Have a little more information, by changing the hbm file for my
Permission entity slightly, the error I get now is :
OzoneHR.Domain.Core.Authorisation.Permission' is not a field on the
target object which is of type 'System.Collections.Generic.List`1
[OzoneHR.Domain.Core.Authorisation.Permission]
I changed the type from HashSet to List to see if that would make any
difference too.
The "test" I'm running to produce it is :
public void CanSaveProcessSetWithRoleAndPermission()
{
Role role = new Role("manager");
Permission permission = new Permission
("candosomethingmeaningful", null);
ProcessSet processSet = new ProcessSet("test process
set");
processSet.SetPermissionOnRole(role, permission);
_sessionManager.OpenSession().Save(permission);
_sessionManager.OpenSession().Save(role);
_sessionManager.OpenSession().Save
(processSet);
}
The SetPermissionOnRole method looks like:
public virtual void SetPermissionOnRole(Role role, Permission
permission)
{
if (!_rolePermissions.ContainsKey(role)) _rolePermissions
[role] = new List<Permission>();
_rolePermissions[role].Add(permission);
//_processSetRolePermissions.AddPermissionToRole(role,
permission);
}
Thanks,
Matt
