There's a problem with this for application servers that use pooling
with regards to entity beans. Here is what happens:
we have EntityCMP and EntityData. If you call home.findByPK(id), the
appserver will create an entity object if it doesn't have one in its
pool. then when you call getData on it, the dataHolder in the entity
will be null, and all will be well. However, the next invocation, the
appserver MIGHT decide to reuse the EntityCMP instance, and reinit its
fields. In this case, dataHolder will not be null, and you'll get old
data when you call getData.
Solution:
The check in entity-body.j 'if( dataHolder == null )' should be 'if
(dataHolder==null || !dataHolder.getPK().equals(getPK())'
where getPK is the xdoclet magic to get the entity PK.
