Adding Multiple Records with Express

Question

Hello All,
We have a CRUD application written in Express 2.0 that allows users to
enter part numbers and associated information. Our part numbers are
structured as a prefix, alpha, suffix and 'M' or 'P' number variations :
1 AB 2 P3 for example. We have provided functionality to allow the
user to enter multiple P or M variations all at once, say 1 AB 2 P1 thru
P100,
using a dialog box where they enter the starting number, ending number
and step.
The problem comes in the AddRecordsToSave method.
This method correctly builds the array of BusinessClass needed to be
passed to the Save method, however, the Save method adds only the
initial record (the one from the original Express data entry screen)
to the database.
I have traced the problem to the BusinessClient.Update method called
from
Save. I believe I am missing some query information that should be
built into
AddRecordsToSave, but I am completely unsure of how to provide this.
As you can see in the attached code, we are using the LogAttr method to
post
changes. Apparently this is not enough. What am I missing here?
The InstanceStatus key of the added records is set to ST_EMPTY by
default....
I have tried forcing this to ST_UPDATE, only to receive an error that it
should
be ST_EMPTY......?? I am confused. If anyone can shed some light on this
for me,
I would appreciate it. Thanks for any help.

Hi There,
If attr is not specified in your LogAttr() call, the
BusinessClass
will be put in the update state but not attributes will
be logged.
That may be the reason why only the displayed record(
fetched from
the DB ) is getting logged, but not the new records.
I think you should use ATTR_SIMPLE with LogAttr. This
will cause
all the attributes to be logged and a proper query to
be built
to insert the newly created record. I am no Express
Guru,
but it works fine for me. Also, try not to modify
InstanceStatus directly.
Sometimes it might lead to inconsistencies. The online
help
The Add Records to Save example really helps.
Good luck!
