Hi hibernate gurus!
I have experienced the following issue:
I have a class with some properties and 5 many-to-one relationship.
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<column name="FF_SZERZTIPUS" not-null="true" />
</many-to-one>
</class>
</hibernate-mapping>
My another class is using fszerzfej class also with many-to-one ralationship:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

<many-to-one name="tipus" class="hibernate.classes.GyujtopontTipusok" fetch="join" insert="false" update="false">

</many-to-one>
<many-to-one name="szerzodes" class="hibernate.classes.Fszerzfej" fetch="join" insert="false" update="false" >
<column name="FP_FF_ID"/>
</many-to-one>
</class>
</hibernate-mapping>
The impact is occuring when i am using fszerzpont class the fszerzfej many-to-one relationships fetching mode will be lazy=false.
I dont understand this bahaviour, i am not using getters exampl from fszerzfej.regio, fszerzfej.sterulet, fszerzfej.szerzst, fszerzfej.ufkodtipus, fszerzfej.szerztip
I am using this relations only from fszerzfej, not from fszerzpont.
I assume lazy fetching should doing this but i am surprised why not :S
How could i tell Hibernate do not use load thoose many-to-one- relations into memory?
My other question is about lazy group fetching. I have read many article but i cant achive to work properly.
Bulidtime ant instrumentation does not work for me :S
I appreciate any help!
best regards!
