"Start Date" not populating when user changes status from "Not Started" to "In Progress"

Question

**UPDATE: Just came across this from Esri: https://support.esri.com/en-us/knowledge-base/error-arcgis-field-maps-domain-com-esri-arcgis-runtime--000031889.  In the meantime, I am just going to turn them back into DateTime fields.

I created 2 fields: esritask_startdate and esritask_enddate. I wanted to add an automatic update field on each one for when the user changes the status (just how the default task configuration is set up). When I test this out in field maps, nothing gets populated in either date field when I change the status. The expression I have on both is just today(). Could this be because it is a Date Only field?

P.S. why are Date Only fields still an issue? I want to make the esritask_duedate a Date Only field and it still isn't supported in Field Maps. I am on Field Maps 25.3.0 and according to this article, it should support Date Only fields.

Hi @apgis16 ,

DateOnly fields should work for your start and end date fields, with automatic calculations, after you update to Field Maps 26.1.1. The "What's New" article you originally posted was from March 2026 when Field Maps 26.1 was originally released, not for version 25.3.

I just did a quick test and created DateOnly start date and end date fields and used two different arcade expressions - Today() and DateOnly(Today()) and they both calculated successfully from a Tasks edit action.

If you update to the newest version of Field Maps and it still doesn't work, please let us know.

Can you possibly break down the steps you are taking to see whether the issue is upon starting an edit session? It might be that is waiting for trigger in order for those fields to populate but I would need to test and see if that is an issue upon either editing or starting an edit session.

Try also simply adding return DateOnly(Today()) or some combination to see if that comes up with anything.

Thank you! Just tried that and saw no errors but when I check the record, it's blank. I also just found this from Esri................: https://support.esri.com/en-us/knowledge-base/error-arcgis-field-maps-domain-com-esri-arcgis-runtime--000031889
