Finding Application Module name in read-only view object classes

Hi all,
I have a fairly basic question about finding application module name when we are coding in ViewObject java classes.
I want to know how can I obtain <<application module>> NAME that our current view object is contained in it at run-time. I think there should be a way to find current application module NAME, when we are in ViewObject classes including View Object, View Row or view object definition classes (I've overridden all mentioned classes).
I should notify that since our view object is read-only I may not count on view object's entity classes, coz as you know a read-only view object don't have any entity in it!
So, if you have any idea about finding current application module name in view object java classes please let me know.
Appreciate for your replies,
Nasser

Thanks guy, it was helpful:)
Now i can access application module name through viewObject classes.
But another question is raised...sorry if i m boring:( I promise its the final question ;)
Is there a way to get application module name in an extended version of JboException class?
Thanks again for your reply:)

Read-Only view object won't give me it's row

Hi,
I have a read only view object which when executed has one row in it, but the next method returns null.
this is my code in the AM:
    public Row getPerson() {
        Row row = null;
        ViewObject vo = getPersonsView1();
        vo.setNamedWhereClauseParam("p_login_id", getUserPrincipalName());
        vo.executeQuery();
        System.out.println("rows:" + vo.getEstimatedRowCount());
        if (vo.hasNext())
           row = vo.next();
        return row;
    }and the console log:

but when i debug with a break point in the above method if (vo.hasNext()) returns false.
I have tried doing row = vo.next(); without the if statement, but row still evaluates to null.
The VO returns one record in the BC4J tester and I have this exact method and VO defined in another project and it works there. Tearing my hair out with this one...
Brenden

try RowSetIterator instead,
RowSetIterator it = vo.createRowSetIterator("myIt");
if(it.hasNext())
MyVORowImpl row = (MyVORowImpl)it.next()
//don't forget close the RowSetIterator
I guess you use the VO.next(), but the current row of the VO is the one you get from db, and his next is null...

ADF View Criteria on a Read Only View Object

Hi,
I have created a read only view object using a query. The query consists of analytical functions to fetch the AVG values dynamically.
So far my approach worked fine.
I want the Average values in my query to be calculated dynamically based on the certain view criteria.
But after applying view criteria, my query is formulated as shown below:
SELECT * FROM (SELECT   RECEIVED_YEAR,
           WEEK_NO,
           NO_RECEIVED,
           NO_STARTED,
           ROUND (TO_NUMBER (REPLACE (AVG_HRS_TO_START, ':', '.')),2) AVG_HRS_TO_START,
           ROUND (AVG (TO_NUMBER (REPLACE (AVG_HRS_TO_START, ':', '.'))) OVER (ORDER BY RECEIVED_YEAR),2)              OVERALL_AVG_HRS,
           GOAL_HRS,
           ROUND (AVG (NO_STARTED) OVER (ORDER BY RECEIVED_YEAR), 2) AVG_NO_STARTED,
           ROUND (AVG (NO_RECEIVED) OVER (ORDER BY RECEIVED_YEAR), 2) AVG_NO_RECEIVED
           FROM ORDERS_RCPT_TO_START_VW
ORDER BY RECEIVED_YEAR, WEEK_NO) QRSLT WHERE ( ( ( ( (RECEIVED_YEAR = :RecdYear ) AND (WEEK_NO <= :weekNo ) ) ) ) )
As per this query, it is calculating the Average values first and then applying filter criteria rather than applying the filter criteria and calculating average values.
Please help me on this.

Entity objects are used to update/delete/insert data to the database.
If all your base DB object offers is read then just create a read only view object.

Partial read-only view object. How to make it work?

Hello,
is there a way to have a "partial" read-only view object, where some attributes are based on an EO and some others are extracted directly from a table with no corresponding EO?
On this view-object it should be possible to perform row insertions from an af:table, in a way that, after validation (i.e. a row selection change), the values on the attributes not based on the EO do not get lost, even if they do not have any attributes based on an EO.
On the other hand, if I use fake EO attributes ($none$) for those read-only attributes, their values will not gest lost after validation of the new interted rows, but in this case, when the table is first rendered on the page, the table shows empty values on those items, probably because the EO attributes are empty when the query is performed.
Note that It seems I cannot use Transient attributes where their value is calculated with a SQL statement, since it would mean I would have to perform an heavy SQL statement for every transient attribute.
Is there any other solution, I hope the problem is clear.

That solution does not cover the case where an attributed of one entity used as reference is calculated from a SQL expression with parameters involving the remaining attributes of the same entity.
For example consider a reference-only entity based on a table with one field T(COD). This entity has one more attribute other than COD itself, CALCULATED_VALUE.
How can I bind the attribute CALCULATED_VALUE to a SQL expression which is a function of COD: MyDBPackage.GetValue(COD, :environment), where :environment is bind variable?
The frameowork always give me JBO-exception , asking to specify IN or OUT for the variable.

Adding/deleting rows from a treeTable with a read-only view object

Hello --
I'm getting a JBO-25016 error when I go to delete a row from a treeTable. I want to create the hierarchy from a stored procedure, have the user add and remove nodes without calling back to the database. I will iterate through the tree and see what has changed and made the necessary updates on the database manually.
What is the correct method for adding/removing rows form the UI component?
Thanks!
Tom

Thank you, Amit! That did the trick.

Updatable view and Read only view

Jdev version 11.1.1.6
1. Can we use an updatable view instead of readonly view for LOVs?
2. In my use case, I am having a panel-tabbed component. I create Region in the first tab & create Countries in the second tab. If I use a LOV for Regions based on the read-only view, then the data created & COMMITTED in the first tab is not getting reflected in the LOV in the second tab. But, if I use an updatable view for the Region field's LOV, then the LOV works fine. But, want to know if it is fine to use an updatable view for LOVs.

Quotation from the developer guide
>
Best Practice: When you need to create a read-only view object for
data lookup, you should use the entity-based view object and deselect
the Updatable option in the Entity Objects page of the view object
overview editor.
>
>
View objects can either be related to underlying entity objects or not. When a view
object is related to one or more underlying entity objects the default behavior supports
creating new rows and modifying or removing queried rows. However, the update
feature can be disabled by deselecting Updatable in the overview editor for the
entity-based view object

So the answer for your first question is Yes

Read only view which has an ORDER BY clause

Aim to create a read only view which has an ORDER BY clause
Sample script
CREATE TABLE tab1 (
col1 VARCHAR2(3),
col2 NUMBER
INSERT INTO tab1(col1, col2) VALUES ('ccc', 30);
INSERT INTO tab1(col1, col2) VALUES ('bbb', 20);
INSERT INTO tab1(col1, col2) VALUES ('ddd', 40);
INSERT INTO tab1(col1, col2) VALUES ('aaa', 10);
COMMIT;
-- To creat View
CREATE OR REPLACE VIEW v_tab1
AS
SELECT
col1,
col2
FROM
tab1
ORDER BY
col1
WITH READ ONLY;
I get the following error
WITH READ ONLY
ERROR at line 10:
ORA-00933: SQL command not properly ended
When I comment out the ORDER BY clause, the view is created
Pls let me know how I can create a read only view with ORDER BY clause

Hi,
take a look at the documentation for CREATE VIEW, there is a restriction:
"You cannot specify the ORDER BY clause in the subquery if you also specify the subquery_restriction_clause."

TM Contention and Read Only Views - Toad

I have a case where a select against a view that has the read only option caused TM contention. I realize that the TM can be fixed by indexing the unindexed foreign key which I plan to do. The user only has select privilege so the locking must have come from select for update, but when I checked the query it was a select against a read only view from Toad. Has anyone seen the case where Toad does a select for update behind the scenes which causes locking issues. I am thinking this must be the case otherwise I do not know how a select against a readonly view could hold a lock.

Hi.
I have build some read only views from DB.
All my views are linked.And the Data of each View is shown with " selectOneChoice" or "inputText".
So far so good.
But now my 1.problem.
How can I get the value of the inputText ( coordinates" lat , long ") in a var to use it with a google maps function like
map.addOverlay(createMarker(new GLatLng(lat,long)))
2. problem
how can i change the readout value of the inputText from[i] 51,2456 to 51.2456 for example
Hope for your help!

JBO-25005: Object name 1230_CONTEXT_VO for type View Object is invalid

I am getting JBO 25005 error when I do self appraisal and click cancel or continue button.
We have extended VO and CO on this page, any thoughts what can be the reason behind this error?

Hi NSP,
Check if any personalization been done at responsibility level , that might be causing the issue .

Read a view Object parameter value

can anyone tell me how to read a View Object parameter value from inside a DODML()?
Thanks

Please help us to understand the use case better. Can you please details the scenario? Are you looking for the bind variable value used for querying ?

Accessing view object class (impl) method from bean (or vice versa)

Halo everyone, I am using JDeveloper 11.1.2.1.0
I have a UsersViewImpl class with a method which refresh the user table like below.
public void resetEmployeeSearch() {
removeApplyViewCriteriaName("viewCriteria");
executeQuery();
and I have a UserBean class with a method which reset the search fields values like below.
public void resetInput(ActionEvent actionEvent) {
........RichInputText = input ...
input.setValue("");
AdfFacesContext.getCurrentInstance().addPartialTarget(searchForm);
I would like to implement it in such a way that, once I press a button, both methods will be called.
I have tried to call from bean method using UsersViewImpl vs = new UsersViewImpl ..... which is wrong and wont work.
I have read about doing something like ViewObject vo = am.findViewObject("DeptView1") but I duno how to use it because I cant have a proper example.
Any suggestion on accessing view object class (impl) method from bean (or vice versa)?
Or is there any way to combine both method in the same class ?
Thank you :(

User, if you get class not found exceptions you need to tell us which classes you can't find. The JSFUtils and ADFUtils classes needing some other libraries which should already be part of your Fusion Web Application template (which your adf application should be based on). If you did not use this application template, you may have to add some libraries yourself.
What is the diff of using the ADFUtils and OperationBinding way?
The ADFUtils can get you access to the application module which you then use to call exposed methods on. The disadvantage of doing this is that you have to implement your own exception framework which then handles exceptions thrown by the application module. An other thing is that if you e.g. alter a VO which you use on the page this changes are not seen on the page until you refresh the page. The binding layer does not know about these changes so the iterators (which are used on the page to show the data) are not refreshed and so you don't see the changes.
In general you should avoid using the application modul in a managed bean method and always use the binding layer (OperationBinding) to call methods. This ensures that exceptions are all handled the same way and that changes to the data model are reflected in the GUI.

Which view object classes should be used by managed bean in ViewController?

I just like to find out which java implementation classes created for a view object should be referenced in a managed bean on the UI side.
For my view object InfoVO, I can create the following classes:
View Object class: InfoVOImpl
View Row class: InfoVORowImpl
View Row Client Interface: InfoVORow
View Row Client Class: InfoVORowClient
Currently, I use InfoVOImpl and InfoVORowImpl in my managed bean so that I can use the getter methods conveniently to access the attributes with proper data types.
I am not sure when I should use InfoVORow and InfoVORowClient instead of InfoVORowImpl.
What are the context and reasons for using InfoVORow or InfoVORowClient instead of InfoVORowImpl?

Hi,
all of these are wrong. If you want to access a method exposed on a ViewObjectImpl class, the you expose the method as a clientMethod (or clientInterface) in the Java options for the View Object (or Application Module if the method is on AMImpl). You should avoid using implementation classes directly in the managed bean. If you need to access a View Object, use its interface ViewObject. If you need anything more specific than that, expose a method on the client interface after which you can access it through the binding layer.

Attributes getters/setters not found in view object class

Hi,
I am using JDeveloper 10.1.3.4 and have a question about customizing display hints in the view object.
In my application that is to be used by both the students and the administrative staff, I generated both the entity object and view objects for a table from the database. Some of the attributes need customized display format. For example, social security numbers in the datatable is 123456789. For the student users it needs to be displayed in the xxx-xx-6789 format. For staff users, it needs to be displayed in the 123-45-6789 format.
Therefore I create two view objects from the same entity object, one for students and one for staff, each to have its own display format. To put the customization code in the attributes' getter methods, however, I found that in the view object class files the getter methods are not there. The entity object class file has the getters; however if customization is done there I will not have two different formats.
What should for the getters to become available in the object class file so that I can customize them?
Thanks a lot for helping!
Newman

Newman,
Attribute getters would be on the view object ROW class.
