Mobile Cache Not Saving Edits

KirmanieRavariere

I used the Create Mobile Map geoprocessing tool in ArcGIS 10's toolbox to generate a mobile map from an MXD. The MXD has one layer which featureclass is:

1) in a geodatabase
2) registered as versioned and
3) has a globalid

all the requirements for generating a mobile cache JUST to take advantage of ArcGIS Mobile's mapping capabilities.

I then took the MapSchema.bin file and dropped it in a folder on my Windows Mobile device. I wrote a small test Smart Device application in Visual Studio that has this code:

            using (MobileCache cache = new MobileCache(mobileCachePath))
            {
                cache.Open();

                FeatureLayer layer = cache.Layers[0] as FeatureLayer;
                FeatureDataTable table = layer.GetDataTable();

                FeatureDataRow row = table.NewRow();
                row["area_id"] = 1;
                table.Rows.Add(row);

                int recordsAffected = table.SaveInFeatureLayer();
                //recordsAffected is always 0


                using (FeatureDataReader reader = layer.GetDataReader(null, null))
                    while (reader.Read())
                    {
                        //never reaches here
                    }

                table = layer.GetDataTable(new QueryFilter("area_id=" + 1));
                int foundRows = table.Rows.Count;
                //foundRows is always 0

                cache.Close();
            }

As you can tell from the comments in the code, I can't find my new records anywhere. I open the MobileCache.db file in a Sqlite browser and the tables are empty. I read that I could use the MobileCache in a headless fashion, is this not what ESRI meant? Can anyone fill me in on what I'm missing?

I'm working with 9.2 Mobile migration project for 10. To resolve this issue you need to add the command reader.Close() soon after the end of your code.
Sample:

                using (FeatureDataReader reader = layer.GetDataReader(null, null))
                    while (reader.Read())
                    {
                      //editions
                    }
if (reader!= null && !reader.IsClosed)
                    reader.Close();
