Multi-row editable Detail Component on the same Page as Master (WSG)

Hello. There was a trick to place editable (with Update button and Delete? checkboxes) Detail Component on the same Page as Master. Something about a Creation of Detail Component in Property Palette Mode (against of Dialog). Can anyone point me please to those hint?
great thanks,
Wit.

Look at the page branches. There will be one or more which goes to the first page. Change it to go to the current page instead of the first page.

Can i use one JSF component's value for other component in the same page.

Can i use one JSF component's value for other component in the same page.
For example
I have a <h:selectBooleanCheckbox id="myChk"> in my jsf page, i want to access its value for another component like:
<h:commandButton disabled="#{myChk.checked}" action="myAction" value="myValue" />
** "myChk.checked" >> I am just asuming "checked" property is available...

Bind the checkbox to a UIInput myChk property. Then you can reference this property from the page, e.g.
<h:selectBooleanCheckbox binding="#{myBean.myChk}" onchange="submit();" />
<h:commandButton disabled="#{myBean.myChk.value}" action="myAction" value="myValue" />

JSF multi row editable detail form -- moving backwards or forward

Innocently trying to create an intuitive editable master detail JSF form. Similar to what you would want in any application and something that can be done in less than a minute in Oracle Forms
The master form is a just a simple editable single master form based on the dept table. and the detail is the emp table. I have create the model using the wizard and made sure a link view is created.
The details form is a multirow form with all the editable columns
I added two button for the details form (create, remove)
I entered the master record (no commit yet)
then i moved the cursor to the details form and created a few records, i found an error in the second row in the detail form, therefore, innocently, i selected that row and pushed the Remove button. shocked to find out that the first row in the details form is deleted regardless of which row is selected. Additionally, when a row is created using the create button, the row is created above the first row of the details form (as if the first row in the details form is always current).
Such requirement should be easily satisified by a Framework?

thank you frank for your response
Actually, my DETAILS form DOES include the Select Option, and i was really expecting (and accepting) the fact that i need to point to the row i need to delete. Actually, 20 years back i was 8080 assembly language programmer, and used to handle thing at very very low level. However, i do select a row, and i can see the Radio activated for that row, unfortunately though, the seemingly selected item in the DETAILS form is not the one that is removed, it is instead, the first row that is actually removed. It seems as if the form rows are not synchronized with the ROW selector you mentioned,, The first row is somehow internally selected (always)
This is the interesting part.
I created another project with a single multi row editable table (without master details) only a master, and guess what, it is working beautifully! exactly as you descirbed. Select a row, press delete and there you go, the record no longer exists

Master Detail Reports on the same page

hi experts. i need your assistance in one issue...
i have a master detail reports in one page. Master report displays all the products and details report shows their orders...
what i want is, when user clicks on products graph its detail graph show the orders of that particular record on the same page. Both reports would remain visible on the same page side by side.
if anyone can help?

Hi Asif48,
Just as Visakh suggest, we can add the master data and subreport in the same tablix, then set the visbility of subreport to toggle based on click action of master level row. And add some parameters to filter the related data based on the master report field.
For more details, please refer to the following steps:
Create another report as the subreport and insert some fields.
Create a parameter named Order in the subreport.
In the main report, right-click to insert a subreport in the column right of the master tablix.
Right-click the subpeort to open the Subreport Properties, and select the subreport name in the drop-down list.
In the left panel of the Subreport Properties dialog box, click Visibility.
Select Hide option, and select Product (master level row) to display the subreport to be toggled by the Product report item.
In the left panel of the Subreport Properties dialog box, click Parameters.
Select Order in the drop-down list of Name, and select [Product] (use the related filed name) in the drop-down list of Value.
If there are any other questions, please feel free to let me know.
Thanks,

Unable to open the detail report in the same page/window

When i use the "Navigate to Web Page" action link to navigate to the detail report, the detail report is opening in new window. Is there any way that the detail report can be opened in the same page/window.

Hi,
why don't you use the master/detail table option when dragging the master VO ?

Multiple details table on the same page

Newbi to APEX. Can I have muliple details table for update/insert in tabular format on the same page with the same master? Thanks!

In the meantime, I can answer to your questions:
· Why does JHeadstart not make use of the UIX-Struts integration (see Chapter 15 of the UIX developers Guide)?This has been done to allow the same page to be run both with Struts and MVC Framework, without needing to change the page. Using the UIX-Struts integration would have made the pages 'controller aware'.
· How do you specify which columns/attributes in a Table Layout are sortable?As far as generation is concerned, you can only specify the whole table to be sortable. In case of UIX you can post-gen modify the <sortableHeader> tag of each column separately. In case of JSP you can remove the <a href> tag for each column that you do not want to sort on.

Master and detail in the same page

db11xe , apex 4.0 , firefox 24 ,
hi all ,
i am trying to insert the master and detail data in one step in the same page :
i have two tables (clients) and (tests_administered)
the client table's region contains theses items
client_id
client_name
the other table's region contains these columns -- the tabular region
row selector
test_admin_id -- pk, hidden
client_id -- hidden , this is the one i should populate with values
and more columns
i've done this :
1- removed the condition of the tabular region .
2- Added the request CREATE to the list in condition of the APPLYMRU process -- or :request like ('CREATE')
3- Added new process with following code : -- with sequence before the applymru process and after process row of clients process
for i in 1..apex_application.g_f02.count
loop
apex_application.g_f02(i) := :p2_client_id ;
end loop ;
but nothing happened . why ? what did i miss ?
thanks

Hi,
Create a Master Detail Form through the APEX Wizard
Make sure you choose the Primary Keys for the Master Detail as one of your Column and not the ROW ID.
Selecting an existing Sequence for the Primary Key is preferred.
Select the option the where your Master and Detail appears in the same page.
Initially when you run the page your master and detail will not appear at the same time in the page when your Master Detail Form is in the entry form mode. For this you have to go to your Tabular Form(Detail Form) region, and below you will have to remove the Condition for the display of your Tabular form and set it to “No Condition”.
Now when you run the page both the Master and Detail form will appear together in the create mode but you will not be able to insert or create both master and detail records at the same time when u click the create button. For this the following needs to be done: You need to create a PL SQL Tabular Form process :
Let's say your master form is based on DEPT and your detail tabular form is based on EMP. Make sure the following things are configured:
The DEPT insert/update DML process runs before the new tabular form PLSQL process. (ie) the new PL SQL Tabular Form Process that you create should be inbetween Automatic Row Processing(DML) and Multi Row Update Process , so create the new Tabular Form Pl SQL process with a sequence number inbetween these two Processes.
Make sure you choose Tabular form while creating this PL SQL process.
The new tabular form PL/SQL process executes the following as the source
:DEPTNO := :P1_DEPTNO;
Where DEPTNO is the Foreign Key column in the Tabular Form that links the Primary Key Item P1_DEPTNO of the Master Form.
Finally this new PL SQL process conditionally runs when DEPTNO is null, so you need to add the following condition to the process:
The final step to accomplish in creating both the Master and Detail records at the same time is to make a change in the condition of the Multi Row Update Process. :request in ('SAVE','CREATE') or :request like 'GET_NEXT%' or :request like 'GET_PREV%'
-We make this change so that records get inserted into the Detail table when we click the ‘’Create” button.
Now you can Run your page and create both the Master and Detail records at the same time.
Thanks and Regards,
Madonna

Keeping heading and detail on the same page

Hi, I have a report with a group header section and a detail section. How can I keep the heading section and all the detail section on the same page without starting each group on a new page?
The detail section will have either 2 or 3 records with some of the objects set to grow if the data doesn't fit on one line. This results in several changes of group appearing on the same page which is what I want. However, what I don't want is the header section on one page with the detail section on the next, or the header and some of the detail records on one page with the rest of the detail records on the next. What I would like is the report to start a new page if the header and all the detail records don't fit on the same page but without starting a new page for every group change. How can I achieve this?

you can put the group header and details into a sub report on the old group header section.
then hide the details section

Master Detail on the same page PHP - MySQL

Hi,
Is it possible to create a page using spry master region and call MySQL data into a Spry detail region, like you do with xml data?
Basically, is there a way to have master detail regions on the same page without using frames?
Thanks
Bert

Thanks for that, very useful indeed.
But isn't it going to be slow, first transferring the MySQL data to XML then reading XML to display the records.
What is the advantage other then displaying master detail on the same page?
Thanks

Show master and detail viewobjects in the same jsp

I have two viewobjects which have a master-detail relationship (a viewlink between them).
What I want to do is to show both the master and the detail data in the same jsp, i.e for every row in the master viewobject I want to show all the rows in the detail viewobject.
I tried to drop the master vo on the page from the component palette and then the detail vo next to the master vo, but then only the first row in the detail vo is shown on the page. I want all of them to be shown.
Can anyone please point me in the right direction here?
Ps: I'm using JDeveloper version 9.0.5.2
Thanx a lot
Tom

I dropped both viewobjects as read-only tables and they both have the rangesize set to -1.
I think I made myself a bit unclear when asking my question. I do not want a "normal" master-detail view in my jsp where you see one masterrow and all the detailrows. I want my page to show all the masterrows with all their corresponding detail rows listed under the master row.
The pseudocode may look like this:
for each row in MasterViewObject loop
<<display data in MasterViewObject>>
for each row in DetailViewObject loop
<<display data in DetailViewObject>>
end inner loop
end outer loop
As you see I have a double loop here. Is somehing like this possible without "manually" doing all the stuff?
Thanx
Tom

To create an application with a master and two details in the same page

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.

Multi row edit without having to use htmldb field

Hi guys,
a question: have someone ever implemented a multi-row edit report, like the one on Oracle HTML DB Handbook, without having to use htmldb field?
If so how? Only describe the steps or provide me some links. I think is enough.
Other little question:
When you use the syntax like:
htmldb_application.g_f05(i) (inside a for loop), can i use another naming style instead of using gf05 ?
Let's assume that g_f05 is sal, for me would me more clear use a synthax like htmldb_application.sal(i).
I think would be a good improvement in the future version of APEX.
I
thank you very much

hey,
i think that what i saw in the sample application / section admin can't work for my needs, such i'have a quite complex query (pl/sql f body ret sqlquery).(infact the demo is based on a simple query, while i need to use a psqlf.b.r.q)
However what i need is only a row selector, using a report based on a psqlf.b.r.q.
By me i've to use the htmldb_item.
Maybe for my purpose a collection can simplify the problems, however this is briefly what i'm trying to do:
I've 2 set of data.
D1 and D2.
D1 is based on complex filter(which i think it can't be managed from a normal query at all / you have to use pfbrq)
D2 is not(quite simple).
D1 AND D2 have the same type and nr of columns.
The user can choose from a radio group this 3 mode of view.
1 - The user see D1 (UNCHECKED) UNION D2 (CHECKED).
2 - The user see only D2. CHECKED.
3 - The user see only D1 UNCHECKED.
Both D1/D2 can be displayed in the same report.
If Data of D1 are already in D2 they are checked.
(i think here a not in select can do quite well the job).
Hope that somebody understand what i've tried to explain, or maybe has had the same type of problem.
Thank's a lot

Multiple (updatable) details in the same page.

Hello,
I tried to put two updatable details in the same page and got the error
"Updatable SQL Query already exists on page 11. You can only add one updatable SQL query per page. Select a different page"
So having more than one updatable detail is not allowed in apex ?
I have a master table with three details. Should I create one page for each one of them ?
Thanks in advance
Bye
Nicola

What you want to use are called collections. Here is a simple collection example:
The process goes in 4 steps: gather the data, display the data, update based on user input, then write the changes. Each step requires it's own piece of code, but you can extend this out as far as you want. I have a complex form that has no less than a master table and 4 children I write to based on user input, so this can get as complex as you need. Let me know if anything doesn't make sense.
First, create the basic dataset you are going to work with. This usually includes existing data + empty rows for input. Create a Procedure that fires BEFORE HEADER or AFTER HEADER but definitely BEFORE the first region.
DECLARE
v_id     NUMBER;
var1     NUMBER;
var2     NUMBER;
var3     VARCHAR2(10);
var4     VARCHAR2(8);
cursor c_prepop is
select KEY, col1, col2, col3, to_char(col4,'MMDDYYYY')
    from table1
    where ...;
i         NUMBER;
cntr      NUMBER := 5; --sets the number of blank rows
BEGIN
OPEN c_prepop;
    LOOP
      FETCH c_prepop into v_id, var1, var2, var3, var4;
      EXIT WHEN c_prepop%NOTFOUND;
        APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => v_id, --Primary Key
        p_c002 => var1, --Number placeholder
        p_c003 => var2, --Number placeholder
        p_c004 => var3, --text placeholder
        p_c005 => var4 --Date placeholder
    END LOOP;
CLOSE c_prepop;
for i in 1..cntr loop
    APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => 0, --designates this as a new record
        p_c002 => 0, --Number placeholder
        p_c003 => 0, --Number placeholder
        p_c004 => NULL, --text placeholder
        p_c005 => to_char(SYSDATE,'MMDDYYYY') --Date placeholder
end loop;
END;Now I have a collection populated with rows I can use. In this example I have 2 NUMBERS, a TEXT value, and a DATE value stored as text. Collections can't store DATE datatypes, so you have to cast it to text and play with it that way. The reason is because the user is going to see and manipulate text - not a DATE datatype. If you are using this as part of a master/detail form, make sure that your SQL to grab the detail is limited to just the related data.
Now build the form/report region so your users can see/manipulate the data. Here is a sample query:
SELECT rownum, apex_item.hidden(1, c001), --Key ID
     apex_item.text(2, c002, 8, 8) VALUE1,
     apex_item.text(3, c003, 3, 3) VALUE2,
     apex_item.text(4, c004, 8, 8) VALUE3,
     apex_item.date_popup(5, null,c005,'MMDDYYYY',10,10) MY_DATE
FROM APEX_COLLECTIONS
WHERE COLLECTION_NAME = 'MY_COLLECTION'This will be a report just like an SQL report - you're just pulling the data from the collection. You can still apply the nice formatting, naming, sorting, etc. of a standard report. In the report the user will have 3 "text" values and one Date with Date Picker. You can change the format, just make sure to change it in all four procedures.
What is critical to note here are the numbers that come right before the column names. These numbers become identifiers in the array used to capture the data. What APEX does is creates an array of up to 50 items it designates as F01-F50. The F is static, but the number following it corresponds to the number in your report declaration above, ie, F01 will contain the primary key value, F02 will contain the first numeric value, etc. While not strictly necessary, it is good practice to assign these values so you don't have to guess.
One more note: I try to align the c00x values from the columns in the collection with the F0X values in the array to keep myself straight, but they are separate values that do NOT have to match. If you have an application you think might get expanded on, you can leave gaps wherever you want. Keep in mind, however, that you only have 50 array columns to use for data input. That's the limit of the F0X array even though a collection may have up to 1000 values.
Now you need a way to capture user input. I like to create this as a BEFORE COMPUTATIONS/VALIDATIONS procedure that way the user can see what they changed (even if it is wrong). Use the Validations to catch mistakes.
declare
j pls_integer := 0;
begin
for j1 in (
select seq_id from apex_collections
where collection_name = 'MY_COLLECTION'
order by seq_id) loop
j := j+1;
--VAL1 (number)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>2,p_attr_value=>wwv_flow.g_f02(j));
--VAL2 (number)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>3,p_attr_value=>wwv_flow.g_f03(j));
--VAL3 (text)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>4,p_attr_value=>wwv_flow.g_f04(j));
--VAL4 (Date)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>5,p_attr_value=>wwv_flow.g_f05(j));
end loop;
end;Clear as mud? Walk through it slowly. The syntax tells APEX which Collection (p_collection_name), then which row (p_seq), then which column/attribute (p_attr_number) to update with which value (wwv_flow.g_f0X(j)). The attribute number is the column number from the collection without the "c" in front (ie c004 in the collection = attribute 4).
The last one is your procedure to write the changes to the Database. This one should be a procedure that fires AFTER COMPUTATIONS AND VALIDATIONS. It uses that hidden KEY value to determine whether the row exists and needs to be updated, or new and needs to be inserted.
declare
begin
--Get records from Collection
for y in (select TO_NUMBER(c001) x_key, TO_NUMBER(c002) x_1,
             TO_NUMBER(c003) x_2,
             c004 x_3,
             TO_DATE(c005,'MMDDYYYY') x_dt
           FROM APEX_COLLECTIONS
           WHERE COLLECTION_NAME = 'MY_COLLECTION') loop
    if y.x_key = 0 then --New record
        insert into MY_TABLE (KEY_ID, COL1,
            COL2, COL3, COL4, COL5)
          values (SEQ_MY_TABLE.nextval, y.x_1,
              y.x_2, y.x_3, y.x_4, y.x_dt);
    elsif y.x_key > 0 then --Existing record
        update MY_TABLE set COL1=y.x_1, COL2=y.x_2,
             COL3=y.x_3, COL4=y.x_4, COL5=y.x_dt
         where KEY_ID = y.x_key;
    else
      --THROW ERROR CONDITION
    end if;
end loop;
end;Now I usually include something to distinguish the empty new rows from the full new rows, but for simplicity I'm not including it here.
Anyway, this works very well and allows me complete control over what I display on the screen and where all the data goes. I suggest using the APEX forms where you can, but for complex situations, this works nicely. Let me know if you need further clarifications.

For "select-form" in the same page, add a cancel button in editing status

Dear JHeadstart team
For "select-form" in the same page, I still have a trouble.
How can I customize the Tempalte File to make the editing page have cancel button to abandon the edit.
If I want to learn the the JHS's Template costomizing (.vm file) and where can I find more reference documents about JHS's Template costomizing (excepting "Oracle JHeadstart 10g for ADF Developer's Guide").
thanks!

Can you be more precise on what you want:
- should the cancel button be displayed when creating new row AND editing existing row?
- when pressing the Cancel button, where do you want to go, to the select page?

JSP Multi Row Edits and Struts Validator

Hello,
I followed this howto: http://www.oracle.com/technology/products/jdev/tips/mills/JSP_Multi_Row_Edits.html and implemented multi row editing. Now I'd like to use Struts Validator for validating data in multiple rows. Is there any howto document on this subject?
Thanks,

I think I will have to look inside the JHeadStart source code that extends DataAction, understand how that code works, and finally get the pieces I'm interested in...
