1. What is the issue? Please be detailed.
I want to pre-fill a question in a Web Form using URL parameters and the &d[/data/uuid]=foo XPath syntax.
This works perfectly in Enketo, using e.g. https://example.com/f/ABC?st=TOKEN&d[/data/uuid]=foo. If I switch to Web Forms in my self-hosted Central v2025.1, the field remains empty.
2. What steps can we take to reproduce this issue?
Create a simple form with a question of type text, named uuid, and try to pre-populate this field using the syntax mentioned above. Switch between Enketo and ODK Web Forms in the forms settings. I provide a minimal form example below.
3. What have you tried to fix the issue?
Read the question and answer by @LN here. @LN mentioned last year that ODK Web Forms will "likely" follow the same approach but I cannot find any further information on this and want to make sure this is on the roadmap.
Checked the feature matrix with XPath being 95% complete already. Checked the detailed project board / roadmap for Web Forms with no information on it. I might be using the wrong keywords because I am not a developer, though.
4. Upload any forms or screenshots you can share publicly below.
