Hi Guys,

FYI we use "return alternate on null > Nothing" for TimeStamp columns and that works fine to.

I say this because I'm pretty sure the we get a "System.DBNull' to type System.Byte[]" error if we don't get the Timestamp setting correct in the BO Mapper.

Cheers, Peter

Cool!

Thanks! I used new byte[] {} in the alternate and that worked.

I'm not sure if one of the "return alternate on null" settings would work in this situation, but you could just put your custom code in the custom code area of the BO Mapper (the big text box at the bottom of the field customization form). That way every time your BO is rebuild within the mapper, this code gets used.

Hi, I am reading an image field from the database into a property of type[]. When the field is null, I get an Unable to cast object of type 'System.DBNull' to type 'System.Byte[]  error. I have changed the StrataFrame generated code for the BO to fix it, but is there some setting that I need to make when generating the BO so this is automatically handled correctly in the generated BO?
