ADF BC - One Master and Two Detail pages How To?

I have an existing ADF BC .jspx master-detail page that works fine. It shows one product as the master (read-only; no navigation controls) and assocatied customer feedback as the detail (multiple records; read-only.) Now I also want to compute some averages from the same table used to create the detail view object. I have created a second view object because this requires a separate query that calculates aggregate values. I want to take advantage of using view links so that this 2nd view object is automatically linked to the master record via the primary key.
My question is how can I link this into the existing master-detail data control so that I can drag/drop it to include id on the existing .jspx page and the primary key linkages will be handled automatically?
Tables
Product
Feedback
View Objects
ProductView
FeedbackView
FeedbackAVGView
Current ViewLink
ProductFeedbackViewLink = ProductView + FeedbackView
Current DataControl
ProductFeedbackViewLink-Instance
Data Control is displayed on .jspx page; want to also include 3rd View Object, FeedbackAVGView, in the Master-Detail relationship and display on the .jspx page

Thanks for the reply. The existing customer feedback view object displays the customer's text feedback (testimonials) - these will be displayed in a read-only table with multiple records.
The new view object aggregates the ratings score from the customer feedback (same FEEDBACK database table) and will use a form to display the results (not multiple rows.) The PK is included in the aggregate view object query.
Note there is already an existing viewlink between the PK (Master) and FK (Feedback) - in the data control, this viewlink is an instance of the Master View Object and the Customer Feedback View object. Now that I have created a third view object, should I create another View Link between the Master View Object and the Customer Feedback AVERAGES View Object? If I do this, how do I include it in the existing .jspx page? If I add this new View Link to the Application Module I will have two different Data Controls:
Data Control #1: Master (Product) View Object + Customer Feedback View Object #1 (implemented as a master-detail read-only form/table on a .jspx page)
Data Control #2: Master (Product) View Object + Customer Feedback AVG View Object #2
I'm confused as to how to integrate the second customer feedback view object into the existing Data Control / Master-Detail read-only form/table on my .jspx page?
thanks

I want a JClient Form with one mater and two details

Hi,
In my JClient Form, I want to have one master view and TWO detail views. The two detail views are linked to the master view simultaniously. Can Jdeveloper do that?
and How?
Stephen

Sure. Just define the VO's and the relations between them and afterwards develop some independant panels which describe the VO's. You can then place each panel on a single panel and organize them the way you want.
However, there isn't a way to simply generate the entire deal with a single wizard. You will have to run the wizard multiple times for each of the panels you wish to create and then manually put them together.
Hope This Helps

Hi,
You do not need to mount a screen. Just add a new region with several text fields inside. You should fetch a row by a process and populate the set when you load the page or click on a button. Insert, update, and delete should be done by processes. You have to have Next and Previous buttons to brows trough all rows of the detail table.
The most important thing here is what the connections between tables in your database are.
If they are the "One to many, One to one" you can use the approach described above.
If they are "One to many, One to many" will be better to use buttons or links to lunch details' tables in separate forms.
If the second and third tables are connected only to the master table you can use two buttons at the right of every master row. Clicking on the buttons will bring separate form for each detail table.
If the third table is just a luckup table to the second one you can use "Select List" field into tabular form of the second table in one Master-Detail form.

Two Master and two details block problem

Hi,
I am getting problem in displaying the correct records on one of the detail block. There is one main master block 'A' and then it has one details block 'B' and then this detial block 'B' has got two details blocks 'c' and 'D'. I form different queries based on the value selected at detail block 'D'. Now i go to ,aster block and execute_query then it fetche the correct record at master block not on detail block 'D'. I have one anmoly in Dtails Block D and Master block B that they are joined with a common field not on the basis of proimary key and forign key. Please sugget

Hi,
When you establish the relations using the references, then oracle will look for the parent key in both the parent tables. Either you need to remove the foreign keys or change your db design to add one more table and have one-one parent child relationships.

We have one computer and two users. How do we get itunes to keep our apps separate for our iphones 3gs?

I'm new to iphones and Apple in general. I'm not tech savvy at all. My husband and I just got the iphone 3gs (separate phones). Itunes wants to put the same apps on both phones (one computer). Can we stop this? We don't want the same apps on our phones. Thanks.

Instead of syncing all apps just select the ones you want on your device. I am assuming your using the same apple ID. Just plug in phone select it from the left side of itunes then select the apps tab and uncheck the apps you dont want. Itunes will remember settings for each device.

Master with two details(child) relation?

Hi guys,
I 'd like to have a Form with one master table and two detail tables.
The business component wizard doesn't allow
me to create this relation.
Although these two details table are logically children of the master but have not defined specifically Foreign key for them on table/database level.
I created Associations via JDev3.1 to join
these master with details, but still business
component wizard didn't allow me to have
one master and two details.
Do i have to create foreign keys to join children to master on database level or
I can create an association with JDev? How?
Thx
Ali

You could use "New"/"BC" and create a ViewLink with the same name as the FK Assoc. If you edit the PackageModule, you should be able to see your FK link in there.

Displaying a Master with two detail view objects

Hi,
I have a situation where I need to relate a Master view object to two Detail view objects. Currently I am doing the lookup manually (using viewcriteria!) but I would much rather have the framework handle this. Does anyone know of a way to A: Link two details to one master and B: Display them on the same page.
I am using Jdeveloper 9.0.3.3 (1205) and currently have a straight BC4J/JSP application with no struts or UIX.
Thank you in advance for any help you can provide

If I understand you correctly. You should just have to create two separate viewLinks. Add the datasource tags for the master and the two views via the viewlinks. Then use a rowKey to get the correct master.
Hope that helps!

Is this possible to achieve?
If not Please advise how I can use another way to display the data with Master - Details 1 & Details 2

Creating a Master with Two Detail report style

In a Group-Above report data model, how does one add a 2nd detail group appearing at the same hierarchial level as the 1st group?
The report already exists with MASTER and detailA. I need to add detailB and tie it to MASTER just like detailA.
|MASTER|
|detailA||detailB|
\-------/\-------/

Amjad,
Thanks for the reply. My question relates to your suggestion #1: How does one create detailB in the data model?
The only thing I have been able to do is to create a 2nd query linked to the 1st query. This makes the data model look like it has two masters each with one detail. What I want is a single MASTER with two details.
Are you suggesting that the only way to accomplish this is by having two queries, one linked to the other, as in the crude rendering shown below?
|MASTER1||MASTER2|
|DETAIL1||DETAIL2|
The above would be displayed in the data model as follows:
|__Q_1___||__Q_2___|
|G_DETAIL1||G_DETAIL2|

How to create a JClient form with one master block & multiple detail block?

Hello,
I am using Jdevelopver 10.1.2
I want to have a JClient Form with one master table A and two detail tables B, C.
But in the JClient Form wizard, I can only create a one master with one detail relationship. Can I create multiple details in that wizard ?
Thanks

Create a JPanel based on the second detail table with the wizard and add manually the JPanel to the Master-detail Form.

In my family we have 3IPhones 4S, one IPhone5, one IPad3, one IPadMini and two IPad 4. Is it possible to use the same energieadapter for all of those ?

Yes but the iPhone chargers will struggle to charge the iPads ,they need more power than the iPhone chargers produce and with an iPad will charge VERY slowly
The iPad chargers whether 10w or 12 will happily charge all your devices and Apple confirms the compatibility on the relevant web page.

Master with multiple details page, is there an example out there?

Many hints and suggestions can be found on this forum about building a page with a master with multiple details page. But is there a working example somewhere? It looks quite complicated to me.
Also I would like to know if it is because of my Oracle Forms background that I miss the possibility of building this kind of forms in application express. Are there other ways to setup the pages so that you can do without them?
thanks Rene

Let me elaborate on my requirements a bit:
The form I want to create should look like this:
Master
Atrtibute_1
Attribute_2
Attribute_3
Attribute_4
Details_1 Add Delete
[] item1 (read-only)
[] item2 (read only)
Details_2 Add Delete
[] item1 (read-only)
[] item2 (read only)
So basically it should be possible to maintain several lists of items that belong to the master record. Checkboxes allow the user to select records for deletion. The Add button shows a pop-up window that lets the user select an item to add.
