Dear all,

I would like to ask two questions.
1. if i have defined a mappping with contains a set of components which are stored in another table, if i want to do a update on those component, how should i write the hsql.
e.g.
<hibernate-mapping package="pk.mapping">
<class name="A" table="TABLE_A">
.........
<set name="B" table="TABLE_B" lazy="false" fetch="join">
<key>
<column name="K1"/>
<column name="K2"/>
<column name="K3"/>
</key>
<composite-element class="Com1">
<property name="f1" type="date" column="F1" />
<property name="f2" type="string" column="F2" />
</composite-element>
</set>
........
</class>
</hibernate-mapping>
and i used query.createQuery("update A set B.f1=xx where K1=yy")
and it is translated into "update TABLE_A set F1=xx where K1=yy" by hibernate, but since F1 is in table B, so there is error. Have i set any wrong?

2. If i have a set collection mapped in another table, if originally there is 3 elements in a set and i deleted 1 element, will hibernate automatically delete the removed element from the table?

Thank you!
