ADF Toplink Create Row with foreign key

Question

Hello,
I'd like to create a new row in a table that has a required one-to-one mapping relationship (foreign key). I've created an edit form by dragging the return node of a readQuery. The columns holding foreign key values aren't added to the page(because of 1-1 relationship) and when I commit the changes errors are raised.
How do I pass the foreign key to the ADF Toplink framwork to include in the insert statement.

TopLink's persistence model is based around relationships, which represent FKs. To have these FKs properly populated you need to create the corresponding object relationships.
To do this you need to create a data action that will invoke a method on your class passing in the object you want to create the relationship with. There is currently an issue where ADF will not allow you to easily drop a set method onto an action. You will need to create a method on your bean that does not start with 'set'.
In the demos I have done I have added a method like 'populateAddress(Address)' that internally calls the set method. This populate method will show up on the data control palette and you can then drop it on the action in your page flow.
One additional tip: To access the object you want to pass in you will need to extend the default expression that reflects the current selected row in the iterator to have '.dataProvider' appended. This accesses the persistent object within row container.
