Hi BoxCoder,
This community project was originally written against 9.3, and hasn't been upgraded since then. In 11.0, this project has been mostly replaced by the Impact Matrix which exists OOTB on the Express ECO ItemType. The Impact Matrix serves a similar purpose in terms of informing the user about other related items that might be affected by the current change.
If you're looking to have something like this wizard on the ECR, I'd recommend instead taking a look at the ECR Impact Matrix community project which gives an example of how to add the standard Impact Matrix to the ECR ItemType.
