TOracleDataSet and BLOB problem

[giga]

Hi! Can you help me? I have table E_FP_STAV with BLOB column FPSTAV_ELPODPIS. I am create TOracleDadataset X with SQL: select X.RowId, X.* from E_FP_STAV X where ID = 1

X.EDIT
X.FieldByName('E_FP_STAV').Value := 'Hello';
X.POST

On X.Post application raised exception class EOracleError with message ''

What is wrong?

OracleMonitor log:

select * from E_FP_STAV where rowid = :doa__rowid  for update nowait

LOB.Write(5)

update E_FP_STAV  set FPSTAV_ELPODPIS = :v11  where rowid = :doa__rowid  returning rowid into :doa__rowid
