Campos Blob con DBExpress

[lgluna]

Ayuda:

Actualmente estoy utilizando DBExpress para conectarme con DB2 pero tengo un problema.

Cuando utilizo campos Blob(para imagenes) me marca el siguiente error:

Cwbdb_RetrieveLobData Returned Error Code 6038
Cause: The Length of the parameter value is either too Short o to Long

Estoy utilizando el siguiente DBEXpress:

y aparentemente si soporta campos Blob por lo siguiente:

****************************************************
LOB support
-----------
If using Client Access/400 V5R1 or later and OS/400 V4R5 or later, LOBs may
be utilized. By default LOBs are returned as LOB locators from AS/400 and fetched on
demand. This is also the default mode implemented in dbexpca400. There is an option
implemented in this driver that enables returning of "Inline" BLOBs as part of the
result set. This means that the BLOB is always fetched. If it makes sense to your
application, you may set a LOB threshold. If you set LOB threshold to for example
16384 by appending /lobthreshold=16384 to ROLENAME parameter, every LOB that is
*defined* as being smaller than 16KB, is returned inline and fetched.
