Findings

Enketo scrolls to the first non-readonly question, which in this case is a non-relevant dn. Not sure if this is a regression or an unusual case.

To Do

• [x] don't add goTo error handlers if URL has no fragment identifier? (why are they added?)

[pbowen-oc]

@MartijnR - If we don't pass in a URL parameter identifying a specific item to open to, the expectation is that it simply opens to the top of page 1. If it is doing something different, I think there has been a regression.

[MartijnR]

Thanks! Yes, I confirmed now that it is a regression in Enketo Core 7.2.3 (May 2023) https://github.com/enketo/enketo-core/pull/969

Thankfully, it looks like the fix in my PR restores the original behavior though the goto functionality would require special attention during testing.

[pbowen-oc]

@MartijnR - This is not working. We are still seeing the error. We also noticed that it is skipping the first page of a form when it only contains a note and going right to page to with input fields (no relevant logic in use and no goto item in use).

Using /single/fs/i/ the following form opened directly to the second page unexpectedly: multi-level_crf_v1-sm-v2.xform.txt

[MartijnR]

If you are still seeing the error, I would expect there to be a hash (#) part in the URL (which would mean OC requested the goto functionality). Could you post an Enketo URL please?

Wrt loading the second page, I'll try to reproduce.

• [x] reproduce issue with starting on page 2 - http://localhost:8005/single/fs/i/RUHOG9K0?ecid=a
• [x] reproduce in enketo/enketo and file bug report. This is not desired behavior, so would be a bug. xlsform - cannot reproduce with ODK-style form, seems to have to do with the discrepancy note on a non-first page. In particular the bind with the for attribute may be causing this. - The issue is in pages.js flipToPageContaining function
• [x] issue and PR to enketo/enketo https://github.com/enketo/enketo/issues/1285, https://github.com/enketo/enketo/pull/1286
• [x] duplicate fix in this fork since we may not be able to wait for a release of enketo-core?
• [x] undo duplicate fix after switching to monorepo

[pbowen-oc]

We are not seeing the error anymore. Our deployment was outdated. However, the issue with page 1 being skipped is still occurring.

[MartijnR]

The bug is present in any form whose discrepancy notes start on a page other than the first page. The form will load to that page.
