Stuart Douglas commented on JBSEAM-4497:
----------------------------------------

I have a conversation scoped converter like this that works quite well, in the getAsString method it generates a unique string and sticks the <String,Object> pair into a hashmap, in the getAsObject method it simply looks up the string in the map. As long as the objects are serialisable it should work in a clustered environment as well, the main restriction is that it only works in a long running conversation.

> It would be awesome if we could have an <s:convertPojo key="<unique field>"> component with a key attribute that identifies a unique key in the pojo to do translation with.  ie. s:convertEntity uses the primary key of the entity but convertPojo could be used for entities that are not in the database yet if for instance the name was a unique.  Also, it could just be used for pojos from a webservice or something for that matter.  It could even throw a NonUniqueException if in the list of pojo's it finds two with the same exact key so people use it correctly and an exceptions is thrown when not used correctly so we know.  Anyways, just thought this would be a nice feature add to an already pretty damn sweet toolbox called seam.
