IBO 4.2Ib, BCB5, FB1.03

Discovered another "feature".

In AfterFetchRow event I wanted to check the value of ACCOUNT field in source ARow. The value of this field was NULL, but in the DataPump->DstRow (destination) this field had correct value.
All other fields in ARow showed their values correctly.

I can't figure out the logic behind this bizarre behaviour. How can the source be NULL, but destination contain correct answer? How can one source field be NULL, but all others contain values?
