Hello, I have an EJB with a collection variable of some entities declared as: | @In(create = false, required=false) @Out(required=false) | private Collection<myEntity> myEntitiesList; | Before using the outjected collection inside a datatable in the view, I have a previous action that initialize the collection with some content. I also have action method to update the collection after it gets modified by the view. I use this EJB for many porpuses so the collection must not be always required. At the moment I annotate the collection with the @IN annotation, the outjected collection outjected as an empty collection (or maybe not outjected at all, I'm not sure), At the moment I remove the @IN annotation, the collection is outjected with all of its content, but then, obviously the update method does not work and the collection is not affected by the view modifications. What am I doing wrong here? Thanks a lot. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962795#...
