I have an entity with children. I need to loop through the children
and update a date time field. When I try to save the parent (item) or
the child (doc) I get the Don't change the reference to a collection
with cascade="all-delete-orphan" error. Funny thing is I don't think I
am changing the reference to the collection, just setting a date
field.
I get this error whether I save with the parent _opsItemRepository or
the _OpsItemRepository.
var item = _OpsItemRepository.Get(OpsItemId);
if (item != null)
{
foreach (var doc in item.OpsDocs)
{
var fullFileName = Path.Combine
(TIFDestinationPath, doc.OpsDocId + ".TIF");
if (!doc.Exported.HasValue)
{
if (File.Exists(finalFileName))
{
doc.Exported = DateTime.Now;
_OpsDocRepository.SaveOrUpdate(doc);
}
}
}
}
Any ideas?
Thanks,
Nigel
