 Unbound messages are always considered as transition messages.
 
--   Bound transition messages are shown in a new message dialog also in edit mode if a dialog is already open \(for example, an action parameter dialog\). Only messages with targets that are the same as the fields within the original dialog are shown inline in the same dialog.
 
--   Bound transition messages triggered from an action without a dialog are shown in a message popover in edit mode alongside any existing state messages.

+Bound messages (both state and transition) are shown in a message popover in edit mode. The message popover allows the display of a summarized list of different types of bound messages. In addition, it provides a handy and systemized way to navigate and explore details for every message. The messages for subitems are also shown. Messages are also grouped by the name of the message group the current item belongs to, or else categorized under ‘General’.

-A message popover is used to display a summarized list of different types of bound messages \(messages that are specific to a particular instance, for example for a sales order selected in a list report and shown in an object page\). It provides a handy and systemized way to navigate and explore details for every message. The message popover automatically displays messages that are sent from the back end as part of the request-response cycle. The messages for subitems are also shown \(for example, if the message popover is bound to a sales order item, the messages for the underlying sales order items are shown as well\). In addition, messages are grouped by the name of the message group the current item belongs to, or else categorized under ‘General’.
+Bound transition messages, unlike the state messages, are always removed whenever the user triggers a new action or changes data.
