Summary: entity returned by custom finder fails
Initial Comment:
I wrote a custom finder:
public Collection ejbFindByPrimaryKeys(Collection
pKeys) throws FinderException
{
Collection beans= new ArrayList(pKeys.size());
e1Home home = (e1Home)
mEntityContext.getEJBLocalHome();
for (Iterator i= pKeys.iterator(); i.hasNext
(); )
{
Integer key= (Integer)i.next();
e1 bean= home.findByPrimaryKey(key);
beans.add(bean);
}
return beans;
}
The finder works, and returns the right beans
in the collection.
As soon any getter of a bean is accessed, the
getter fails with an SQLException:

ctx.getId() returns the bean object, but is
handeled as PK object afterwards

Custom finders need to return a collection of primary key
objects. You are returning actual entity beans.
All you need to do is return the pKeys collection that is
passed in.
