So I have this schedule visit page with two groups.
Group 1 contains a list of: Cases.
Group 2 contains a list of: Parties.

each group has a checkboxes next to its item for the user to select.

My Issue when i select a case and/or a party and save -- then go to the edit page of the visit i just saved and only my selected case is checked and the party i selected is not checked. After debugging i realized that the partyId is not being saved properly during the create page and thus not showing as selected or saved on the edit page.

I really need help on how to properly save the party selected and setting for it a value from the parameter. Here is my code of what i have for saving a case and would like to know how to properly save with party.

Controller

[HttpPost]
    [ValidateInput(false)]
    public ActionResult Create(VisitViewModel viewModel, Guid[] associatedCasesSelected, Guid[] selectedParties)
    {
        if (!ModelState.IsValid)
        {
            viewModel.Time = _timeEntryHelper.Value;
            AddLookupsToViewModel(viewModel);
            return View(viewModel);
        }
        var visitEntry = Mapper.Map<VisitViewModel, VisitEntry>(viewModel);
        ...
        viewModel.CasePartyIds = selectedParties;
        try
        {
            _visitEntryService.Create(visitEntry, associatedCasesSelected);
            this.FlashInfo(string.Format(Message.ConfirmationMessageCreate, Resources.Entities.Visit.EntityName));
        }
        catch (RulesException ex)
        {
            ex.CopyTo(ModelState);
        }
        if (ModelState.IsValid)
            return RedirectToAction("Edit", "Case", new { caseId = viewModel.CaseId });
        AddLookupsToViewModel(viewModel);
        return View(viewModel);
    }

VisitEntryService

public void Create(VisitEntry visitEntry,IList<Guid>caseIds)
    {
        EnsureValid(visitEntry);
        _visitEntryRepository.Save(visitEntry);
        caseIds = AddCurrentCaseToCases(visitEntry.CaseId, caseIds);
        foreach (var caseId in caseIds.Distinct())
        {
            var visit = new Visit {CaseId = caseId, VisitEntryId = visitEntry.VisitEntryId};
            _visitService.Create(visit);
        }
    }

AddCurrentCaseToCases

 private static IList<Guid>AddCurrentCaseToCases(Guid caseId, IEnumerable<Guid>caseIds)
    {
        var cases = new List<Guid>();
        if (caseIds != null)
        {
            cases.AddRange(caseIds);
            if(!caseIds.Contains(caseId))
                cases.Add(caseId);
        }
        else cases.Add(caseId);
        return cases;
    }

VisitService

public Visit Get(Guid visitId)
    {
        return DataContext.Visits.SingleOrDefault(v => v.VisitId == visitId);
    }
    public void Save(Visit visit)
    {
        if(visit.VisitId == Guid.Empty)
        {
            visit.VisitId = Guid.NewGuid();
            DataContext.Visits.InsertOnSubmit(visit);
        }
        else
        {
            var currentVisit = Get(visit.VisitId);
            if (currentVisit == null) throw RepositoryExceptionFactory.Create("Visit", "VisitId");
        }
        DataContext.SubmitChanges();
    }

Any TIPS or IDEAS is greatly appreciated at this time :) The entitiy for the parties will be VisitEntryParty
