Question

I don’t knwo whether my desig itself wrong or what. but could any body give me a solution.
I have a Object, PlanningItem. From this i need to get the records form another table by using two properties of PlanningItem. so i created view and and added that view as one to many relation record in PlanningItem. when i was updating the Planning Item i am getting error.
In this i am ready to change view into and subselect or anything else. please suggest the idea to proceed.

Below is my code.

ViewPlannigItem.hbm.xml

<class

            <generator class="assigned" />
        </id>

        <property name="planningIRCDesc" column="PLANNING_ITEM_DESC"
            type="string" />


        <property name="programId" column="PROGRAM_ID" type="string" />

Answer 1

Try to set in your one-to-many side of relationship parameter inverse=”true”. This will tell hiberante not to update relationship (FK column) when you are updating parent.

I mean next:

<set name="lstViewPlanningItem"  cascade="none"  inverse="true">
         <key column="PLANNING_IRC" />
         <one-to-many not-found="ignore"
                class="com.cotyww.ipmasterdata.core.entity.master.ViewPlannigItem" />
         <filter name="planningsalesORg"
                condition="SALES_ORG_ID = :salesOrgId" />
</set>
