Problem

-- a service has 2 components : a Map (as initial component) and a Post Enveloping

-- for each message, custom attributes are set in the map

-- all message are enveloped

-- the Post Enveloping component is executed

-- custom attributes that were set in the map cannot be retrieved in the Post Enveloping. Only few of them are available

Resolution

* it is not a valid use case. if there are thousands of messages being enveloped, B2bi cannot store all attributes in the enveloper

* solution must be redesigned. For instance by adding the attribute values in the content of the message (in the first map)
