Would it make sense to add:
public int getHashCode()
{
return getObjectId().hashCode();
}
To CayenneDataObject.java? The primary reason is to better support
Tapestry. In T4, the @For component can take a keyExpression (which is
parsed by OGNL) which should return the primary key, which gets placed
in the HTML page (this is used due to stale link exceptions). I don't
want to expose primary keys in the HTML, though, and using
"objectId.hashCode" doesn't work as an OGNL expression since hashCode()
!= getHashCode(). If the above method were added, "hashCode" would work
as the expression.
Any thoughts on this? Or is there another way to get a unique value for
an object that doesn't expose the entity/keys? If only Java let me get
the pointer (I miss &).
Thanks,
