I recently upgraded from 4.3.12 to 4.3.14. I notice now ( but this could be due to a previous update ) that dexterity richtext fields are not shown anymore.
They are displayed as RichTextValue object. (Did you mean .raw or .output?)
Editing the page shows the richtext widget with the proper content.
These dexterity objects are 100% TTW ( they are just forms which several compulsory fields )
It seems that this "RichTextValue object. (Did you mean .raw or .output?)" sentence is referenced many times on the internet by google
I guess some widget template has changed. Likely candidates are somewhere in z3c.form, plone.app.z3c.form or plone.app.textfield.
I ran into something similar for indexing the value of a richtext field:
So no definitive answer, but maybe this points you in the right direction.
I investigated a bit more. This was introduced in plone.app.textfield 1.2.8 because of the changes made in this pull request. Pinning back to 1.2.7 fixes it and seems fine: you are only missing a new feature then.
I will open an issue.
