VO is not getting executed or retains the previous state of execution

Question

Hi,
We have a UI for the Party Site. Under this UI, you see the address for the party. When u change the address for the party, the old party site is inactivated and a new party site would be created. Assume that all the possible set of locations already exists in the system.
Structure of the Business Components
Page is linked to PartyAM
PartySitesVO -> Linked to PartySiteEO
PartySiteVO is linked to PartyAM
Validation VO - PartySiteInCustomerAccountSiteVVO is part of AM - PartyVAM
In the PartySiteEO - When we double click, open the EO and go to Properties section, we see the below.
Properties
======
VAMDef : xxx.oracle.apps.xxad.schema.server.PartyVAM
We call partysiterow.validate() to call the validateEntity() function of the PartySiteEO which is overridden.
protected void validateEntity()
super.validateEntity();
PartyEntityExpert expert = PartySiteEOImpl.getEntityExpert(getOADBTransaction());
if (expert.isPartySiteInCustomerAccountSite(getPartySiteId().toString())
System.out.println("Throwing the exception");
else
System.out.println("Not Throwing the exception");
Package xxx.oracle.apps.xxad.schema.server;
public class PartyEntityExpert extends OAEntityExpert
public boolean isPartySiteInCustomerAccountSite(String partySiteId)
PartySiteInCustomerAccountSiteVVOImpl vvo =
(PartySiteInCustomerAccountSiteVVOImpl)
findValidationViewObject("PartySiteInCustomerAccountSiteVVO");
vvo.initQuery(partySiteId);
return vvo.hasNext();
public class PartySiteInCustomerAccountSiteVVOImpl extends OAViewObjectImpl
public void initQuery(String partySiteId)
setWhereClauseParams(null); // Always reset
setWhereClauseParam(0, partySiteId);
executeQuery();
PartySiteInCustomerAccountSiteVVO
=======================
SELECT 1
FROM hz_cust_accounts a, hz_cust_account_sites_all b
where a.cust_account_id = b.cust_account_id
AND a.status = 'A'
AND b.status = 'A'
AND b.party_site_id = :1
Using this VO we want to check, if we have an active account site linked to party site or not.
Assume we have two party site Ids 100, 200
PS - 100 is not linked to AccountSite
PS - 200 is linked to Active Account Site.
Now the problem is, we have a FOR loop where we loop through all the PartySiteIDs fetched.
When the partySiteRow.validate() is called for the first time with say PartySiteID = 100, the PartySiteInCustomerAccountSiteVVO gets executed and no rows will be fetched, so false would be returned.
When the next itteration happens and partysiteRow,validate() is called, PartySiteID = 200 is passed to PartySiteInCustomerAccountSiteVVO and still no row is returned. Ideally, I should get a row. When I run the same PartySiteInCustomerAccountSiteVVO query in toad for PartySiteUD = 200, I get 1 as the output.
I am not quite sure, if using the PartyVAM and PartyAM and something around transaction state or VO state has anything to do with the VO cache.
Please let me know, if you see any logical error into the above kind of setup. Aslo, let me know, if you have any questions in understanding this.
Thanks
Saurabh

Hi,
I am just pasting the log messages near to the VO execution. What I have done is, I have hard coded the same PartySiteID, just before calling the executeQuery in VOImpl. If you look at the log message, when the first time the VO executes, it fetches the row which is correct. But when the VO is executed again for the same or different party site id, to me it looks like, it is not at all executing the query.
In this case, since the PartySiteID is hard coded, it should return 1 row each time the executeQuery is called from VOImpl.
public void initQuery(String partySiteId)
partySiteId = "25880390";
System.out.println("party site id in initQuery : " + partySiteId);
setWhereClauseParams(null); // Always reset
setWhereClauseParam(0, partySiteId);
executeQuery();
[2254] Loading from /xxx/oracle/apps/xxad/schema/server/PartySiteInCustomerAccountSiteVVO.xml file

Please see, if you can provide me some directions or approaches which I can try.
Thanks
