Version: LLBLGen Pro v3.1 Final (June 17th, 2011) Target Framework: LLBLGen Pro Runtime Framework Target Platform: .NET 4.0 Template Group: SelfServicing - General2010 (With additional custom templates)

I am migrating WinForms projects from v2.6 & .NET 3.5 to v3.1 & .NET 4.0 I've gotten everything to build and validated all my method signatures.

I am having an issue with controls bound to child entity related fields.

My main entity in this example is an OrderHeader which has a related collection of OrderDetail entities called OrderDetails. OrderDetail has related fields PartDescription (Part.Description) and PartRevisionDescription (PartRevision_.Description). My form has BindingSources (orderHeaderEntityBindingSource.DataSource = typeof(OrderHeaderEntity)) and (orderDetailBindingSource.DataSource = orderHeaderEntityBindingSource; orderDetailBindingSource.DataMember = "OrderDetails").

Everything bound to orderHeaderEntityBindingSource binds fine. orderDetailBindingSource is bound to a DataGridView and several other UI controls. I have two TextBox controls bound to (orderDetailBindingSource - PartDescription) and (orderDetailBindingSource - PartRevisionDescription). When the form loads in debug mode I get an ArgumentOutOfRangeException on this code:

        /// <summary> setups the sync logic for member _partRevision_</summary>
        /// <param name="relatedEntity">Instance to set as the related entity of type entityType</param>
        private void SetupSyncPartRevision_(IEntity relatedEntity)
        {
            if(_partRevision_!=relatedEntity)
            {       
                DesetupSyncPartRevision_(true, true);
                _partRevision_ = (PartRevisionEntity)relatedEntity;
                this.PerformSetupSyncRelatedEntity( _partRevision_, new PropertyChangedEventHandler( OnPartRevision_PropertyChanged ), "PartRevision_", ABS.BusinessObjects.RelationClasses.StaticOrderDetailRelations.PartRevisionEntityUsingPartNumberPartRevisionStatic, true, ref _alreadyFetchedPartRevision_, new string[] { "PartRevisionDescription" } );  // ArgumentOutOfRangeException HERE!!!
            }
        }
        
        /// <summary> setups the sync logic for member _part</summary>
        /// <param name="relatedEntity">Instance to set as the related entity of type entityType</param>
        private void SetupSyncPart(IEntity relatedEntity)
        {
            if(_part!=relatedEntity)
            {       
                DesetupSyncPart(true, true);
                _part = (PartEntity)relatedEntity;
                this.PerformSetupSyncRelatedEntity( _part, new PropertyChangedEventHandler( OnPartPropertyChanged ), "Part", ABS.BusinessObjects.RelationClasses.StaticOrderDetailRelations.PartEntityUsingPartNumberStatic, true, ref _alreadyFetchedPart, new string[] { "PartDescription" } );  // ArgumentOutOfRangeException HERE!!!
            }
        }

If I suspend binding on orderDetailBindingSource before the orderHeaderEntityBindingSource.DataSource is set I get no error. If I remove the TextBox control bindings for PartDesctipion and PartRevisionDescription I get no error. I had no issues with this in v2.6 and .NET 3.5.

Help me! Help me, please please please!!!

How exactly are you binding to the bindingSource? (by code? design view?)

The bindings are all set in the form.designer.cs I don't beleive there are any places outside of the designer code that change the bindings in this example.

I can't reproduce it with the latest LLBLGen v3.1 build. See my attached example. Please see if you can reproduce it there.

If you can't reproduce it with my Northwind example, then something is going on in your code. Please see if you can cook a repro project we can use to reproduce the problem. You can open a HelpDesk thread (private) to do that.
