DeepSave - A Few Questions / Issues

Hey guys,

I am just getting started with netTiers, but I think I may have run into a bug.

I am able to DeepLoad a Listing:

            listing = listingService.DeepLoadByListingID(listingID, true,
                DeepLoadType.IncludeChildren, typeof(TList<ListingToTag>));

This works fine, and then I try to remove all the child elements from the ListingToTag collection:

            while (listing.ListingToTagCollection.Count > 0)
                listing.ListingToTagCollection.RemoveAt(0);

Is there a RemoveAll() function that I am missing here?

Then on to the DeepSave call:

            listingService.DeepSave(listing, DeepSaveType.IncludeChildren, typeof(TList<ListingToTag>));

This call is saving the Listing data, but it does not remove the ListingToTag elements.

Any ideas why this is not working?

Thanks,

Grier


 

You should use the "MarkToDelete()" method to indicate an entity should be deleted when you do a DeepSave.

ie. listing.ListingToTagCollection[ n ].MarkToDelete();

swin,

just to clarify...

if you use  listing.ListingToTagCollection[ n ].MarkToDelete(); then the entity in the TList has its entitystate changed to Deleted. It will be deleted on the database but will it then be deleted from the TList? Unless something has changed i don't think so.

i thought we were supposed to use RemoveEntity() which calls MarkToDelete() and moves the entity to the DeletedItems collection in the TList. The datalayer the deletes those items from the database and deletes them from the DeletedItems Collection so that the retruned TList is consitent with the the database

correct?

Vin,

Yes, you are quite correct.  In the instances where I had been using MarkToDelete I wasn't doing anything with the collection after the DeepSave so it made no difference to me, but as you quite rightly state the TList is more consistent with the database when using the RemoveEntity method - so that should be the prefered usage.

Thanks guys -

Should this approach be working for netTiers v2.0?  If so, neither of these techniques have been successful in solving the issue.  If this is a bug in the current version of netTiers, where can I make the modification that will have this work properly?  Do I need to use one of the nightly builds?  I would rather not use one of these builds unless I can be assured that the build is free of bugs.

Thanks,
