Hello,
I am using EF with Firebird for some time now and it works very fine.
When I submit a new record via EF i wrap it into a try{} catch{} and want to
to recover in a gentle way. Eg. The new record violates the PK. In this case
I set the current entity to state detached. This works ok unless the entity
has navigation properties that have been populated.
this._ctx.Entry(this.NeueBaustelle).State = EntityState.Detached;
In this case I tried to detached them before the main entity:
foreach (BAU2ORG bau2org in this.NeueBaustelle.BAU2ORG)
{
this._ctx.Entry(bau2org).State = EntityState.Detached;
}
Unfortunatly I receive a collection has changed error. Therefor I tried
this:
this.NeueBaustelle.BAU2ORG.Clear();
So far I do not get any troubles (tests are in progress).
What is the best way to handle error conditions during save with navigation
properties?
Thanks
Niko
