When attempting to select an option from a drop-down list during runtime on a user interface within a parent model (Model A) that has a page include region of Model B's UI (The referenced child) within an Instance List Layout region, the following error occurs.

STEPS
-----------------------

The following steps can be used to create models and UI that reproduce this behavior:

1. Configurator Developer responsibility

2. Create two models, using “Parent Model” and “Child Model” for example purposes

3. Edit “Child Model”, navigate to structure and create a component

4. Set the new component as follows, with Multiple or Variable instance with minimum 1 and maximum N

5. Finish, and create a new UI for “Child Model”. Used “Step-By-Step Navigation”, but create an empty UI.

6. On Page-1 of the new UI, create a custom button. Set the associated node as the recently created “Child Component”, action defined as “Add Instance”.

7. Add a Instance List Layout Region – Table. Set associated model node as “Child Component”.

8. Create a Styled Text for the Component Row of the instance list created in step 6.

9. Navigate back to “Parent Model” and create a Model Reference to the “Child Model” in the structure tab. No additional options were set. Parent model structure at this point:

10. Create a new UI for “Parent Model”. Used the same setup as step 4, step-by-step but creating blank UI.

11. In the newly created UI, create one page include region on page 1 referencing the Child Model.

12. The Parent Model UI should now look like the following:

13. Generate logic on child and parent. Then, select “Test Model” on the Parent Model.

14. Error occurs
