Issue with changing an array rule input

Can you provide some clarification on a few points?

• What did you change about the rule input? 
  • Specifically, what was it set to before and what is it set to now?
• What worked differently prior to this change?
• What are you expecting to have happen?  What are you seeing instead?
• Additionally, if you can share the code for your interface (please use 'Insert' --> 'Insert Code' functionality), that would help us troubleshoot any apparent issues.

I created the form as a template from a data type, but I had to delete the data type as I struggled with updating the Appian cloud DB table. Anyhow:

1. I deleted the rule input which was automatically generated via the template and added a new one using the little plus sign. Before it was something like similar to the following:

Afterwards I do not see this sub-entries any more.

2. I do not understand your question. But the underlying motivation for changing the rule input was that I changed the datatype to account for data base model changes, since the DB did not update automatically (it is has to do with capital letters and underliners I am using, but I fixed that with the XSD-download-upload-trick)

3. I hope (1) clarifies that.

4. The code of the interface is the following:

What is the data type of ri!person?  From your initial screenshot it looks as if it's set to be an array, which it shouldn't be.  And also it would be nice if we can confirm that it's set as a CDT with the proper fields, in accordance to how your on-form saves are configured.

It was a CDT and it was supposed to be one after re-inserting a new variable. I played with an array, so that's the confusing screen-shot came about. Sorry for that.
