Hi Brad,
I was thinking along the same lines - just trying to avoid having to
re-write all my pages and code.
I'll do an experiment and let the list know what happens.
Thanks for the response.
Michael.

Michael,
I'm just guessing here, but in Active4D v4 I believe there is a new
feature where you can now use 4D process variables in your Active4D
code without first declaring them in 4D.
Maybe what you are seeing is a side-affect of this?
What happens if you don't declare the variables in question in 4D?

Hi all,
I have a database that I've just converted from Active4D v3.x. and
4D 6.8 to Active4D v4 rc6 and 4D 2004.4.
Everything works AOK except for the following line of code:
vTotalStaffRequired:=$SumRequired-aSplitTotals{6}
vTotalStaffRequired is typed in the database as a longint and
is initialised in the A4D script via a call to a 4D Method.
$SumRequired is also typed as a longint and is assigned within
the A4D Script
aSplitTotals{6} is a Longint array and is assigned in the
script by a 4D Method call
Whilst I can do the following:
vTotalStaffRequired:=$SumRequired
vTotalStaffRequired:= aSplitTotals{6}
if I try to do vTotalStaffRequired:=$SumRequired-aSplitTotals{6}
I get the following error: "Cannot change the type of a 4D
variable in a compiled database"
The following lines of code all return the value 9 (i.e. type
Longint)
write to console('vTotalStaffRequired=`type
(vTotalStaffRequired)`')
write to console('SumRequired=`type($SumRequired)`')
write to console('aSplitTotals{$Role}=`type(aSplitTotals
{$Role})`')
so vTotalStaffRequired is definately being seen as a longint.
In fact if I do,
vTotalStaffRequired :=10
the assignment happens without a problem.
So it appears I cannot assign anything to vTotalStaffRequired if
the value being assigned to it is in the form of a variable.
Anyone any idea what is going on here?
Regards, Michael.
