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.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?
