Hi! Following your examples and documentation, I am able to generate report with dynamic column but the renders duplicate rows.

I have tested the query and the result is correct. No duplicate rows. I try added the Limit process, still the rows rendered duplicate.

This is my view configuration:

How to resolve this?

I found out the duplicate rendering is due to my coding execute function setup() twice though I only call it once. I think it is related to the MVC framework I use. I'll check further.
