Failed to convert parameter value from a Guid to a String

Hi,
I am trying to use the Microsoft Oracle data provider to store a GUID as a
string.

Get this message:

Message:
Failed to convert parameter value from a Guid to a String.

Inner Message:
System.InvalidCastException: Object must implement IConvertible.
at System.Convert.ChangeType(Object value, Type conversionType,
IFormatProvider provider)
at System.Data.OracleClient.OracleParameter.CoerceValue(Object value,
MetaType destinationType)"

This does work with the Oracle Data Adapter for Oracle.

The field is a varchar2 on the database. We are using a DataAdapter (Oracle)
to fill a DataSet with.

The DataSet gets set up using a MSSQL DataAdapter. So the dataset have a
property to get the GUID value.

Getting it from the database into the dataset works fine, but when trying to
put the changed DataSet back to the database does not.
