Should it? Have you defined an AfterFetchRow handler in your app?
There is none by default AFAICT.


If you open IBF_DataPump.pas (open IBF_Base.pas first to avoid errors)
and set csDst (the destination cursor) so that CheckRequired=false,
then you should be able to proceed. In my testing the insert
parameters are being set appropriately if we just tell the destination
not to check whether the fields are assigned before trying to post.


I am not certain why this should be different from IBO3 to IBO4. Its
either something in the timing or something different in the
column-buffer handling that is making it so that IBO4 is not seeing
the redirection of the column-buffers to the source row. (The pump is
setup to cheat, so that the destination is actually posting directly
from the source row.)

I think we may have to wait for Jason's input to get a real
explanation - and to say whether the above "fix" will be OK for the
long term or whether he can work out something better.
