Customer upgraded an existing interview from 12.2.4 to 12.2.9.
They have an existing custom control and due to that they are using the August 2016 styling version. The custom control is used to select data into a hierarchy of entities. There are 5 levels in the hierarchy, and the interview will fill all information up to level 4, but when it loads the custom control for the final level I receive the following error:

If customer use the Data tab to manually add an instance of the entity, the error disappears. Using the Interview tab in 12.2.9, I have ensured that the Blank Instances is set to default to 1
