Hi,

I am using Hibernate 3 and have run into the following situation

When I use Load...I find the record I am looking for:

NodeAlias aNodeAlias = NodeAliasDAO.getInstance().load(new Integer(anodeid));

When I run the exact same test case with find, I get an error:

NodeDateType aNodeDateType = (NodeDateType)NodeDateTypeDAO.getInstance().find("from NodeDateType NA WHERE NA.IDNode = " + anodeid).get(0);


NULL is returned in the second case.

Does anyone have an idea why this is happening?


thanks,
Minh

Remember that load() will return a proxy instead of a persisted instance. So in the first case, if aNodeAlias != NULL, it doesn't mean that the object exists. An exception will first be thrown when the proxy is later accessed, if no object was found.

use of find is not recommended since it is depricated in hibernate 3 . better go for session.createQuery()

Does the fact that you're looking up a NodeAlias in one query, and NodeDateType in the other, not have something to do with it? Different tables, etc.
