QGIS » QGIS Application

Aloha,

I loaded geospatial view from Oracle (11g) in QGis 2.4.
When I query on attributes, string like attributes are all right padded with white space character (in the follow exemple, TYPE_LIB and AFF_LIB). My view seems correct when I query with sql on it in sqlplus.

Here the sql I used to create the view :

CREATE OR REPLACE FORCE VIEW "QGIS"."EXPORT_PA_LIBEL"
(
"GID",
"GEOMETRY",
"INSEE_CO",
"RIVOLI_V",
"LIBELLE",
"TEXTE_L",
"TEXTE_L_X",
"TEXTE_L_Y",
"TEXTE_L_O",
"TYPE_LIB",
"AFF_LIB"
)
AS
SELECT GID,
GEOMETRY,
CAST (INSEE_CO AS CHAR (5)),
CAST (RIVOLI_V AS CHAR (4)),
CAST (LIBELLE AS VARCHAR (200)),
CAST (TEXTE_L AS VARCHAR (200)),
CAST (TEXTE_L_X AS VARCHAR (50)),
CAST (TEXTE_L_Y AS VARCHAR (50)),
CAST (TEXTE_L_O AS VARCHAR (50)),
CAST (TYPE_LIB AS CHAR (50)),
CAST (AFF_LIB AS CHAR (50))
FROM PA_LIBEL
WITH READ ONLY;

Here a screenshot of attributes def in QGis.

Is this a known problem ? Am I missing something ? It's pretty annoying when I intend to put etiquettes on features.

Thanks in advance
