>>>I'm still investigating... the source of my problems may be the weird behavior in cases when there are two adapters on the same base table, and one of them gets requeried (by either .cursorRefresh(), requery() or refresh()) - first time it may work, second time it seems the cursor of the other one gets closed. Or something like that, still haven't gathered all the evidence.

>>We have at least one app with some tables where up to slightly more than half a dozen ca query into one table and CursorRefresh() depending on user input - mostly as rowsources for dynamically filled dropdown lists depending on other parts of the program. Do not remember that something special needed to be done, but was using fwk classes - possible some magic was done there, but I doubt it. RO access, but I doubt that could be your problem.

>The scenario I have is that one CA creates the record, the next bizobject adds a few records into a child table and then writes the FK to it into the 2nd CA on the same table as the first one. Then a third CA on the same table is fired and just retrieves the same record. At that point, it misbehaves. Mostly (depending on what I do) it thinks that it got a record inserted into the cursor (even though that record is retrieved from the server) and does an automatic tableupdate() which generates an insert statement being sent to the SQL right away.

Backend you were working against? .WhereType you are using ? Which PK-Type and (depending on previous answers) how created ?
