    <p>Hi I have a one to many ComplianceSet -> ComplianceItem. ComplianceItem has a one to many ComplianceItem -> ComplianceItemInstance. </p> <p>I have</p> <p>ComplianceSet</p> <p><code>HasMany(x =&gt; x.GetUserComplianceItems()).Inverse().Access.CamelCaseField(Prefix.Underscore).LazyLoad().Cascade.AllDeleteOrphan(); </code></p> <p>And</p> <p>ComplianceItem</p> <p><code>HasMany(x =&gt; x.GetUserComplianceItemInstances()).Inverse().Access.CamelCaseField(Prefix.Underscore).LazyLoad().Cascade.AllDeleteOrphan(); </code></p> <p>Then in my code I have </p> <p><code>userComplianceSet.GetUserComplianceItems().FirstOrDefault(....); ... userComplianceItem.RemoveUserComplianceItemInstance(userComplianceItemInstance);</code></p> <p>this code returns </p> <p>deleted object would be re-saved by cascade (remove deleted object from associations)[DecisionCritical.Core.Domain.UserComplianceSet#12]</p> <p>Now this is very frustrating. If I remove the cascade from both collections the code returns success but the db show's that it didn't do anything. the ComplianceItemInstance.ComplianceItemId field is still populated and of course the item is still there. In anycase, I just want to be able to delete a child from a collection, call save on the object holding the collection and have the freakin thing go away. I've tried all manner of permutations of cascade, save ( saving the set, saving the item ) adding delete to the ComplianceItemInstance and so and can't get this to work. </p> <p>Please help</p>

    1. COWhat's the code of RemoveUserComplianceItemInstance?

    2. COOk so I figured out what the issue is and I think Ilya was about to point me in this direction. because this is a bi-directional relationsip I must set the UserComplianceItemInstance.UserComplianceItem = null before saving the parent.

    3. CONow I tried all manner of things, one of which was to make it a unidirectional reference, however, ( and I didn't know this at the time ) if the fk is set to not null in the db table a unidirectional reference wont work because it saves the child with a null fk then does an update of the child with the fk. I was getting the 'can't insert null in fk' error and assuming I was on the wrong track. Anyway, all better now. albeit a couple days of life less. Can I mark plus one for figuring out my own answer? :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
