Re: [gnome-db] GdauiDataStore gives incorrect values

[Gergely Polonkai <gergely polonkai eu>]

Hello,

I’m using 5.1.2 from the Fedora 20 repository.

I have a function ag_db_select(), which returns a GdaDataModel *. Here
is an exerpt of my actual code:

    {
        GdauiDataStore *store;
        GtkTreeIter    iter;

        store = GDAUI_DATA_STORE(gdaui_data_store_new(result));

        if (gtk_tree_model_get_iter_first(GTK_TREE_MODEL(store), &iter)) {
            gint test_int;

            gtk_tree_model_get(GTK_TREE_MODEL(store), &iter, 0, &test_int, -1);
            g_warning("Found row: %d", test_int);
        } else {
            g_warning("No such row!");
        }
    }

    value            = gda_data_model_get_value_at(result, COLUMN_ID, 0, NULL);
    save_data->db_id = g_value_get_int(value);

This sends the warning to my terminal "Found row: 41413296", while
setting save_data->db_id to 1 (the value I expect).

To test my case, I have created a small sample as you requested. I put
it in a gist: https://gist.github.com/gergelypolonkai/760fc710b56cb6b77ea5

It produces two "Found row" warnings as expected, but the first
warning contains totally bad values for me.

Thank you in advance!

Best,
Gergely
