My code is completly used for quering of data, without any "save" or "update" calls.
However- I have 1 mapping that generates delete and insert statements which I can spot in the log file.
Why is it ?

I can see from the delete/insert statments that it is related with my special "set" mappings.
I.E. this set mapping :
<set name="connectedPersons" table="tRel" lazy="true" where="idevnt Is Not Null AND idpers Is Not Null" cascade="none">
<key column="idevnt"/>
<composite-element class="InfoObjectRelatedPerson">
<many-to-one name="relationType" column="reltyp" class="RelationType" insert="false" update="false"/>
<many-to-one name="targetPerson" column="idpers" class="Person" insert="false" update="false"/>
</composite-element>
</set>

will produce the SQL :
delete from tRel where idevnt=? and reltyp=? and idpers=?
insert into tRel (idevnt, reltyp, idpers) values (?, ?, ?)

And I do not know why this SQL is generated.
Can you please help ?

Thank you !

P.S. - this is the full mapping file, in case it is needed :

The mapping is :
