Still the same error:
| public String delete()
| {
| String id = FacesContext.getCurrentInstance()
| .getExternalContext().getRequestParameterMap()
| .get("selectedId");
| selectedSpielplatz = dao.findById(Long.valueOf(id), false);
| selectedSpielplatz=dao.merge(selectedSpielplatz);
| dao.makeTransient(selectedSpielplatz);
| selectedSpielplatz=null;
| return "list";
| }
|
But I dont understand, that if I load the object(selectedspielplatz) why it is
not managed.
Why are the objects always detached?
I tried the same thing with glassfish and toplink and I haven't this problem.
Is it really necessary always to merge before making an operation, or is it
possible to reconfigure something, maybe entity manager per session?
