saveOrUpdate always updates

[Gayatri Ganesh]

Hi,

I need to save or update an object to the database.
I use the seeion.saveOrUpdate(myobj) method but it always updates the object even the 1st time when the object is created. And hence the object is never stored to the db.


The hbm file is as follows :

<class name="MyClass" table="Mytable" lazy="true" dynamic-update="true" dynamic-insert="true">
<meta attribute="extends">MySuperClass</meta>
<cache usage=nonstrict-read-write"/>
<composite-id class="MyPK" name=Id">
<key-many-to-one column="mycolumn1" name="myColumn1" class="MyColumn1"/>
<key-many-to-one column="mycolumn2" name="myColumn2" class="MyColumn2"/>
</composite-id>
....

can anyone please tell me what is wrong ?

thanks
Gayatri

from hibernate docs:

You may instead implement Interceptor.isUnsaved() if you wish to use saveOrUpdate() or cascading save / update. As an alternative, you may also set the unsaved-value attribute on a <version> (or <timestamp> element to specify a value that indicates a new transient instance. In this case, the version of the entity is used instead of the (assigned) identifier and you don't have to implement Interceptor.isUnsaved() yourself.
