[Firebird-net-provider] request synchronization error

[Amanda K. <ak...@fl...>]

I'm trying to run an update of a dataset via a data adapter, and I get 
this error:

An unhandled exception of type 'FirebirdSql.Data.Firebird.FbException' 
occurred in system.data.dll

Additional information: request synchronization error


Any ideas of what could be causing it before I continue on my wild goose 
chase? I've done this many times before with all the same data types, my 
parameters are all spelled correctly and in the same order as the stored 
procedure. The error message is just so cryptic. Here's the update code:

                FirebirdSql.Data.Firebird.FbCommand cmd = new 
FirebirdSql.Data.Firebird.FbCommand();
                cmd = CreateSPCommand("SPADMINMDSCREENINFOUPDATE");
                cmd.Parameters.Add("@SCREENID", 
FirebirdSql.Data.Firebird.FbDbType.Integer, 4, "ScreenID");
                cmd.Parameters.Add("@OBJECTIVETRACKID", 
FirebirdSql.Data.Firebird.FbDbType.SmallInt, 4, "ObjectiveTrackID");
                cmd.Parameters.Add("@CAPTION", 
FirebirdSql.Data.Firebird.FbDbType.VarChar, 50, "Caption");
                cmd.Parameters.Add("@SCREENTYPE", 
FirebirdSql.Data.Firebird.FbDbType.VarChar, 15, "ScreenType");
                cmd.Parameters.Add("@MESSAGETEXT",

                cmd.Parameters.Add("@QUESTIONID",

                cmd.Parameters.Add("@OBJECTIVETIMEFRAMEID",

                cmd.Parameters.Add("@BACKSCREENID",

                cmd.Parameters.Add("@NEXTENABLED",

                cmd.Parameters.Add("@NEXTSCREENID",

                cmd.Parameters.Add("@FINISHENABLED",

                cmd.Parameters.Add("@DIGENABLED",

                cmd.Parameters.Add("@DIGDEEPERSCREENID",

                cmd.Parameters.Add("@PROMPTWAITTIME",

                cmd.Parameters.Add("@PROMPTMESSAGE",

                cmd.Parameters.Add("@MINDAYS",

                cmd.Parameters.Add("@MAXDAYS",

                FirebirdSql.Data.Firebird.FbDataAdapter da = new 
FirebirdSql.Data.Firebird.FbDataAdapter();
                da.UpdateCommand = cmd;
                da.InsertCommand = cmd;
               
                int intError = 0;
                intError = (int)da.Update(ds, "MDScreenInfo"); <==line 
that errors out


The CreateSPCommand code is as follows:

                FirebirdSql.Data.Firebird.FbConnection cn = new 
FirebirdSql.Data.Firebird.FbConnection();
                System.Configuration.AppSettingsReader settings = new 
System.Configuration.AppSettingsReader();
                cn.ConnectionString = 
settings.GetValue("ConnectionString", typeof(string)).ToString();
                cn.Open();
                FirebirdSql.Data.Firebird.FbCommand cmd = new 
FirebirdSql.Data.Firebird.FbCommand();
                cmd.Connection = cn;
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.CommandText = StoredProcName;
                return cmd;
