[snip]
GtkWidget *page_1(GdaConnection *conn)
{
	GtkWidget *vbox;
	GdaQuery *query;
	GdaDict *dict = gda_dict_new();
	gda_dict_set_connection(dict, conn);

	query = gda_query_new_from_sql(dict, "SELECT * FROM account", NULL);
	GdaDataModel *acc_list_model = gda_data_model_query_new(query);
	g_object_unref(query);
	
	query = gda_query_new_from_sql(dict,
			"SELECT * from account"
			"WHERE acc_id=##/*name=:'acc_id' type:gint descr:'account id'*/",
			NULL);
	
	GdaDataModel *payment_model = gda_data_model_query_new(query);
	g_object_unref(query);

	GdaParameterList *params =
gda_data_model_query_get_parameter_list(GDA_DATA_MODEL_QUERY(payment_model));
	GdaParameter *param = gda_parameter_list_find_param(params, "acc_id");
	

    GtkWidget *grid = gnome_db_raw_grid_new(acc_list_model);
	GtkWidget *form = gnome_db_raw_form_new(payment_model);
	
	gtk_box_pack_start(GTK_BOX(vbox), grid, FALSE, FALSE, 3);
	gtk_container_add(GTK_CONTAINER(vbox), form);

	return vbox;
