> Hi again.
> I think there is a bug in action TRANSFER when it comes to transferring - or better not transferring - values from a feature of kind A to a feature of type B, where both features have the same identifier. Such an attempt throws an exception in cases where values cannot implicitly be converted. An example:
> Text:
> {noformat}
> alpha beta{noformat}
> Script:
> {noformat}
> DECLARE T1 (Annotation a, STRING ID);
> DECLARE T2 (STRING a, INT ID);
> w:"alpha" {-> CREATE(T1, "a" = w, "ID" = "3ef9")};
> T1 {-> TRANSFER(T2)};{noformat}
> Expected output (new annotations):
>  * {type: T2, begin: 0, end:5, features:{}}
> But throws:
> {noformat}
> org.apache.uima.cas.CASRuntimeException: Trying to access value of feature "Main.T2:a" as "uima.cas.String", but range of feature is "org.apache.uima.ruta.type.RutaBasic".{noformat}
> My suggestion is to only transfer values between features if they are of the same kind, for consistency's sake.
> Best, Michael
