Hi list

I'm getting an access violation error when I'm selecting a value from
TIB_lookupEnh (before OnCloseUp event fires).

the main IB_query has fields Towar_ID and Towar (the secon one is set
computed since it comes from subquery)
the lookup IB_query has two fields Towar_ID and Nazwa
with KeyLinks set to TOWAR_ID=TOWAR_ID
and KeyDescLinks set to NAZWA=TOWAR

Any idea where this error comes from
(it looks like there is not IB_Session object available in
TIB_Dataset.EndCallbackFreeze procedure)

Delphi 5, IBO 4.2Eb, EnhComp 2.06

TIA
Marcin
