
}
@PropertyDescriptor(nonVisual = false)
public Float getPpg() {
Float result = new Float(getPts() > 0 ? getGp() / getPts() : 0);
return result;
}
both these routines are causing NPE.
getPts() getGp() and getPts all return Integer.
?

Ken, please try to moderate your own posts better, as others have said.
Four emails in about an hour, with only you replying to your own emails, is
a real waste of everybody's attention. Until you've spent at least a few
hours on a problem, you're probably not stuck enough to beg free time from
others.

Ken,
I am glad you figured it out. But next time can you please examine the
stacktrace more carefully? Let me show you what I mean:
at org.apache.tapestry5.ioc.internal.util.ConstructorInvoker.invoke(ConstructorInvoker.java:48)
at org.apache.tapestry5.ioc.internal.util.LoggingInvokableWrapper.invoke(LoggingInvokableWrapper.java:42)
at org.apache.tapestry5.ioc.internal.OperationTrackerImpl.invoke(OperationTrackerImpl.java:74)
at org.apache.tapestry5.ioc.internal.PerThreadOperationTracker.invoke(PerThreadOperationTracker.java:87)
I agree with you that Tapestry is involved somehow (not really
surprising when writing a T5 webapp)
at org.tynamo.seedentity.hibernate.services.SeedEntityImpl.seed(SeedEntityImpl.java:133)
at org.tynamo.seedentity.hibernate.services.SeedEntityImpl.<init>(SeedEntityImpl.java:49)
Ok, Tynamo is playing in the game as well, maybe we can exclude Tapestry?
at org.hibernate.property.BasicPropertyAccessor$BasicGetter.get(BasicPropertyAccessor.java:172)
at org.hibernate.tuple.entity.AbstractEntityTuplizer.getPropertyValues(AbstractEntityTuplizer.java:482)
at org.hibernate.tuple.entity.PojoEntityTuplizer.getPropertyValues(PojoEntityTuplizer.java:241)
at org.hibernate.persister.entity.AbstractEntityPersister.getPropertyValues(AbstractEntityPersister.java:3832)
Damn it's Hibernate, for now lets ignore Tynamo, too and Tapestry is definitely not part of the game any longer...
at org.tynamo.examples.pphl.model.PlayerStats.getPts(PlayerStats.java:137)
at org.tynamo.examples.pphl.model.PlayerStats.getPpa(PlayerStats.java:125)
Now it's your code.
This is more a question to be placed at the hibernate mailing list, right? I mean honestly the starting point of your stacktrace is jetty (more or less), but you'll never even think about sending this question to the jetty mailing list, or do you?
And one more thing: We are using Tapestry for years now and honestly only a minor amount of problems were caused by Tapestry, and if than mostly due to wrong usage from our side, real bugs are rare from our experience. So please, analyze your issues carefully and think twice before sending posts to the wrong audience.
Jens

Solution...
this was a hibernate initialization issue.
I was seeding an entity
I skipped a few fields thinking it was not a problem.
but hibernate didn't like me operating on the entity while it was in its initialization phase.
rule of thumb? initialize all your properties before your code decides to operate on them.
Pheewwwwww

I use these types to get padding and comfort. It doesnt make sense to me.
Sorry to keep posting. Just trying to click and go.
What could be causing an NPE?
@Entity
@ClassDescriptor(hasCyclicRelationships = true)
@BeanModels(
{ @BeanModel(pageType = PageType.LIST,
include = "player, gp, g, a, pts, ppg",
exclude="") })
public class PlayerStats extends AbstractEntity implements Cloneable, Serializable {
public Integer getPts() {
return getA() + getG(); // offending line
}
