lazy="true" in hibernate mapping

Hi Martin,

an another question today:

If I set lazy = "true" in the mappingfile, I get the NullPointException:

at 
org.hibernate.tuple.AbstractEntityTuplizer.createProxy(AbstractEntityTuplizer.java:372)

If I set the lazy ="false", in case if there are much data from a query, the 
Exception:
     ORA-01000: Maximale Anzahl offener Cursor überschritten

Reason: all the associated objects are loaded,  thounds selects are called.

How can I stop to load the assoicated objects by a query?

Thanks for your help and have a nice weekend!
