I will try to use the following approach now:
- create a SFSB that acts as value for the selectManyListBox
build a custom converter which turns the id of a TEAM into an object of CollectionPersonTeam (for a given person) and returns the team id for a given CollectionPersonTeam
create a Service that
- retrieves all CollectionPersonTeams for a given person
- fulfils CRUD operations on CollectionPersonTeam when called wiht a person and a team as parameter
Do you think this will work? Or can I use the existing EntityHome and EntityList objects generated by Seam gen instead of a Service?
