Read-only mode allows editing on formview for some field types

[joshirio]

While in table view, in read only mod (cloud sync), data cannot be changed, in formview it is allowed on specific field types like combo, image, files and others.

It should also block changes to the layout.
Maybe a new setReadOnly function for FormView is required...

EDIT: further inspection shows that also in table view there are some fields like image and others that still allow editing...
