Hi there,
tagpickerproblem.zip (91.9 KB)
the TagPicker is buggy I think: pick a tag, save the entity with a many-to-many association to the tag entity, then try to open this entity in the browser again. Sometimes it works, sometimes it throws an unfetched attribute error.
And even though you don’t edit the value in the TagPicker, the screen is set dirty and a dialog with the question asking if you want to save any unsaved data appears.
See test project and video:
