HibernateEntityValueEncoder NPE
Hi All!
I detected a bug(?) in the HibernateEntityValueEncoder. When the
hibernate entity's primary key contains an underscore in the primary key
member name like
private Long _pk;
than the HibernateValueEncoder fails with:
Caused by: java.lang.NullPointerException
at
org.apache.tapestry5.internal.hibernate.HibernateEntityValueEncoder.toClient(HibernateEntityValueEncoder.java:59)
at org.apache.tapestry5.corelib.components.Loop.begin(Loop.java:396)
at org.apache.tapestry5.corelib.components.Loop.beginRender(Loop.java)

at
org.apache.tapestry5.internal.structure.ComponentPageElementImpl$AbstractPhase.invoke(ComponentPageElementImpl.java:143)
because the "propertyAdapter.get" method returns "null" for the given
entity instance. The root cause for this is here
(HibernateValueEncoder:51):
propertyAdapter =
propertyAccess.getAdapter(this.entityClass).getPropertyAdapter(property.getName());
as property.getName returns "_pk" which is not in the list of adapters,
but "pk" is...
The easy work around is just to rename all my _pk fields, but as
Tapestry is happy with "leading underscores" the hibernate integration
should be too?
Is there something wrong on my side or shall I fill a jira?
Jens
