I have an image in my database, I setup the business object mapper with CustomObject Type = System.Drawing.Bitmap and the flag serialize to true, null value option= don't allow null. I rebuild and get the following working code:

When I change the option null value option= return alternate on null/Set null on alternate(reference type) the code generated is the following:

It seems that the row

Me.BinaryFormatter.Serialize(loStream, value)   

gets missing. In fact I added it manually and all works fine.

Is there a better way to achieve this? Is this by design?

Thanks in advance

Thanks. I have never used the Custom Code option in the BO Mapper. I assume this is where I use the code you mentioned above. This seems to have allowed me to get the BO to compile. When I reference this picture column in a form bound to a picturebox, when the form displays I get this error:

An exception of type 'MicroFour.StrataFrame.Business.BusinessLayerException' occurred in MicroFour StrataFrame Business.dll but was not handled in user code

Additional information: An error occurred while refreshing the data from field 'tbvo_Groupi.GI_PICTURE' to property 'Image' on control 'pictureBox1.'  Are you missing FieldPropertyDescriptor for a custom property?

Not sure what this may be looking for?
