I’ve just stumpled across something very, very strange. Be careful when deploying a custom type, which has a property type of datetime. Using using the createData and setData methods won’t always work!Even when supplying with a valid date, such as #now()#;.I found I had to move to using date as the property type, and suddenly everything started consistently working. I haven’t taken the time to dig into it, but it is very strange, because both datetime and date create the same database column when FarCry deploys your custom type.
