I have added the following async remote service method (using 2.7.0.):
TransportTokenResponse<ProductDto>
findActiveDeclarationsOfActiveMember(TransportTokenRequest<Void> request);
TransportTokenResponse, just like TransportTokenRequest are interfaces with
both an abstract subclass and one concrete class.
The GWT console shows the following error:
ERROR] 'com.ited.lang.transporttoken.TransportTokenResponse' has no
instantiable subtypes
I am aware that using interfaces in RPC methods is tricky and can result in
bloat code, but in this case, I only have one concrete class, so why does
GWT complain and can't use the concrete class (it's in the same package as
the interface) ?
I noticed this is a new 2.7.0. warning, maybe it has something to do with
this
The details of TransportTokenResponse,:
public abstract class TransportTokenResponseBase<T> implements
TransportTokenResponse<T> {
private static final long serialVersionUID = 1L;
protected TransportTokenResponseBase() {
}
}
public final class SimpleTransportTokenResponse<T> extends
TransportTokenResponseBase<T> {
private static final long serialVersionUID = 1L;
SimpleTransportTokenResponse() {
}
}
