At the moment, the updated timestamp changes regardless of whether something actually changed in the entity or not.
It's added to tests and there is no problem :
Can you be more explicit?
Sorry, I didn't make too much sense.
Basically, if you save a form without changing any of the fields, the updated timestamp changes. This should only change if you actually change something in the entity shouldn't it?
yes it should not change if the entity has no changeset. The test pointed above should prove that it actually works as you expect.
Sorry, I found the issue. I had a listener that was modifying a collection.
