At this moment it is not possible to edit dates using the plugin-nuxeo-web-ui framework.
When trying to edit a date field what happens is that the new date is written without erasing the previous one, making the first date to prevail.
How to reproduce
- edit a ftest(ex: create_doc.feature) making it possible to edit a date field
- run the test
- the date is never edited
I made a workaround for now in my project by changing a step definition by making the date to be erased when it has any value:
Note: This is probably something that can be fixed in layout.js
