I am using Guid's a Primary Keys and also as Rowguid's for replication. The issue is on update's, If a field is specifed as rowguid it cannot be updated so the update fails.

I made the following changes to make this work can you please add to your code so I dont break at next update? or let me know how and what you want to change so I dont get a suprise next update

Thanks

Paul

To Business layer I added this Property. (with a private as well)

''' <summary>

''' Gets or sets a value that determines whether the primary key for this business object is

''' a RowGuid

''' </summary>

''' <value></value>

''' <returns></returns>

''' <remarks></remarks>

<Category(EDITOR_CATEGORY_CRUD), _

DefaultValue(True), _

Description("Determines whether the primary key for this business object is a RowGuid.")> _

Public Property PrimaryKeyIsRowGuid() As Boolean

Get

Return Me._PrimaryKeyIsRowGuid

End Get

Set(ByVal value As Boolean)

Me._PrimaryKeyIsRowGuid = value

End Set

End Property

 

And in Data Layer

In method BuildUpdateInfo aroung line 573

'----------------------> Paul made a change the code here from

'--this

'-- Add the pk field to the fields to update if the primary key if not

' auto incremented

' If Not Me._BusinessObject.PrimaryKeyIsAutoIncremented Then

' loInfo.Fields.Add(lcFieldName)

' End If

'---> to

'-- Add the pk field to the fields to update if the primary key if not

' auto incremented or Row-Guid

If Not Me._BusinessObject.PrimaryKeyIsAutoIncremented AndAlso Not Me._BusinessObject.PrimaryKeyIsRowGuid Then

loInfo.Fields.Add(lcFieldName)

End If

Chan,

Thats what I thought as well but excluding the PK from the fields to update causes another exception to be thrown as then the business object thinks there is no primary key

Paul, did you try adding the PK field name to the FieldsToExcludeFromUpdate?  That should do the same thing... if it doesn't then yeah we'll probably add a field called PrimaryKeyIsUpdatable (so it handles more than just RowGuids).

Ben,

Yeah I tried that first but it complains that there is no Primary Key Field. It makes sense once you step through that method why it doesn't work. PrimaryKeyNotUpdatable work's just let me know what ya end up doing.

Thanks

Paul
