ADF 10.1.3: Simultaneous insert of Master and Multiple detail records

Hi,
I'm trying to implement an Insert page (JSP document) having a Master table form and Multiple detail records grid with a Pop up to insert Detail records into the grid.
The user should be able to input Master record details, then Detail records one by one, and finally insert all into the database.
I'm wondering how this could be done using the Drag n drop feature of ADF (with ADF faces, JSF and Toplink) to the maximum extent.
Please give me a rough guideline on how this could be done.
Thanks in advance

How to create One Master - and 2 detail records region

Hi,
My requirement is to have three regions on a single page, one for master record and two for detail records.
Also, one detail record region needs to upload images (photos) to database.
Can some one tell me how to do this in APEX.
Thanks
Aali

Hi Aali, I have the same issue in a master detail form, I don't know how to upload images in the detail form, can you help me please.
Thanks and regards,

Master with multiple details

(JHeadstart release 10.1.2.) I can make a master with multiple detail pages work (displayed on the same page or different pages), except under one condition. Assume the following situation:
Master: View object A based on entity A
Detail 1: View object B based on entity B with a modified WHERE clause
Detail 2: View object C based on entity B (yes, same entity object as view object B) with a WHERE clause different than the one for view object B
A one-to-many view link exists between view object A and view object B, and another exists between view object A and view object C. The query for each of the view objects is standard (i.e., no expert-mode queries). The master and the two detail view objects (via their respective view links) are assigned to an application module.
I created a JHeadstart application structure file for the application module with Struts and UIX. I added view object A as the top group (table-form layout). I next added view object B as a detail group (form layout, same page) beneath view object A. I finally added view object C as a detail group (form layout, same page) beneath view object A (i.e., parallel to view object B). The module generated and built cleanly.
I ran the application, entered a master record, and saved the data. When I pressed the button to create a new record for detail 1 (view object B), fields appeared for the pages for detail 1 and detail 2 (view object C), not just detail 1. Also, the value of the Descriptor Attribute from the master record that linked it to the two detail pages populated the corresponding field in both of the displayed pages for the detail records.
This behavior does not occur if view object C (detail 2) is based on an entity different than view object B. Will JHeadstart allow a master to have multiple details where the details are based on the same entity object? Thanks.
Ray

Ray,
Unfortunately I cannot reproduce the problem. I filled in the A, B and C using a scott/tiger schema as follows:
A: Departments
B: All employees having a salary < 1000
C: All employees having a salary >= 1000
Then I created an application module with one group having two subgroups everything same page, just like you specified. Everything seemed to work fine. Do you have any idea what's different in your situation.

Examples of Master with multiple details

Hi Leo,
I want to create Master with multiple details
I have been trying for the similar example (Master with multiple details) for long time.
It seems in the following link, you have mentioned that you have done such examples.
Examples/Demos of APEX applications with Master with Multiple Details.
Can you please share the solution to my emaid address [email protected]
Or can anybody help me to get such solution with examples step by step.
I would highly appreciate for any help.
Thanks.

Ok, so here's the rundown.
Create a page with one "master" html region. In that region create your standard text/date/etc. items. Make sure that one of these is a hidden key field that is the key linking the master and details portions. Use a calculation to pre-populate the field from a sequence (or whatever uniqueness generator you choose). It is important to generate this key up front for the processing.
Next I created one report region for each detail table I wanted to link in. Make sure to count the total number of fields you want to work with and that the total is LESS than 50. This is critical. The report should be selecting the columns from APEX_COLLECTIONS for display and manipulation on the screen. It is best to explicitly associate these to the Javascript column numbers now. I used a process to pre-populate my detail entry areas with default values for ease. I also included a button to add a row to each area, but you have to be careful here to use a good combination of form attributes so that the page refreshes don't SUBMIT yet.
Once you have a report region generated from APEX_COLLECTIONS, you have to create the update processes that pull the information from the user modifications into the collection. This is the trickiest part of the whole thing. You have to use the APEX_COLLECTION.UPDATE_ITEM method, and you have to refer to the JavaScript column numbers for the source value and the collection column number for the destination. It is really easy to get these confused - I advise putting this all into a document or on a whiteboard for reference.
Once you have the update processes written (I prefer writing one update process per detail section), write your processes to write the data to the database. Again, I suggest one process for each detail table. Trigger them to fire on submit.
I also suggest creating a debug page to display all of the various collections and to help keep things straight. Once you have one detail area working, it is easier to get the others working.
If you need actual code snippets, let me know and I'll see what I can do.

BC4J: Master with multiple details

Hi,
I have a requirement to display a data form that consists of fields from 3 entities - one master and 2 details. I have view objects for each of the entities.
I was wondering how best to model this:
Should I have one Master VO pointing to 2 different view links (one to each detail VO)?
Or can I have a single view link that models master-multiple-details (not sure how I can do this using the ViewLink wizard)?
Any other approach I should consider?
Thanks,
Niranjan

I don't believe you could create a Master with two details frame using wizard. you need to write/alter some code manually. I did this a lot in my application, but as i mentioned with some manually coding.
here is the general idea:
1- create the view links for master-detail1 and master-detail2 separately.
2- Edit your application module using wizard.
(right click on application module and select Edit Tab). if you did the first step successfully, You should see your master entity and details(as master's children) on left side of wizard frame. Then transfer them to the right side.
3- Create a frame for master-detail1 using wizard.
4- create another frame(dummy frame) for master-detail2 using wizard.
5- copy all codes for detail2 from your dummy frame(step 4) to frame on step 3.
6- Now you need to alter the code in frame on step 3, to locate the detail2 on that frame.
7- Now the dummy frame on step 4 is useless, you can delete it.
Hope this note be clear and help you.

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.

Examples/Demos of APEX applications with Master with Multiple Details.

Trying to get my head round the way to best method/approach to present / allow a user to select / maintain a Master table and then maintain multiple Detail tables that are for the current Master. Typically in my Forms days I would have used tab canvases as placeholders for maintaining the related individual detail table rows. But in the APEX world tabs are used as top level page navigational items. Are there any demos, tutorials or articles on how to implement Master with multiple Details using simple APEX pages with minimal bespoke HTML and Javascript intervention.

Hi Leo,
I have been trying for the similar example (Master with multiple details) for long time.
But i did not get the solution. Can you please share the solution to my emaid address [email protected]

ADF Faces Query Panel: How to display master data in detail table?

Before stating the question, here is the background:
I've a Fusion ADF (model/viewController) app that includes 2 tables with a master-detail relationship. The master table stores error numbers and associated levels of logging severity; the detail table stores the actual message text. These need to be separate, related tables because the requirement is that message text for a given error number can vary by product release.
Messages are added in a bounded task flow; data for the master table entered in 1 fragment, data for the detail table in a 2nd page fragment. In the app, the Entity Objects for these tables are related with a foreign key association and have a composition association. This was done because the error numbers are generated in an Oracle DB sequence, and from what i have read that is a way in a task flow to have ADF put the number generated for the master table into the related key of the child table.
The question is this:
I need to create an ADF query panel with a table that searches on the detail DB table. However, i also need to use a couple of fields from the master DB table in both the query and in the ADF table. In addition, I need to add the ability for the user to edit either the master or detail record for the row he/she selects in the ADF table. I know how to create a view that would display the info i need; however, i have not been able to figure out how to obtain the keys for the selected ADF table row and pass them to the task flows that would edit.
The master table has a numeric primary key. The detail table primary key consists of a foreign key to the master key and also a release number.
I'm new to ADF and have been struggling with how to do this: i've a workaround that is functional but too klunky to be a permanent solution. So, could someone point me to some information on how to accomplish this?
Versions: JDeveloper 11.1.1.4, ADF Business Components 11.1.1.59.23
Thanks for your help!

Thanks. I tried this out, but ran into an issue in that the detail table has 2 keys - a foreign key to the master primary key, and a 2nd key that uniquely distinguishes the detail. So i tried various things centered around using the SetCurrentRowWithKey operation and trying to obtain the selected ADF table row using an EL OF #{data.<pageDef>.<Iterator>.currentRowKeyString}; however i could not get the detail record for the selected row to display.
I did find another approach that worked - I am wondering, is there anything problematic with this approach?:
1. Create a VO joining the Master and Detail tables, with the Detail table being updatable.
2. Made sure the applicable attributes were defined as keys.
3. Add a query panel w/table using this VO.
4. Create an ADF form based on the VO, showing the updatable fields.
5. Create a bounded task flow with the following set on the Behavior tab:
a. Share data controls with calling task flow
b. Always Begin Transaction
I specifically am wondering whether "Share data controls with calling task flow" has any negative implications or gotchas to handle. The doc at http://download.oracle.com/docs/cd/E21764_01/web.1111/b31974/taskflows_parameters.htm#ADFFD1693 doesn't suggest so, but just wanted to double-check before I go down this path.

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

Master Detail module returns to Master page after Detail record saved

Using Oracle Designer Editor version 10.1.2.0.2 I have generated a Web PL/SQL package
set up as a Master/Detail where the Master and Detail records appear in separate windows.
The Master window contains multi-records each with a link to the related Detail records.
The user clicks on the Detail link and the window that appears will allow the user to insert
a new Detail record. Once the user clicks the Save button I need the Detail window to disappear
and the focus returned to the Master records preferably after a new query is performed.
What are the steps I need to perform to navigate back to the Master page and close the Detail
page?
Thanks,
Mark

The simple answer is that to do exactly what you want would take some fundamental changes to the way the framework works. The actionInsert procedure does what it does - it saves the changes and redisplays the form. You can do post-generation changes to make it do something else, like return to the Master, but I'd advise against it.
But if you want a way to return to the Master window, where the user clicks a button or link on the detail form after saving changes, that we can do. Just make a note of the URL that does the initial display of the Master page - probably my_module_name$.startup. Go into the detail module component, and click the User Text tab. Then at Text Location, "Bottom of View Form" (or Top if you want the link there) add for a link:
htf.anchor('my_module_name$.startup','Return to Master')Or for a button:
htf.formOpen('my_module_name$.startup','GET')||htf.formsubmit('Return to Master')||htf.formCloseYou may need to set the SECECS preference for this module to "No" to get this to work.
An alternative to my method is to define an Action Item in the module that does a navigation. I often am linking directly to the View form for a master table, rather than a record list, as you are, and Action Items don't work well for that, but one might work fine for you.

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

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.

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.

I hope you make some suggestions on how to realize it?
Thanks

OK Shiladitya
Thanks for your info...I'm now trying to link from the master table to 5 MDforms with the same master but occulting all the fields except the name....any suggestions?
My principal goal is howto call (from the links) with the actual master record...it is urgent....help will be very appreciate

Nested af:tables - master with multiple details

All,
I would lilke to have an af:table which has several columns, more than one of which contain a detail data af:table. I would like to be able to update the data in these af:tables.
I have succeeded in doing this when there is only one detail table within the master table. The technique involves creating a tree binding, make the master use the treeModel as its value, and make the child table use row.children as its value. But the tree binding only can have one child per parent node, right?
So I am looking for other ways to do this. I was wondering if a variant of Steve Muench's technique which he shows in his example #71 would be a starting point for at least getting the data displayed. This example shows how to put detail data into a drop-down list in a table. What steps would be needed to make the data return in a row set or a collection or whatever form a af:table component could deal with?
I hope my question makes sense. This topic is very important to me if anybody has any ideas.
Michael F.

Interested question; one I do not know the answer to at the moment, I am afraid. I would like to know your results.
To tell others, though, what I have done. I did finally adapt Muench's not-yet-published examples #71 to work with a table. Here the table has as it's value "#{backing_app_EPG_DAYPG.jobDayDriverTable[row.Id1]}"
This accesses a hash map defined in the backing bean as follows:
public Map jobDayDriverTable = new HashMap(){
@Override
public Object get(Object key) {
Number jobDayId = (Number)key;
if (getEpgDayPage().jobDayDrivers(jobDayId) != null) {
return getEpgDayPage().jobDayDrivers(jobDayId).getAllRowsInRange();
else return null;
jobDayDrivers returns RowIterator. From this I call getAllRowsInRange which returns a Row[]. The table consumes this as a value, and lists the values as I want.
Since the table is using Rows for its rows, I am guessing that it would have access to #{row.rowKeyStr}, or at least #{row.<pk>} which would allow you to programmatically set the current row using code like the following:
public static boolean setCurrentRow() {
// BindingContainer bindings = getBindings();
OperationBinding operationBinding =
// bindings.getOperationBinding("setCurrentRowWithKey");
(OperationBinding)EL.get("#{bindings.setCurrentRowWithKey}");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return false;
return true;
You could call this as part of code in a pages backing bean behind a button or link.
Hope this helps somebody.
By the way example #71 was to get a detail set of rows from a master row value and display the detail set in the master row of an af:table.
