vhogberg opened a new issue, #43086: URL: https://github.com/apache/superset/issues/43086
### Bug description **The issue** The distribute across field uses `validateNonEmpty`, but its `initialValue` returns `[getTemporalColumns(state.datasource).defaultTemporalColumn]`. With no default temporal column that's `[undefined]`, an array of length 1, which passes validation and leaves you with a not so user-friendly error message. **Steps to reproduce** 1. Create a Box Plot on a dataset with no default datetime column. 2. Only `Metrics` is marked required; `Distribute across` is not. 3. Fill in `Metrics` only and create chart -> error. 4. Add then remove a column in `Distribute across` -> only now is it flagged as required. `Distribute across` should be be flagged as required on first load when empty. Datasets that do have a default datetime column auto-populate the control, so the issue isn't visible there. ### Superset version 6.1 ### Screenshots/recordings <img width="633" height="141" alt="Image" src="https://github.com/user-attachments/assets/09a938dd-de66-4028-9d26-c0bd2ec71f02"; /> <img width="345" height="427" alt="Image" src="https://github.com/user-attachments/assets/919cc633-569b-4944-a183-146de90c3dd2"; /> ### Superset version 6.1.0 ### Python version Not applicable ### Node version Not applicable ### Browser Chrome ### Additional context _No response_ ### Checklist - [x] I have searched Superset docs and Slack and didn't find a solution to my problem. - [x] I have searched the GitHub issue tracker and didn't find a similar bug report. - [x] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section. -- This is an automated message from the Apache Git Service.
