State Discrepancies

Statelessness has a relevant consequence, which users can find disorienting at first: the state of the browser is not necessarily synchronised with the content of the database. For instance, if someone else adds an entity, it will not show up in your main or selection lists, at least until you re-filter their content, or move around with arrows.

Correspondingly, it is possible that you deleted, say, a relationship, without breaking any cardinality constraint: however, since in the mean time another user has deleted other relationships, your operation becomes illegal. In this case ERW will warn you, and show you again the form you were editing (this time, with updated information about the database content).
