Cannot Forward - Master-Detail

Scenario:
In a master-detail situation where there are contacts and notes, I want to forward to the master level when the save button is pressed.
Using the Struts Page Flow Diagramer I create a Forward from notes - to > contacts. Then I edit the notes uix page and add an event-handler for the Commit event. (<submitButton event="Commit")
Specifically;
1. Insert inside handlers - event
2. Name the event - Commit
3. Insert inside event - Commit
4. UIX servlet - Go - FowardContact1
Rebuild and run the app. Proceed to the detail level, press save and it commits the transaction but it does not forward.
What am I doing wrong???
Thanks,
BG...

Bill,
You should not need to create a UIX event handler for this. The generated page, already includes a save button that commits, right?
All you need to do is create the forward and name it "Commit". By creating an event handler, the event-based forwarding meachinism no longer works.

Hi timo,
Thanks for ur reply...
we are using unbounded taskflow.
In Controller class(page def file), we refered the class that implements PagePhaseListener
The following override methods has created
public void afterPhase(PagePhaseEvent pagePhaseEvent) {
//In this area we used to read the session object file which is written and sent by another application(application to application navigate).
If session object file exists,will allow the user to navigate into the requested page else will navigate in to login(security aspect).
public void beforePhase(PagePhaseEvent pagePhaseEvent) {
Is we used Controller class wrongly ???
Is there any relationship with region controller???

Cannot delete record in master detail form in apex 4.0.1

Dear all,
I've created a master detail form in apex 4.0.1. Inserting and updating records is working. But when i want to delete a detail or master record, nothing is happening. The delete button is just not working.
Can someone please tell me if this is a bug, and if so, is there a work around to solve this problem?
Thanks,
Diana

Hi,
Am I the only one having this problem?

Master Detail Wizard: Cannot Redirect Detail Form to Detail Form 2

Dear all,
I created a Master Detail Report Forms using wizard where Master Report has a link to its Detail1 form, which has a link to its Detail2. However, the page redirection didn't work from Detail1 to Detail2 whereas Master to Detail1 worked.
I checked the region button in Detail 1 that did the redirection, I didn't find anything wrong (I think).
Suppose Detail1 is page 210 and Detail2 is page 220, The following is my configuration:
- Under "Action When Button Clicked" tab:
1. Action is set to "Redirect to Page in this Application"
2. Page is set to 220
3. Request is left blank
4. Clear Cache is set to 220
5. Set These Items is set to
P220_TICKET_ID6. With These Values is set to
&P210_TICKET_ID.7 Database action is set to
- No Database Action -Is there any other place that I should check that might effect the redirection? Please advice.
I'm using Apex 4.0.2
Best regards,
Val

The answer to this problem appears to be that there is a bug in HTMLDB 2.0 (at least thats what I'm thinking) in that it is not handling dates correctly when passing them to the detail form. Once I modified the date column in the detail form, and formatted it with TO_DATE, it all worked fine. I would think the wizzard would do this. Oh well...

Cannot install Sample Master Detail (Packaged Application)

When trying to install the Sample Master Detail packaged application
on the new APEX.Oracle.com (running Application Express 4.2.0.00.22),
I'm getting an error.
After selecting it from the Packaged Applications page, and clicking the "Install Application" button
on the Application Builder/Packaged Applications/Sample Master Detail/Install screen,
I get the following:
Execution of the statement was unsuccessful. ORA-00001: unique constraint (APEX_040200.WWV_FLOW_MESSAGES_IDX1) violated

p_message_language=>'en',
p_message_text=>h);
null;
end;
ORA-00001: unique constraint (APEX_040200.WWV_FLOW_MESSAGES_IDX1) violated
I tried in a workspace that had some existing applications, and a colleague tried
in a new workspace that had just been allocated by APEX.Oracle.com.
I was able to successfully install the Sample Data Loading application after trying to install
the Sample Master Detail packaged application.
Anyone else having this issue?
Thanks in advance!

I think the detailDisclosure state needs to be saved and retrieved from the session.
I'm not sure using a table with singleSelection inside a detail disclosure is supported. Are you doing master-detail inside of detail disclosure? Detail disclosure is not really meant for that. In jdev 10g preview we make hooking up a master-detail easy. Here's a link to some doc about it.

OBIEE 11g: Inconsistencies with Master-Detail events and Navigate to BI

Hi everyone,
I'm getting some pretty annoying inconsistencies with the Navigate to BI Content action as well as the Master-Detail events. Basically the main issue I get is that 90% of the time, the click does nothing.
It's a pretty simple setup, I am setting up bulb gauges to act like a fancy column selector. The bulb gauges are setup to pivot based on a Metric Type column. The goal is that if you click on "Metric 1" bulb a trend report should refresh to show Metric 1. If you click on the "Metric 2" bulb, the same trend report will show that metric.
Here's how I implemented it:
Dashboard Tab A -- Uses Navigate to BI Content
1) I have a prompt on Fiscal month in dashboard tab A.
2) I created the bulb gauge and put it in dashboard tab A
3) Setup the interaction on the bulb measure to navigate back to Dashboard Tab A.
3) Prompted the trend on Metric Type column and put it in dashboard tab A.
4) In theory, clicking on the bulb, should navigate back to the same tab and update the trend report appropriately
5) In reality, nothing happens.
6) The only way I can get the navigate to work is if I first change the value in the fiscal month prompt and click Go. Then I click on the bulb and the navigation will work ONCE. After that it's broken again.
Dashboard Tab B -- Use Master Detail -Events
1) Pretty much same situation as dashboard A, but instead of navigate to BI Content, I use the master-detail events.
2) Pretty much the same results. I cannot get it to consistently work, in fact the trick with the filter didn't do anything.
3) One thing I tried was cleared my browser history completely (Mozilla Firefox) and then launched the page. It work for about 5 clicks and then stopped.
Either way, neither of these are working properly for me.
Has anyone else had these issues?
-=Joe
Has anyone else had an issue with this?

So someone explained to me that master-detail events only occur within a single report. They cannot be used to communicate across two different reports.
That is significantly less useful than I originally thought. I honestly that it was a method of communication for one report to update other target reports that are all listening on the same channel. That would have been a powerful feature. A single report refreshing other views in the same report is still useful, but not as much.
That being said, I still don't understand what the heck is going on with the navigate to BI content feature. I've been testing it out. It works with pivot tables and regular tables. But the moment I add a graph, gauge or even a "Filter" view into the dashboard page, the click stops working. Really really strange stuff.

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!

Creating master detail rows

using adf/bc with jsf. I have defined a master detail relationship between two entities. This relationship is a composition relationship. The entities are related by a view link which link the master and detail view objects. i have a need to create/insert a master row and a detail row programmatically "on the fly" so that when the jsp renders, the user will see blank inputs for both the master and detail view objects. The problem is that the primary key of the master record is not known at creation time ( it will be entered by the user) and therefore the detail record cannot be created by the framework because of the unknown value of the parent's primary key. I was hoping the following section in the adf guide would eliminate my problem, but it doesn't appear to:
This is from section 26.7.3.2 of the adf developer's guide
Note: An alternative to the programmatic technique discussed
above, which solves the problem at the J2EE application layer, is the
use of deferrable constraints at the database layer. If you have control
over your database schema, consider defining (or altering) your
foreign key constraints to be DEFERRABLE INITIALLY DEFERRED.
This causes the database to defer checking the constraint until
transaction commit time. This allows the application to perform DML
operations in any order provided that by COMMIT time all appropriate
related rows have been saved and would alleviate the parent/child
ordering described above. However, you would still need to write the
code described in the following sections to cascade-update the foreign
key values if the parent’s primary key is assigned from a sequence.
This approach did not help in allowing me to create the detail record without first knowing the value of the parent's primary key record in a composition relationship. The only thing i've found to work is define the relationship as just an association, and not a composition. However, this is a true one to many (composition) relationship and i would like to take advantage of some of the features of the framework that are there when a relationship is defined as a composition relationship. Is there any way to do what i need to do with a composition relationship defined between these two entities? Thanks.

Hi,
I guess you need a "Cascading LOVs".
1) Create viewObject for country values list. Named VO1.
2) Create viewObject for state values list. Named VO2.
3) Create view criteria for (bind variable) VO2 which can restrict the result by country.
4) Create view accessor to get VO1.
5) Create view accessor to get VO2. Define the bind variable value which can provide country info dynamically. I guess it should be a Groovy expression.
6) Create country LOV on step 4) view accessor.
7) Create state LOV on step 5) view accessor.
Done
On the view layer, you may enable PPR between country and state attributes.

Many to many master detail form

Hi All,
APEX 3.1.2 on SuSE 10 Oracle 10.2.0.3 64 bit
I am new to APEX, but used OAS several years ago. Back then I hardcoded all htp.print commands. We are building an intra-team application to track system relationships. For example,
web interface 3 --> application server 2 --> database 6
Our tables are similar to the following
SYSTEMS
system_id (unique sequence)
system_type_id (database, app server, apache, etc.)
SYSTEM_TO_SYSTEM
publishing_system_id - number
consuming_system_id - number
We would like to have a master detail form where we would query database 6 for example, and then see all related systems one level below it (application server 2 in the example above). I have been able to query the related systems and show them in a drop down pick list on the detail form, but I cannot edit them.
The wizard asked for the primary key of the detail table, which in this case is not a sequence generated value, but a pick from a systems table lookup on system_id/system_name.
If the master form would automagically lass the system_id to the publishing_system_id on the detail form, and allow me to update that with a picked system_id tied to consuming_system_id, that would be perfect.
I can write the htp calls I mentioned earlier, but I am sure I am missing something.
Does anyone have any best practices for this?
Thanks!
Steve

Hi Steve,
Here is an example which might help you:
http://apex.oracle.com/pls/otn/f?p=43368:35
Here, I have used two tables e.g. test1 and test2. Test1 has an id column which is just a sequence column and the name column in this table has a unique key.
Table test2 has id column as primary key and name1 column is linked with Test1 table on the Form. Name2 column is not required to be linked with Test1 table.
If this is what you are after, then I can give your more detail for it.
Hope it helps.

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 Details Input Form

Hi,
I'm using JDeveloper 10.1.3.1, ADFBC JSPX, I've created two tables dept with deptid and deptnm primary key deptid, emp with empno, empnm and deptid foreign key deptid references dept table.
i've created business component Diagram, in that i dragged 2 tables. i've created views for that tables, and view link between these two. i've creaed Data Control as a Master Details. in Jspx, i dragged Dept View as a creation form, and down of that, Emp as a creation form, then from operations, i dragged commit and rollback buttons. When i'm testing in Application Module, it's running perfectly ok, while running jspx these errors are comming, how can i solve this.
1. JBO-27027: Missing mandatory attributes for a row with key null of type AM.EmpView1
2. Empno - JBO-27014: Attribute Empno in AM.EmpView1 is required
3. Deptid - JBO-27014: Attribute Deptid in AM.EmpView1 is required
Thanks and Regards,

Hi,
Whatever link u've send i've tried that with using Service Requests and Products Tables.
public Result newServiceRequestForNewProduct(String prodName,
String prodDesc,
String problemDesc,
Number customerId){
//1. Create a New Service Request
ServiceRequestsImpl newSR = createNewServiceRequest();
//2. Create a New Product
ProductsImpl newProd = createNewProduct();
newProd.setName(prodName);
newProd.setDescription(prodDesc);
//3. Set the product id to which service request pertains
newSR.setProdId(newProd.getProdId().getSequenceNumber());
newSR.setProblemDescription(problemDesc);
newSR.setCreatedBy(customerId);
//4. Commit the transaction
getDBTransaction().commit();
//5. Construct a bean to hold new product id and SR id
Result result = new Result();
result.setSvrId(newSR.getSvrId().getSequenceNumber());
result.setProdId(newProd.getProdId().getSequenceNumber());
//6. Return the result
return result;
After adding this code i'm trying to test client program. i'm getting errors like

Jdeveloper 11.1.1.2.0 : Master Detail Using Fragment Error

Hi
When developing a master detail solution, using a page fragment, I have encountered the following issues. I have followed forum articles and My Support solutions with success. The steps I used to create the solution is as follows;
1. Create ADF model project with 2 entities sharing a master detail relatiuonship.
2. Ensure that FK assocation has Behavior property Composition Association checked.
3. Test application module. Create works on both master and detail tables.
4. Create ADF view controller project.
5. Create a new task flow, with page fragments and add page to flow.
6. Add master detail VO to created page fragment.
7. Surround tables with Panel Collection components.
8. Add toolbar and buttons to createinsert into master and detail tables.
9. Add PPR to both tables for refresh when createinsert actions are performed.
10. Create test page.
11. Add task flow as region to page.
12. Run adfc-config.xml
13. Click on createinsert of master table. Capture data.
14. Click on createinsert of detail table.
15. Error stack is generated, JBO-25030 Detail entity with row key null cannot find or invalidate it's owning entity.
I then created a JSF page and added the tables directly onto the page. I successfully created a master and a detail record.
I then checked the Cascade Update Key attributes on the association and added the following code to the master ViewRowImpl class;
@Override
public void setNewRowState(byte state) {
if (state != Row.STATUS_INITIALIZED || getNewRowState() != Row.STATUS_NEW) {
super.setNewRowState(state);
I ran the page containing the region and the following error was generated;
<Utils><buildFacesMessage> ADF: Adding the following JSF error message: Attribute RegionId in Regions is required.
oracle.jbo.AttrValException: JBO-27014: Attribute RegionId in Regions is required.
I then changed auto-submit to true for the PK on the master table. This produced no error, however only the master records PK is committed to the database, other attribute values are ignored and the detail record is not committed.
Regards
Leon.

Insert Record in Master-Detail block

I am using JDev 10.1.2, Struts, ADF and JSP
I have a Master-Detail relationship. As the master table(Course) is browsed , the details(Students) record keep changing. Now I want to insert records to the detail (Students) block alone. I am generating the Students id using Sequence, but I want use the Course Id that is being browsed for the new record inserted. How do I do this.
I used the 'Read Only Dynamic Table' for the Details table and used the create button and forward it to create jsp. When I click on create button, it does go to the create jsp, but the the row is not blank. what do I have to do.
Any help will be appreciated.

Hi Shay,
Thanks for the response. At least I'm getting some response after so long a time.
I'm not sure what are you looking at. But this is what I have.
I have a browseCourse.jsp that displays the courses in the master and students in the detail. I have a create button for the detail, and my code looks like this.
public class BrowseCourseAction extends DataForwardAction
public void onCreate (DataActionContext actionContext)
actionContext.getHttpServletRequest().getSession().setAttribute("type", "create");
if (actionContext.getEventActionBinding() != null)
actionContext.getEventActionBinding().doIt();
actionContext.setActionForward("createstudent");
when the user click on create button it shows the createstudent.jsp. My question is how to set the course id for the new student that is about to be created.
What do I have to do for this?

Displaying a Master Detail Relationship in a Panel Accordion or Tabs

Hi,
Is it possible to display a Master-Detail relationship in a Panel Accordion or Panel Tab or other component that visually divides the display?
Say I have a Department - > Employees master detail relationship and I want each tab in my accordion to represent each
departments and when I clicked the tab, the list of employees associated with that department is displayed.
I am exploring this idea but I cant get to find a resource on how to move forward. I am using JDev 11.1.1.4. Thanks

Hello,
I recently faced the same problem and did not find a clean solution either. So I implemented it a bit more "dirty". :-)
Instead of using the Department > Employee view link, I just created a new view object (say EmployeesFromDept), that has a bind parameter called p_DeptId:
     SELECT ...
     FROM   EMPLOYEES e
     WHERE e.DEPARTMENT_ID = :p_DeptIdThe Data Control of this VO will have an ExecuteWithParams operation that takes the department id as input. Create an action binding in your page definition that binds to this operation, called "RefreshEmployeesForDept":
     <action IterBinding="EmployeesFromDeptIterator" id="RefreshEmployeesForDept"
            InstanceName="MyAMDataControl.EmployeesFromDept"
            DataControl="MyAMDataControl" RequiresUpdateModel="true"
            Action="executeWithParams">
      <NamedData NDName="p_DeptId" NDValue="" NDType="java.lang.String"/>
    </action>In your page, add the current DepartmentId to each showDetailItem using an attribute and add a disclosureListener:
     <af:iterator id="i1" value="#{bindings.Departments.collectionModel}" var="row">
            <af:showDetailItem text="#{row.DepartmentName}" disclosureListener="#{pageFlowScope.myBean.toggleDisclosed}">
               <f:attribute name="currentDepartmentId" value="#{row.DepartmentId}"/>
                          <af:table value="#{bindings.EmployeesFromDept.collectionModel}" var="row"
                      rows="#{bindings.EmployeesFromDept.rangeSize}"
                      emptyText="#{bindings.EmployeesFromDept.viewable ? 'No data to display.' : 'Access Denied.'}"
                      fetchSize="#{bindings.EmployeesFromDept.rangeSize}"
                      rowBandingInterval="0" id="t1">
               //Lots of mapping column here
                    </af:table>
            </af:showDetailItem>
     </af:iterator>Now each showDetailItem that is generated knows the DepartmentId it "belongs to". In the toggleDisclosed(DisclosureEvent disclosureEvent) method, first fetch this attribute, so that you know the dept id of the showDetailItem that was clicked. Next, programmatically call the RefreshEmployeesForDept action binding if the current event is "disclosing the showDetailItem":
     public void toggleDisclosed(DisclosureEvent disclosureEvent) {
          String currentDepartmentId = disclosureEvent.getComponent().getAttributes().get("currentDepartmentId").toString();
          if(disclosureEvent.isExpanded()){
               DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
               OperationBinding operBinding = bindings.getOperationBinding("RefreshEmployeesForDept");
               if(operBinding != null){
                    operBinding.getParamsMap().put("p_DeptId", currentDepartmentId);
                    operBinding.execute();
    }Now, each time a showDetailItem is opened, the bind variable of the iterator belonging to your list of Employees will be refreshed with the correct DepartmentId. Ie the department that the showDetailItem represents.
Hope this helps! If you find a cleaner solution, please let me know. :-)
Regards,
Chris
