I'm getting this with both 1.1 and what's currently in CVS. I'm getting
an NPE at
cirrus.hibernate.helpers.ReflectHelper.get(ReflectHelper.java:169)
because target is null.
My mapping looks like this:
<class name="Foo" table="Foos">
<id name="id" column="id" type="string" unsaved-value="null">
<generator class="assigned" />
</id>
<property name="name" />
<component name="subComp" class="SubComp">
<property name="version" column=version" />
<property name="value" column="value" />
</component>
</class>
All I'm doing is:
Foo f = new Foo();
f.setId("ID1");
session.save(f);
If I comment out the <component> element, everything works.
Any ideas?
-Mark

Curious.
I managed to reproduce an NPE just like this, but from update(), not
save()......
Are you sure it originated in save() .... can you show me a stack trace
please.
I'm concerned that the testsuite didn't show this / these problems :(

Yes, I'm doing a save(). Stack trace:

Yeah, that confused me too, since I checked the test suite and saw that
there were tests for this, and thought it was something I was doing....

Huh???? What on earth is being cascaded here? You have no associations in
the mapping you showed me!
If cascade() is getting called for a mapping with no associations, theres
something very wrong, so please send me a copy of the code that reproduces
this.....

A set of strings isn't an association... So I'm still confused why cascade() is called. ----- Original Message ----- From: "Mark Woon" <mor...@SM...> To: "Gavin King" <ga...@ap...> Sent: Wednesday, September 25, 2002 10:56 PM Subject: Re: [Hibernate] Problem with <component> element > Gavin King wrote: > > >>>cirrus.hibernate.impl.SessionImpl.saveOrUpdate(SessionImpl.java:897) > >>> > >>> > > at cirrus.hibernate.impl.Cascades$2.cascade(Cascades.java:37) > > at cirrus.hibernate.impl.Cascades.cascade(Cascades.java:130) > > at cirrus.hibernate.impl.SessionImpl.cascade(SessionImpl.java:1770) > > at cirrus.hibernate.impl.SessionImpl.doSave(SessionImpl.java:576) > > at cirrus.hibernate.impl.SessionImpl.save(SessionImpl.java:458)<< > > > >Huh????
