Inserting rows in master-detail views

Question

I have two VOs connected by a view link. I want to insert new rows in both the master VO and the detail VO and connect them together.
I have the following:
MasterEO (mapped to master_table)
MasterVO (defined on MasterEO)
DetailEO (mapped to detail_table)
DetailVO (defined on DetailEO)
MasterDetailAO (1 to many Association between MasterEO and DetailEO. master_id in detail_table references id in master_table)
MasterDetailVL (1 to many ViewLink defined on MasterDetailAO)
My AM looks like:
MasterVO
DetailVO via MasterDetailVL1
I am trying to insert a new row in MasterVO, and a new row in DetailVO that should be linked to the new row in MasterVO. I used the code listed below. I was able to get the DetailEOImpl from the new row in DetailVO, and then get the new MasterEOImpl from the DetailEOImpl. However, when I called drow.getMasterVO() (drow being the new row created in DetailVO), I got null back instead of the new row in MasterVO. What do I have to do to connect the new row in MasterVO and DetailVO? (I got the same results regardless of whether the association is a composition or not)
Also another thing I noticed, even though I've called setMaxFetchSize(0) on both VOs, the sql trace still shows the queries being executed. Is there anything else I need to do?
MasterVOImpl master = (MasterVOImpl) testAM.findViewObject("MasterVO");
DetailVOImpl detail = (DetailVOImpl) testAM.findViewObject("DetailVO");
master.setMaxFetchSize(0);
detail.setMaxFetchSize(0);
MasterVORowImpl mrow = (MasterVORowImpl) master.createRow();
mrow.setId(new oracle.jbo.domain.Number(10));
master.insertRow(mrow);
DetailVORowImpl drow = (DetailVORowImpl) detail.createRow();
drow.setDetailId(new oracle.jbo.domain.Number(100));
detail.insertRow(drow);
DetailEOImpl deoi = drow.getDetailEO();
MasterEOImpl meoi = deoi.getMasterEO();
if (meoi != null)
System.out.println("ID from EO: " + meoi.getId()); // This value is correct
Row mrw = drow.getMasterVO(); // RETURNS NULL INSTEAD OF THE NEW ROW
if (mrw != null)
System.out.println("Row Class from Detail VO: " +
mrw.getClass().getName());
else
System.out.println("Master VO is null");
// THE OTHER DIRECTION ALSO DOESN'T WORK
RowIterator rt = mrow.getDetailVO();
DetailVORowImpl dd = (DetailVORowImpl) rt.first();
// dd IS NULL
if (dd != null)
System.out.println("New Detail Row: " + dd.getDetailId());
else
System.out.println("New Detail Row from Master is null");

You need to make your ViewObjects 'AssociationConsistent' for all collections to see new rows inserted into the cache. To set this setting for all VOs, edit your Appliation Module configuration and set the value for jbo.viewlink.consistent to be true.
