Having trouble with SQL Dataserver and buffer updates via the progress triggers.

[okion]

Hi there,
Does anyone knows how progress handles buffers updates via the progress triggers when there is a SQL dataserver?
Progress is sometimes confused when buffer updates are done via the trigger for different tables.
When I update the trigger buffer and also another buffer and release that other buffer the old buffer value is not the old value anymore
IE:
Initial situation:
Table Order:
Order.cdstatus = 'O':U.
Order.cdproces = '':U.
Table OrderLine
OrderLine.cdstatus = 'B':U.
OrderLine.cdproces = '':U.
Now we run the following code:
ASSIGN OrderLine.cdstatus = 'O':U.
RELEASE OrderLine.
The releases calls the OrderLine trigger:
There we do:
assign OrderLine.cdstatus = caps(OrderLine.cdstatus).

/* B -> O */
IF OrderLine.cdstatus <> o-OrderLine.cdstatus THEN DO:
FIND order ... EXCLUSIVE-LOCK NO_ERROR.
IF AVALAIBLE order THEN DO:
ASSIGN Order.cdstatus = ?
Order.cdproces = "XXXX"
.
RELEASE Order NO-error.
END.
END.

In the Order trigger i put a message:
MESSAGE 'TRIG Order BEGIN o-Order.cdstatus ' o-Order.cdstatus ' Order.cdstatus ' Order.cdstatus.
Now we get the message:
o-Order.cdstatus = ?
I should expect that the old value should be 'O'.
The weird part is that when I remove the
assign OrderLine.cdstatus = caps(OrderLine.cdstatus).
line it works fine.
An solution is also when I re-order the assignment of the order fields.
ASSIGN Order.cdproces = "XXXX"
Order.cdstatus = ?
.
I did not expect that an assign of the trigger buffer(OrderLine) can influence another table buffer (Order).
Does anyone knows what the reason is of this behavior.
