There is a little pencil icon. This opens the dialog. Save in the dialog window closes the window and saves the changes.
One of the change they can make as I indicated is to the parent data, which is the designation which parent the child record has.
The interesting thing here is that because I am using drop-down lists, I do not have direct access to the FK value when I need it. Specifically if they change the FK value I do not have the new value. If I use value change listener the new value there just shows the integer index into an array. The way to get at the value is to let a cycle go by and catch it once it has been set with a binding for the iterator. But I don't want to (or can't) wait that long. I need that new value now!
When I change the FK value, because of the way ADF automates coordination between parent/child VO instances, the new record is quickly lost! If I look at the current record in that VO instance fairly quickly after the change has been made, this binding layer says my child/FK record no longer exists under that parent/PK. But I really need that new value.
So where is it? Where can I go look? I know it is not totally lost because the child ends up in another parent; but right when I need it I can not find it.
So where to look: in the entity cache. How do we do that?
In the VO Impl code for the child I have code that does the following:
the first line gets the entity definition for the view object. I get the definition for the first entity associated with the VO because I know the VO only has one entity associated with it. Next I get the app module (again in my app there is only one), and use that to get the particular entity I am looking for. So I use findByPrimaryKey where I plug in the EntityDef and the Key for the particular VO row I am looking for. Once I have found it I get the attribute I am interested in. ParentFKId, in this case, is the FK which points back to the master record. So now I have my new value!
