Sharing new EO instances

Question

I want to find out how I can display in a VO a new EO instance that was created from another VO using the createRow method.
Let's say I have:
OrderHeaderEO - based on order_headers table
OrderSummaryVO - Summary view of OrderHeaderEO
OrderDetailsVO - Detailed view of OrderHeaderEO
I have the the following:
-- this creates a new EO instance as part of row creation
OrderSummaryVORowImpl rw = (OrderSummaryVORowImpl) myOrderSummaryVO.createRow();
rw.setAttribute(...);
myOrderSummaryVO.insertRow(rw);
Now I want to show this new EO instance in OrderDetailsVO. Since this is not yet saved in the database, I cannot query. How can I create a new row in OrderDetailsVO but have the underlying EO instance point to an existing EO instance?
Will something like this work:
-- rw was the row created above
OrderHeaderEO eo = rw.getOrderHeaderEO();
OrderDetailsVORowImpl rw2 = (OrderDetailsVORowImpl) myOrderDetailVO.createAndInitRow(eo);
Then in the create(AttributeList nvp) method of OrderDetailsVORowImpl, I do the following:
this.setEntity(0, (OrderHeaderEO) nvp);
Would this work or are there better ways?

Answer 1

OrderSummaryVORowImpl rw = (OrderSummaryVORowImpl) myOrderSummaryVO.createRow();
rw.setAttribute(...);
myOrderSummaryVO.insertRow(rw);Right after inserting the row in OrderSummaryVO as above, call
myOrderDetailsVO.insertRow(rw);
After that, myOrderSummaryVO will have a View Row that uses the new EO and myOrderDetailsVO will also have a View Row that uses the same new EO instance. I.e., two View Rows (one in Summary and one in Details), but they both point to the same EO instance.
Thanks.
