Won't display or edit in master/detail

I suspect that this is a reserved word thing. We are controlling access to the application through a users table. One of the columns is oracle_id. I'm writing a master detail to add data to the users table (it's the detail). The wizard creates the oracle_id column, but at first it wouldn't display it. I've tinkered some, but it now will display the column as null (in italics), and won't allow it to be edited.
Is there a workaround of somekind ? The table is already in production for another application, so I can't change it.

Figured it out after some digging in the documentation. This was a case where we allowed users to manually enter the primary key. HTMLDB doesn't like this at all. Our workaround was to create a sequence number and change it to the primary key, then create a unique key for what was the manually entered primary key.

How to display more rows in Master-detail form

I am working on APEX3.2.
I have a master-detail form. The detail form always display 15 rows. However, my customer wants the detail display all the rows. I tries to configure the Number of Rows in the report. It doesn't work. How do I do it?
Thanks a lot!

Hi:
To increase number of rows displayed you have to set Number of Rows and pay attention to both Number of Rows (Item) and Maximum Row Count.
After that if didn't work, sign out or close the browser then open it again. Sometimes it keeps the value in current session.
Saad,

Binds in Master/Detail Reports: Problems and Solutions

I've been trying to use bind variables in the master report of master/detail reports with multiple detail reports; but, I've been getting a problem with the detail reports not displaying data.
Here's a sample sequence of events:
1) Select the master/detail report under User Defined Reports.
2) Connect to a DB (if necessary).
3) Enter any value(s) for the bind(s) for the master report.
4) Select a row in the master report.
5) The currently selected detail report displays column names and data.
6) Select a different detail report.
7) Nothing displays except column names.
8) Select a different detail report.
9) Nothing displays except column names.
10) Click the currently selected row in the master report.
11) Now the current selected detail report displays (column names and) data.
I have found that if, I am more selective with my bind variable names, I can get things to work as expected.
First, let me show an example of some SQL that was giving me problems.
Master Report:
select distinct OWNER
from SYS.ALL_OBJECTS
where (OWNER like :OWNER or :OWNER is NULL)
Detail Reports:select *
from SYS.ALL_OBJECTS
where OWNER = :OWNER
and OBJECT_TYPE = 'INDEX'replacing 'INDEX' with other values for the other detail reports.
(I did have this problem with other SQL too but hopefully this SQL will run on everyone's DB.)
The first solution I found was to change the name of the bind in the master to something like OWNER_BIND.
The second solution I found was to change the master to
select distinct OWNER as POWNERand change the detail reports to
where OWNER = :POWNERAnother solution might be to adjust the bind variable names' case, but I didn't look at that.
While I was trying different things to get this to work, one of the goofy things that SQL Developer did was add <binds>s to the <query>s of the detail reports in my UserReports.xml. IIRC, it even did this to a master/detail report that I was not editing. So, if you run into this problem, you might want to open your UserReports.xml and clean it up by hand. (Actually, that might be good advice for other problems too.)
Tip: I've had other problems with my User Reports such as disappearing reports; so, not only do I regularly make copies my UserReports.xml, I also save report(s) into separate XML files and use Tools > Preferences... > Database > User Defined Extensions to add REPORT-type extensions to SQL Developer. (Kris Rice talked a bit about REPORT-type extensions in this blog entry: http://krisrice.blogspot.com/2006/11/xml-extension-points-reports.html)
FYI: I'm using sqldeveloper-1.1.2.2579 on Windows XP w/ SP2. The DB is Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production.

Here is the complete XML exported from a problem report. If you want to use this, save it as an XML file then import that file from within SQL Developer (ie, right-click on User Defined Reports and choose Import).
Notice that there are <binds>s on the detail reports. They don't belong there; only the one on the master report belongs. (The <binds> is specified by the Binds tab when creating a report. They are for prompting the user for value(s) and you cannot do that in child reports.) Even if I removed the <binds>s from the detail reports before importing the XML file, I still see the problem. SQL Developer also ends up putting them back. I think that it might happen to each detail report individually as it is visited when using (ie, not editing) the master/detail report.

Visualize master-detail relationships using SQL Edge 1.2

SQL Edge 1.2 released by Bay Breeze Software (http://www.baybreezesoft.com) is an Eclipse Rich Client application that allows users to execute SQL queries, browse schema information, and visualize master-detail relationships.
With SQL Edge, users can use only one query to retrieve data in a master table, and then browse data in all related detail tables. Users can also insert, edit, and delete table records in the data grids.
SQL Edge has four perspectives. The Query Perspective allows users run any SQL queries, while the Schema Perspective displays table schema information. There are two relationship perspectives. The Relationship Table View displays data in the master-detail style. The Relationship Tree View displays master table records as top-level tree nodes. The nodes can be expanded to reveal any level of related detail records. In addition, clicking any node will display the corresponding data in a detail grid.
The following summarizes SQL Edge's major features:
(1) Support any JDBC compatible databases.
(2) Allow users to specify JDBC drivers at run-time, and provide wizards to help setup JDBC connections. Easy to install, and easy to setup.
(3) SQL editor with syntax highlighting based on currently connected databases.
(4) SQL edtior allows users to execute SQL queries asynchronously. Users can cancel the execution by click the "Cancel" button or just close the SQL Editor.
(5) Schema perspective displays the table schema information, including column definitions, primary key, indexes, and foreign keys.
(6) Relationship table view displays the related data in master-detail style, with master table data shown in the top grid, and all related detail table data in a list of bottom grids.
(7) Relationship tree view displays the master table records as top-level tree nodes, and the related detail records as child nodes. Click any of these tree nodes will display the corresponding record data in a detail grid.
(8) Allow users to insert, edit, and delete records in the master and detail grids of the relationship table view and relationship tree view.
(9) Allow users to define master-detail relationships even between tables in different databases. This enables the relationship table view and relationship tree view to display data relationships between tables in different databases or without pre-defined foreign keys.

Hi, Martin.
Maybe you don't need a master detail relationship. Do you need to do changes in your detail block, or just queries?
If just queries, you can create your second block based on a From-Clause Query, and change the QueryDataSourceName property with a When-List-Changed trigger in your T-List.
I know this is a little vague but, without knowing what you need to do in the second block, I'm afraid to tell you more.
Feel free to mail me directly, if you need some pointers about Forms.

Problem with apply changes on master-detail with respect to date handling

dear sir,
i have one tabler where in i have created from_Date and to_date as varchar2(30) each. I stored the from date as 'dd-mon-yyyy hh24:mi' I had written before header process for calculating no of days between from_Date and to_Date using the said format. If to_Date is null then first i store the value as
to_char(sysdate,'dd-mon-yyyy hh24:mi') and then convert it as to_Date(substr(to_Date,1,17),'dd-mon-yyyy hh24:mi'). this calculation of days procedures works fine in sql command mode.
when i am handling through master-detail page i works fine when there is null value inf to_Date vc2 column. if i store using date picker dd-mon-yyyy hh24:mi, the data is getting stored but subsequent edit through master detail give error as ora-01722 unable to fetch row. Manually if i set the to_Date as null pages works fine. I spent lots of time and unable to understand the mistake i do.
if anybody could help me, i will be much obliged.
thanking you,
yours

I think the best would be if you create an example on apex.oracle.com and I will debug it.

Creating a new row in a master detail VO relation and its consequences.

Hi,
I'm currently facing a lot of problems which make me doubt if my perception about the whole ADF entity-view object mechanism is right.
I have a page which displays data from a master detail VO relation (master offer - detail officeinfo). I also have a small dialog LOV window which makes it possible for me to select an office to match up with the current offer... Both the office LOV and the officeInfo detail use the same Office entity object.
This worked perfectly fine until I wanted to add create NEW offers. I created my own insert method which basically performs a createRow on the master VO and inserts the newly created row in this VO. On a sidenote, I also fill out some default data read from a property file, which is why I decided to implement my own insert method in the first place.
Initially, the problem was that the inputText fields of the detail VO (OfficeInfo) were not displayed at all. I imagined that I also had to perform the create and insert methods on the detail VO and indeed, from that point on all inputText fields were displayed and my page was ready for input.
Yet today, I notice that in my Office LOV which is based on the same entity as the one my detail OfficeInfo VO uses, this newly created row is ALSO visible. To me this is quite unwanted and surprising behavior. I did not expect the row already to be visible in the LOV, since basically it's just an empty row ready for input...
Am I perceiving things wrong? Or anyone has a nice solution to fix this?
Thanks,
Douglas

Hi Douglas,
It is happening because you have created an updateable office LOV which is based on same entity object used to save your newly created records.
Use readonly LOV based on plsql query in your page and you can keep rest of the thing as it is.
I think it will solve your problem.
Cheers,
Suyog

Master/detail/detail

using jsf/adf bc. I've got a jspx which needs to display data from a master/detail/detail setup. In a 'create' mode, i'm programmatically handling the create/insert stuff for the new master and detail rows. I'll try to explain my problem using a Departments/Employees/EmployeeAddresses example.
I've created a view link between Departments and Employees. I've created a view link between Employees and EmployeeAddresses. These have all been added to the active data model so that it looks like this:
DepartmentView
-Employees via Employees1
-EmployeeAddresses via EmployeeAddresses1
The code i use to create/insert the master and subsequent detail rows is as follows:
//create master (department) row
ViewObjectImpl vo = getDepartmentView();
Row departmentRow = vo.createRow();
vo.insertRow(departmentRow);
//create the detail (Employees) row to be associated with its master (Department)
ViewObjectImpl employeesVO = getEmployees();
Row newEmployeeRow = employeesVO.createRow();
employeesVO.insertRow(newEmployeeRow);
//create the detail/detail (EmployeeAddresses) row to be associated with its master (Employees)
ViewObjectImpl employeeAddressVO = getEmployeeAddresses();
Row newEmployeeAddressRow = employeeAddressVO.createRow();
employeeAddressVO.insertRow(newEmployeeAddressRow);
The problem seems to be with the last level detail row, the one for EmployeeAddresses. creating in this fashion doesn't seem to associate the new EmployeeAddress row to it's master, Employees. Although when the page is rendered, i can see that new rows have indeed been created/inserted for each of these view objects. After filling in valid values and committing, i get the JBO-27014 (Attribute is required) error for each attribute in the EmployeeAddresses table. So, it's as if this EmployeeAddress row that was created is not tied in with the Employees row, which is in turn tied in to the Department row.
Note: if i remove the create/insert code for this last detail row (EmployeeAddress) and simply have a basic master/detail setup between Department and Employee, everything works great when i create new rows this way and save. It seems that my problem stems from the fact that i'm adding another detail level onto my master/detail setup. Is there something different i should be doing?

Hi,
Thanks guys for your response.. i did it myself following way..
created 2 view links. having same source.
added both vos to same source in application module it self.
Regards,
Santosh.

JDev 11g unable to refresh master-detail-detail using WebService proxy

Hello,
I need to access multiple webservice operations and display them in a master -> detail -> detail2 tables. I've created web service proxy and javabean data control on top of the operations. All three tables are loaded fine on the initial call. When I select a new row in the master table, the detail gets refreshed but when I click the a new row in the detail, detail2 does not get refreshed based on the row selected in detail. It always shows the records for the first row in the detail table.
master table is for projects
|
|_ detail table is for tasks
|
|_ detail2 table is for employees
Since this logic is built on top of web service proxy that requires complex type as parameter, I've add getProject, getTask method as shown in http://susanduncan.blogspot.com/2006/09/dealing-with-complex-input-params-in.html. What I have noticed that getTask always returns first row values.
Any pointers?

One more thing I have noticed is that even if I click on the row in detail table, the web service that connects master table with detail table gets called. The response back from webservice is what goes into the detail table.

Question of displaying Task Flow Region in Master-Details pattern

We have a master-details page. There is a region on the details pane along with other widgets and the content of that details pane including the region depends on the row selection on the master table list.
The first time page loads with no row selection on master table so this details pane displays nothing. When I select one row on the master table and the details pane and its region can display data of the row in master table properly.
After several selection, I navigate to another page and then go back to this master-details page again, it automatically selects the row which was selected last time. And in the details pane, the region whose content was created basing a task flow call cannot display corresponding data of the default selected row while other widgets in the details pane can display corresponding data properly.
The reason of having this problem is the region's parameter is generated before the selected row is determined. When the task flow call in page definition is parsed, the parameter of this task flow call is created before component binding of the master table. It means when the task flow call is parsed and generating the parameter, the ADF page believes there is no row selection of the master table because the component binding is null at that time.
So my question is how to make the this task flow call for that region create the task flow call parameter after the component binding of the master table? Or is there any way to force a refresh of the region/task-flow-call after the render of response? Or is there anyway to disable this "auto-select" on the master table after navigating to other page?
(My jdev version is JDEVADF_11.1.1.6.0_GENERIC_111205.1733.6192.1 )
Edited by: user790224 on Sep 6, 2012 4:16 PM

The reason we are using master-details patter here is it is designed in that way and the region is displaying the data of a selected row there.
There is no master-details relationship on model layer. But the content of the region is from the result of several other Java API calls which call the task-flow from an external component.

Master/Detail form with modal edit

I have a master/detail form that I generated using the wizard that I want to change to have a modal Edit button; i.e. the behavior I want is that the form view is initially read-only and you then have to click an Edit button to make the form editable.
I figured out how to do this for the master row by making the edit button redirect back to the same page with the request set to 'EDIT' and then making all the page items read-only with a condition REQUEST <> 'EDIT'.
I cannot find a good way to do this for the detail rows, which are actually a report with editable columns. The problem is that the 'Tabular Form Element' section of the 'Column Attributes' page does not have a read-only condition.
The only work around I can come up with so far is to have a second read-only report region with the same SQL query and then display either the editable or non-editable report region conditionally depending on whether the request is EDIT. But this obviously not ideal (having same SQL in two places, etc.).
If anyone can think of a better way to do this, I'd be grateful.
HTML DB Team: Can you log the addition of a read-only condition attribute on editable report columns as an enhancement request?

Simply add the lookup table to the FROM clause and join its PK with the FK in the master table in your query. That's basic SQL, and you definitely must get a good grasp of SQL to do more than very basic work in APEX.
For a good example, please see http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10498/build_app.htm#BCEBJJGB

Controlling display of details in Master Detail form

Hi
I have a Master Detail form that opens up only in update mode. The master record is display only and only one of the detail fields, "Qty Fulfilled" is editable and the rest are display only. So, the form currently, has a text box only for the Qty fulfilled field.
I set the # of detail rows option to 5. So my form shows a column of 5 boxes, even if there are only 2 detail row.
How do I hide the remaining 3 boxes which have no data in them?
Please help , this is urgent.

Display only current row in master detail

Hi every body greetings. I am facing a problem in master detail. I create a record in master. After i click create button i want only that record to be displayed so that i can edit it to add detail records. Kindly help me? thanx in advance. The problem is i dont know where the record goes since all the other records are also displayed.

Hi Michelle,
Just wondering if you got an answer? I want to do the same exact thing - seems like a simple enough requirement and fairly intuitive flow: I am in my Master-Detail form performing a Create action and I want to add the Detail portion on the same screen rather than hit Create on the Master - then have to go back, Search for that Master record and update it in a separate action by adding the Detail.

Master-detail: detail field not displayed after changed by master field

I want to use the Depends on item with Clear/refresh value functionality in a master detail situation. Within the same group it is no problem to use the setter method of a field to change a second field and then displaying this new value. But in the detail group, I can not select items from the master group as a depends on item.
In the setter of the master field, the value in a field for each row in the detail (table layout) is updated. The only problem is that this updated value is not displayed, the old value doesn't change. When saving the changes, the displayed value is committed to the database. When de updated field is not displayed at all, the correct value is saved, so I know the detail field is updated.
How can I make sure the displayed value in the detail is displayed after changeing a master field? I already gave the detail field the correct partial trigger.

Wouter,
I guese you don;t see the changed value when you display the detail item because after the depends on item update changed the detail item, JSF procesing continues and the detail table changes are sent to the server which will override again the detail item attriibute, resetting it to the old, still displayed value.
So, the trick is to get PPR working. Make sure the partialTYriggers property of the detail item is set to the value of the id property of the master item. If it still doesn't work, try setting the partial triggers property on the table, instead of the individual item.

UIX Master-Detail - Find button does not display detail lines

Hello,
We have a master-detail UIX page. Master has one attribute only. When 'Next' or 'Previous' buttons are pressed, the next master-detail records are displayed.
However, when master attribute's value is changed by the user and the 'Find' button is pressed, the new detail lines are not displayed. Also we get following error:
JBO-26080: Error while selecting entity for <ViewObject>
Has anyone experienced this issue before?
Thanks, Ali.

Please dis-regard this post. The correct sequence is to click on Find button, enter new value then click on Execute button to query new values.
Thanks, Ali.

Won't display or edit in master/detail
