Can u help me?

The reported '0' value is probably a number.
This is not allowed by the "Update" interface specifications, which only allow string objects or byte arrays as field values.
This is considered as a fatal error for Lightstreamer, as type constraints should be checked and enforced by the Data Adapter.

I'm sorry, last time i have the same error like this and you helped me. I forgot.
Thanks Dario.
