Master-detail code
With this code i am expecting to see a list of stores
associated with each category but instead I am only seeing the
first store in each category and that does not change when the user
selects from the drop down list.
<?xml version="1.0" encoding="UTF-8"?>
<stores>
<category title="Apparel, Accessories & Shoes">
<store storeName="American Way Thrift Store"

Hi Marlene,
You have the right idea, but your data is deceptively
complex and needs another solution.
Due to the XML structure, you have a nested data scenario:
Your <store> nodes repeat and this is an example of data that
can't be flattened correctly, as you have seen. You are just
getting the last store from each category.
If you use NestedXMLDatasets, you can achieve what you are
looking for.
The Js file to achieve this can be found in the 'includes'
folder in the Spry zip, or here:
http://labs.adobe.com/technologies/spry/includes/SpryNestedXMLDataSet.js
Include that on your page and then this code should work:
var ds1 = new Spry.Data.XMLDataSet("teams.xml",
"stores/category");
var ds2 = new Spry.Data.NestedXMLDataSet(ds1, "store");
<div spry:region="ds1">
<select id="test"
onchange="ds1.setCurrentRow(this.selectedIndex);">
<option spry:repeat="ds1"
id="{ds1::ds_RowID}">{ds1::@title}</option>
</select>
</div>
<div spry:detailregion="ds2">
<ul spry:repeat="ds2">
<li>{@storeName}</li>
</ul>
</div>

WF_SURVEYDEMO Code (wfsrvb.sql) for Master/Detail?
Hi,
I'm investigating the master/detail approach to a workflow issue I'm having.
I've become somewhat familiar with the Oracle Workflow Guide, and now I'm looking for the code behind the package WF_SURVEYDEMO, but I can't find a /demo or /demo/US directory anywhere.
Does anyone know where I might be able to find the code behind the WF_SURVEYDEMO package (filename wfsrvb.sql)?
Thanks.Hi,
Are you using standalone or embedded Workflow?
Emebedded should be in $FND_TOP/admin/sql. Standalone should be in $ORACLE_HOME/wf/admin/sql I think.
Alternatively, just pull the code out of the database by selecting from user_source or all_source.

Sample code to edit master detail records
Hi,
Could anybody please sned me the sample code to edit master and detail records.
Thanks,
KavithaArjuna,
Thanks for your reply. Unfortunately the 'switcher' code which makes an attribute editable, works on a 'Read-Only table' page but not on 'Master-Detail table' page. The switcher code is:
<switcher childName="${uix.current.RowID.inputValue == bindings.RowID.inputValue ? 'selected' : 'notselected'}">
<case name="selected">
<textInput model="${bindings.RequestedBudget}" columns="14" readOnly="false"/>
</case>
<case name="notselected">
<textInput model="${uix.current.RequestedBudget}" columns="10" readOnly="true"/>
</case>
</switcher>
We do have individual bindings for all table attributes. Any suggestions will be much appreciated.
Thanks, Ali. -
Questions on Master-Detail HTMLDB HOW-TO
Hi all
I have created a 3 page application based on the master detail how-to given at http://www.oracle.com/technology/products/database/htmldb/howtos/index.html
Instead of DEPT and EMP tables I have PERSON and PERSON_ADDR tables. The PK of PERSON is the person_id and the PK of PERSON_ADDR is the person_id and addr_start_dt. Person_id column in PERSON_ADDR is obviously the FK to the master table PERSON(person_id).
At first I had problems trying to create the pages themselves because the wizard always hides the person_id column on all the forms(and I don't want that,even though it is a sequence number I still want people to see it) , it being the PK, then somehow I managed it to display the person_id by replacing the EDIT link with the person_id itself. Now if a person already has an address and I click on EDIT then it copies the person_id values and others to the next page and all looks good but when I try to create a new address it does it ?? (It should take across the person_id as well)
My PERSON report is on page 1, when I click edit against a person it takes me to page 2 where I can see+change all the person details plus I can see the person_addr details. When I click edit against a person address it takes me to page 3 and I can edit all the address details nicely copied to the new page but when I click CREATE on the page 2, then all the fields appear as NULL on page 3( all the fields but the person_id should be null here). How can I fix this ?
Also, for my person address I would like to validate the address dates , there should be no overlapping start and end dates for a person's address. How to do this ? I think I will need to create a function to which I pass the person id and the new start and end dates and this function returns error message,if any, or null. I had a play around with validation and I think I need to use "function returning error text", what should I put in the "validate expression 1" box then...just something like
begin
my_function(param_1,param_2)
end;
If yes, then what variables would store the new start date and new end date of an address.
Lastly, for every table do I have to user a sequence number or a trigger to define a primary key, what if the primary key is just a character code and I want the users to add it ?
Thanks a lot in advance !!thanks Marc.
Yes you are right, I used the 1.5 viewlet. I will try the master-detail wizard now.
With the primary key problems, for things to work nicely in HTMLDB, do you suggest each and every tables should have a sequence number generated primary key ? We have some tables for various statuses like ACTIVE,CLOSED where these codes themselves are the primary keys, so you suggest making these codes unique keys but still have a sequence number PK ? Also when I want the users to enter the primary key themselves I will let them enter new ones but not update existing ones, so data entegrity is maintained.
I was able to work out how to create validations using "functions returning error text" but my problem is I need to be able to compare what the user has just updated/entered with the data that already exists in the table. I have a table called person_Address having columns like person_id, start_dt,end_dt and various other fields. The primary key is person_id and start_dt and I need to put a validation which avoids any overlapping addresses. Overlap as in there can be only 1 active address for a given start and end date range. Does HTMLDB has something like :new.start_dt the way we can write database triggers ? Please suggest a way to do this.
Lastly, how does HTMLDB handles error messages raised by table triggers. Can they be shown along with the item on the page as we can with the other HTMLDB validations ? I have many tables with all sorts of triggers and if any validation fails I generally do...raise_application_error(-20001,get_my_message(234));
get_my_message function returns the message text for message number 234 . Will this message be displayed somewhere or not ? Do I have to duplicate my validations , once in the triggers and then in HTMLDB as well ? -
Unable to View records in a master-detail form
In a master-detail form, I am not able to view records of the master/detail table
by accepting the values of the PK of the header table items.
Please tell me the exact steps, so that I can view the detail table records based on the header table PK items.
Thanks.Yes I wrote the LOV code in a different procedure. Now, the view is showing correctly. But I am now trying to update the viewed records.
The steps I am following in View Option is as below:
go_block('header');
clear_block(no_validate);
execute_query;
proc_lov;
go_block('item');
execute_query;
I am unable to commit the changes made in the blocks
The reason it is showing is : UNABLE TO update.....I saw the display_error.
The system is trying to update the PK part also..Why....Though PK party is clearly defined in the table as well as property palette. Pl. explain how to go about it. Uregent help is required once again. -
Adding button to report to link to master detail form
I want to add a button to a report to direct me to a blank master detail form to insert a new record. I have used the following code in the additional PL/SQL code section:
htp.formopen('PORTAL30.wwa_app_module.new_instance?p_moduleid=1271601405');
htp.formsubmit('p_request','Create New');
htp.formClose;
When I click this I get 'Page Not Found'.
But if I hit refresh I am directed to the correct form with the same url.
Any ideas on what the issue is?
Thanks.Hi,
Check this sample code.

Can I link from Interactive report Page 1 to Master Detail page 2?
Hi folks-
I know how to create a Page as an Interactive Report; it creates 2 pages automatically (primary page with the great interactive bar) and a 2nd page that's a single record.
I know how to create a Page as Master Detail, whereby I get a tabular list without the super interactive bar, and I can select a record, and get transported to a nice page with 2 regions (master on top, detail on bottom).
I want to have the First page from the Interactive Report, select the record, and go to the 2nd page of a MasterDetail.
Do I create the Interactive Report, and customize the 2nd page, to add a region?
Or, do I create both page types, and redirect from the 1st page of the Interactive Report to the DML Form from the MD report? I tried that, re-assigning the link from the Interactive Report to be a Link to Custom Target, and specify the page # of the Master-Detail page. And it is taking me to the right page, but the data from the selected row is not coming with me, and the detail in the bottom region is not appearing at all.
Can someone please give me a nudge as to the sequence I should be doing?
(As you can tell, I'm new to Apex.... I'm trying to use it to create a prototype or proof-of-concept for a database driven web application)
Thank you
MarionYes, I tried that after I wrote to you - and it's fine, but not what I'm after; it's only based on 1 table and I'm working with 2 tables.
Perhaps I can explain in better.
I want one page as an interactive tabular report (of the master records)
I want to select a row, and transfer to a page that has the corresponding row on top (as a form), and a tabular region below of records from a related detail table.
ie, I want page 1 from the Interactive Report, and page 2 of the Master Detail report.
OK - I just took the form page, and added a region below in a tabular report. And I'm getting the data, but I'm getting all the records (not just the ones associated with the single record on top. I figure I need to edit the Region Definition->Source (to specify that the id numbers need to match), but the code is not editable.....
So I am in Structured Query Attributes, and I've Modified the Join Conditions - but I still get all the detail records in the bottom region. I''m trying to add in the ( + ) qualifier, but it doesn't affect anything...
I'm soo close to what i'm trying to do!
Thank you for your continued patience and assistance
Marion
here's the Source I have for the region..... (I'm including the excess ID columns just for learning purposes)
SELECT
"PHONENUMBERS"."PHONE_ENTITY_ID" "PHONE_ENTITY_ID",
"ENTITIES"."ENTITY_ID" "ENTITY_ID",

Refresh of Master/Detail does not work after validation failure
After page validation stops further page processing of a Master Detail page, I get the following Oracle Error on display of the Detail portion :
<code>
ORA:01445: Cannot select ROWID from, or sample, a join view without a key preserved table.
ORA-06510 - PL/SQL unhandled user-defined exception.
</code>
Any clues as to why this might occur? The Master portion of the page displays fine along with the appropriate custom validation error message. It is just the detail portion (from a SQL based report) that is causing the problem. I do not use a ROWID either!
Thanks!Just an FYI for everybody who may have this very same problem in the future. I fixed the error and it had nothing to do with ROWID or views or anything like that. Under the Page Rendering section where you define the region definition under the source section, I had included the 'order by' clause in my SQL statement. This was the cause of my ORA-01445 error! When I removed the clause from the source definition and instead included it within the Report Attributes by checking the Sort box for the appropriate column (thus allowing APEX to generate the sort for me), the error disappeared! The Oracle error message would NEVER have given me a clue into what caused the error. I just happened to think 'what if I take the order by clause out'! How's that for a flukey fix!

Requerying on Master Detail form
Hi,
Does anyone know how to set up PL/SQL code to automatically requery on a master detail form after insert/update? For example, if I insert a record on the master part of the form, I would like that record to automatically show up after the insert/update. Also, if I insert a record on the detail part of the form, I would like that record to automatically show up after an insert/update.
Thanks,
MartinHi Krishnamurthy,
Thank you very much for the code. The code for the most part acts like I want it to except when I initally insert a master record. In my case, I have the form set up so you have to insert a master record before you can insert any detail records. Therefore, after the user clicks save, that master record needs to come up. The code you gave me only brings up the current master record if you are inserting detail records (which is great, that is what I want it to do). I have modified the code you gave me so when a user is just inserting the master record, the master record automaticaly comes up rather than the first record in the table. However my code makes the form run slow (about 13 seconds to save). Do you know of another way that I can make the form act like I want it to. Below is my code.
Thanks again,
Martin

Master-details problem: How to access the parent EO/VO in child side?
Hello
Refer to the reply of posting
Re: How to insert new records in Master and detail Forms.
I have got the following questions
The approach for setting the master-details relationship works well, however, in this example,
I have overriden the create(AttributeList attributeList) method of VO2, so after calling
DCBindingContainer dcb = ADFUtils.getDCBindingContainer();
OperationBinding oper = dcb.getOperationBinding("CreateInsertVO2");
oper.execute();
, it will enter the create() method of VO2, at this point, i can only access the argument attributeList
which stored the key value that link up parent and child, however, how can i get the entire VO1
for accessing the value of all VO1's attribute?

I have mapped a createInsert action in the blinding layerThis is OK.
Neon wrote:
Do you mean that i have to create createRow and insertRow action in blinding layer?No. The createInsert operation does just that

Or call these function in the VO overridden create() method?No. You can't do that.
In conclusion, I don't understand why the accessor returns null. Maybe someone else can shed some light... ?:|
One last suggestion from me is to try getting the VO1 directly from the AM instead.
This should work - it is not a recommended practice through.
Use the following code:
VO1RowImpl vo1 = (VO1RowImpl)this.getVO1();
// ensure that the VO1 VL accessor is properly initialized
if (vo1 == null) {
vo1 = (VO1RowImpl)((YourApplicationModuleImpl)this.getApplicationModule()).getVO1().getCurrentRow();

Master Detail Form - How 2 update a field in the Detail form using a query?
Hello,
I have a master detail form with, each master record having a fixed(6) number of detail records. One of the fields in the detail record is the PART_DESCRIPTION field. I am trying to update this field by querying Table_X. TABLE_X is in the format of (desciption id, description). Description id runs from 1 to 6.
When the form displays, the PART_DESCRIPTION field for the 6 detail records needs to be automatically populated with the six values of description stored in Table_X. How can this be done?
Tried using session storage objects, but made no headway.
Would greatly appreciate pointers on how to go about doing this.
Thanks.
DevIf you are on a Portal Version lesser than 3.0.9.8.3, then please try the following to populate
the PART_DESCRIPTION field.
Steps:-
1> Edit the form and go to the Additional PL/SQl section and put the following code in the
"...after displaying the page area" :-
declare
type t_vc_arr is table of varchar2(4000) index by binary_integer;
l_arr_desc t_vc_arr;
l_form_name varchar2(200);
l_form_state varchar2(500);

Master-detail list - how to spread over multiple columns
I am using the master-detail functionality to create a image viewer.
I have a long list of master thumbnails, and rather than having them go down the page in one column, I would like to make them spread over 2 or 3 columns before the detail column.
(example of format I am trying to achieve - http://www.franbainbridgephotography.com.au/gallery.html (I dont mind whether master thumbnails are on right or left of detail photo))
You can see my problem on http://www.wcwra.com/webpages/images.php
Is this possible with the master-detail functionality?
Thank you!The brilliant David Powers has fixed this for me on the main forum (vw2ureg was v close). David's answer is :
There is no way of making a single dataset repeat in multiple columns, because it's simply one element being repeated over and over.
However, with a little out of the box thinking, you can do it quite easily with thumbnails. Instead of putting the master column repeat region in a block level element, use an inline element, <span>. Images are treated by browsers as inline elements, so this should work just fine. Change the following code from this:
<div spry:region="dsPhotos" class="MasterContainer">
<div class="MasterColumn" spry:repeat="dsPhotos" spry:setrow="dsPhotos"
spry:hover="MasterColumnHover" spry:select="MasterColumnSelected">{Caption}</div>
</div>
to this:
<div spry:region="dsPhotos" class="MasterContainer">
<span class="MasterColumn" spry:repeat="dsPhotos" spry:setrow="dsPhotos"
spry:hover="MasterColumnHover" spry:select="MasterColumnSelected">{Caption}</span>
</div>
In your CSS, set the width of the MasterColumn class to the width of your thumbnails, and the width of MasterContainer so that it's wide enough to accommodate two or more thumbnails. The thumbnails will flow into the column two or three abreast. -
Master/detail layout - how to have 'detail' hidden by default.
The 'master/detail layout' option for spry datasets are great but how can I get the page to load with all the 'details' hidden until the user selects from the 'Master' column to reveal the details?
Hiya,
Don't know whether you are still looking for a solution, but if you are, please take a look at:
"Using URL Parameters to Control Data Regions"
I used the info there to create a Master/Detail page at
http://www.myosanthe-bernhard-huber.com/html/fotobergtraining.php
(which calls its data from an HTML DataSet)
The detail region is empty when the page first loads because I've used SpryURLUtils to 'listen' for a url parameter so that I can load a specific row's content from an external link (eg http://www.myosanthe-bernhard-huber.com/html/fotoalbum.php which is also made from the the same dataset).
A side result is that If the parameter isn't included in the url when the page loads, the detail region remains empty.
The relevant code from the <head> of the page is:
<script src="/SpryAssets/SpryData.js" type="text/javascript"></script>
<script src="/SpryAssets/SpryHTMLDataSet.js" type="text/javascript"></script>
<script src="/SpryAssets/SpryURLUtils.js" type="text/javascript"></script>
<link href="/SpryAssets/SpryMasterDetail_foto.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
<!--
var dsTrain = new Spry.Data.HTMLDataSet("/html/fotos/fotodata.htm", "TrainData", {sortOnLoad: "Nr", sortOrderOnLoad: "descending"});
//Get the URL parameter for the row number
var params = Spry.Utils.getLocationParamsAsObject();
//Set an observer so that when the data is loaded, we update the current row to the url param value
dsTrain.addObserver({ onPostLoad: function(ds, type) {
dsTrain.setCurrentRow(params.row); }
//-->
</script>
This may not be the best or easiest way (I'm a beginner myself), and I haven't yet worked out how to move back to the top of the page when a master-link is clicked, but this may be useful for you.
Best regards,
Len
