Hi

I have used the follwing generic ConcurrencyFilterFactory with self serving before but it does not work with adapter. FieldCompareValuePredicate only accepts an IEntityField. I am still a bit of a noob when it comes to llblgen pro so I am sure I have missed something simple.

Thanks for any help

Public Class ConcurrencyFilterFactory
    Implements IConcurrencyPredicateFactory

    Public Function CreatePredicate( _
    ByVal predicateTypeToCreate As ConcurrencyPredicateType, ByVal containingEntity As Object) _
     As IPredicateExpression Implements IConcurrencyPredicateFactory.CreatePredicate

        Dim predicate As IPredicateExpression = New PredicateExpression
        Dim entity As EntityBase = CType(containingEntity, EntityBase)

        Select Case predicateTypeToCreate
            Case ConcurrencyPredicateType.Save, ConcurrencyPredicateType.Delete
                predicate.Add(New FieldCompareValuePredicate(entity.Fields("TimeStamp"), ComparisonOperator.Equal))
                Exit Select
        End Select

        Return predicate
    End Function

change:

 predicate.Add(New FieldCompareValuePredicate(entity.Fields("TimeStamp"), ComparisonOperator.Equal))

into:

 predicate.Add(New FieldCompareValuePredicate(entity.Fields("TimeStamp"), null ComparisonOperator.Equal))
