What's the correct way to check for no value in a pre-image.
If there's no value my plugin fails where prePort = .

                Entity preMessageImage = (Entity)context.PreEntityImages["InvitePortalImage"];
                // get field value
                prePortal = (bool)preMessageImage.Attributes["new_2020portal"];

HI Stuie,

you can check like

if(context.PreEntityImages.Contains(new_2020portal") && context.PreEntityImages[new_2020portal"] != null)

Hello there,

I use this one:

context.PreEntityImages["preImage"] != null

Then, is always a best practice check for null values before get the value from an attribute.

regards,
