This looks wrong too:
List<Participation> participationList = exModel.getEx
().getParticipationList();
ListView subjectListView = new ListView("list",
participationList) {
if your experiment model is intended to be a detachable one, ie. if you are
loading it from a database or something, then you shouldn't instantiate the
listview with a list but with a model that loads that list (or delegates to
another model that eventually loads the entity to which the collection
belongs...). If you pass the plain collection you are defeating the entire
purpose of having the loadabledetachablemodel in the first place. For
example, use new ListView("list",
new PropertyModel(exModel, "participationList"));
