RE: Java Server Faces Relational Record List -- WDSCI-L

Robert,
I agree with your statement for an update of a record.  I do need something
unique. 

Here is some more information about the issue.  In the JSF tutorial I found
in WSAD, the record list control gave me the entire record contents.  From
that record, I passed the unique key to an update JSP.  The update JSP used
the unique key to get the record for update purposes.  

If I can update records from my list of records JSP, I would need a unique
key.  I think I should have a choice on whether my JSP will be used for
update or not.

I'm not from IBM, but I can venture a guess as to what's going on behind the
scenes.  The tooling probably wants a unique key in case you would want to
perform updates on it.  If you update one of the ten records, how will it
look up the record to update?  It would expect you to tell it which fields
uniquely identify each record.

Dear IBM,

Help me see the light.

Maybe it's just that I am a RPG programmer trying to figure out Java.  

Assuming FILEA has 10 records for customer number 5, when I run this
statement SELECT * FROM FILEA WHERE CSTNUM = 5 I should get 10 records.

When I run this statement using a relation record list in JSF, I get 1
record.

This is what I found to get around my problem with the relational record
list control in JSF. The relational record list is fetching only the unique
values from the table.  Example: If I want all the records that match a
customer number, I have to define a 2 part unique key to get the entire
list. 

Through the relational record list wizard I have to define my primary key to
the file as being customer number and invoice number to get the previous SQL
statement to return all the records instead of just one.

What in Tarnation is going on?

Can anyone at IBM explain this to me?

Some more detail. 
When I run the SQL statement through the data perspective, I get the same
six records. Also, I am connecting to an iSeries using jt400.jar

Hello all,
I'm trying to build a sample app using Java Server Faces.  I am trying to
use a relational record list.  After completing the wizard to tie the
relational record list to a database, I run it on the server and only get
one record when I am expecting 6.

Here are the details
Using WDSc 5.1.2
Using WebSphere v5.1 Test environment

The SQL statement listed in the console looks like this.

SELECT LIB.PGMDOCPF.PDTYPCDE, LIB.PGMDOCPF.PDNAME, LIB.PGMDOCPF.PDLIB,
LIB.PGMDOCPF.PDUNIQUE, LIB.PGMDOCPF.PDCODE, LIB.PGMDOCPF.PDSEQ,
LIB.PGMDOCPF.PDINFO FROM LIB.PGMDOCPF WHERE ( PDTYPCDE = '*PROC' AND
PDUNIQUE = 1 AND PDCODE = 'NAME') ORDER BY PDLIB ASC, PDNAME ASC

The SQL statement looks legit.  When I modify the SQL statement to allow for
a larger record set, it comes back with the first instance of each unique
PDTYPCDE and PDCODE combination.

What am I overlooking?  Is there some setting that limits the list to the
first instance of each record with the keys I'm looking for?

Has anyone come across this issue?
