ADF BC: LOV in view object and af:table

Using JDev 11g PS2
I have a few question about the use of LOV's in BC.
Let's take the HR schema as an example.
Suppose i am building a basic CRUD operation for the employee table. The employee has a FK to the department, job and manager table.
I have build a view that only uses the Employee entity. I have also defined a LOV for the departmentId and jobId.
This is all working quiet well when i put it into a form.
When i am adding a read only table to my page, the departmentId and jobId are shown as a number instead of their corresponding value for the department and jobs table.
The question i am having, what is the best practice for solving this? Is there a way to tell the output text to show the value of the LOV instead of the actual ID? Or do i need to modify my VO and add the department and jobs view to my Employee view so i can add the departmentName and jobTitle column to my employee VO?
I also notice that when i enable the filter on my table, it does not show my LOV for the department and job column... How can i enable that?

The departmentId and jobId are shown as a number instead of their corresponding value for the department and jobs table1) What ADF Faces components do you use for the Department ID and Job ID in the table?
2) What Control Type is chosen for these VO attributes on "Control Hints" page of VO attribute definition dialog (Default, Choice List, Combo Box, Input Text With LOV, etc.)?
The generated table/tree binding does not specify the type of corresponding attribute bindings (have a look at the generated PageDef). The types of these attribute bindings (and also the types of the UI components inside corresponding <af:column>s) depend on the values of Control Type. If you use Choice Lists, then Department Name and Job Name should be displayed (if your LOV configurations specify them as displayed attributes). If you use "Input Text With LOV", then IDs should be displayed. I am not sure what should be displayed if "Combo Box" is specified, I suspect that IDs would be displayed.
Do i need to modify my VO and add the department and jobs view to my Employee view so i can add the departmentName and jobTitle column to my employee VOIf you use Choice List and if the LOV has parameters (from values of another VO attributes), then the Choice List query will be executed once for each VO row (if the parameter values are different for the different rows), so the performance will be slow. It is recommended to avoid Choice Lists in such cases but to include the corresponding "name/descrription" attributes in the VO query. If the LOV's query does not depend on any parameters and you use Choice List, then the query will be executed once at page load and then it will be reused from the VO cache.
When i enable the filter on my table, it does not show my LOV for the department and job column... How can i enable that?Table filter fields are text fields by default. You are able to override default filter fields (for example, with <af:inputListOfValues>) by using <f:facet name="filter"> within corresponding <af:column>. Just specify the necessary input component(s) within this facet.

How to create dynamic View Object and Dynamic Table

Dear ll
I want to create a dynamic view object and display the output in a dynamic table on the page.
I am using Jdeveloper 12c "Studio Edition Version 12.1.2.0.0"
This what I did:
1- I created a read only view object with this query "Select sysdate from dual"
2- I added this View object to the application module
3- I created a new method that change the query of this View object at runtime
    public void changeVoQuery(String dbViewName) {
        String sqlstm = "Select * From " + dbViewName;
        ViewObject dynamicVo = this.findViewObject("DynamicVo");
        if (dynamicVo != null) {
            dynamicVo.remove();
        dynamicVo = this.createViewObjectFromQueryStmt("DynamicVo", sqlstm);
        dynamicVo.executeQuery();
4- I run the application module for testing the method and I passed "Scott.Emp" as a parameter and the result was Success
5- Now I want to show the result of the view on the page, so I draged and dropped the method from the data control as a parameter form
6- I dragged and dropped the view Object "DynamicVo" as a table and I choose "generate Column Dynamically at runtime". This is the page source

Have you seen Shay's video https://blogs.oracle.com/shay/entry/adf_faces_dynamic_tags_-_for_a
All you have to do is to use the dynamic table to get your result.

Can Designer generate ADF Entity Objects, View Objects and Apps Module ?

Hi all,
On what way can Designer integrate with JDeveloper (+ ADF) ?
Can Designer generate ADF Entity Objects, View Objects and Apps Module ?
Thank you for your help,
xtanto

Designer itself has no direct integration with JDeveloper. However, there are three options. First of all, you can get a JDeveloper extension (download this separately) that lets you create a Connection to a Designer repository. From that Connection you can find modules that you defined in Designer and generate Entity and View objects for the tables and columns that you used in those modules, and an Application Module. It does not create JSPs or other user interface objects.
Another option is to buy JHeadstart from Oracle. This contains a set of code generators and ADF extensions that include an ability to get information from a Designer repository. JHeadstart works fine for non-Designer users too, but was built by the same people who wrote Designer Headstart - they know the repository API intimately.
The third option is to download Oracle Designer Extension Builder (ODEB) which was just recently made available. This is a product of a collaboration between Designer users from the Oracle Development Tools Users Group (ODTUG) and Oracle to extend the capabilities of Designer with user written tools and utilities. You could use ODEB to write your own generators for ADF Business Components. Or you could wait and see if someone else in the user community does this. I hope that you or whoever does such a generator will be willing to share it with us all.

Iterating through master view objects and child view objects in same page

I am working on a project using ADF UIX and Business Components.
I have an application module with two view objects one the master view object and the second the detail object. They are related via a view link.
I would like to iterate through the master view objects displaying a customer name as bold text and then below each customer name I'd like to display the detail records in a table via the detail view object i.e. a seprate table for each customer.
Is this possible - I haven't had much luck!?
Thanks in advance.

That's because
$(".ms-vb2 a").
is bringing back all the pieces that have that class with an anchor on the whole page, not just the ones in the .ms-wpContentDivSpace
I don't know the exact syntax, but I think you need to iterate through all the '.ms_vb2 a' items as well - there are multiple ones, and do something like this inside your other grouping
$(".ms-vb2 a").each(function(index) {
    var val=$(this).html();
   var val2=val.replace(/_/g," ")
   $(this).html(val2);
That's not quite right but maybe that will help.

SQL Loader Constraints with Column Objects and Nested Tables

I am working on loading a Table that (god forbid) contains columns, column objects, and nested tables (which contains several depth of column objects). My question is does SQL Loader have a hidding undocumented feature where it states how the column objects must be grouped in refereneced to the nested tables within the loader file? I can load the various column objects, and nested tables fine right now, however, I am loading them all in strange and insane order. Can anyone answer this question? Thanks.

I just noticed that my email is wrong. If you can help, plese send email to [email protected]

I've been reading about something similar here
BC4J Master-Detail-Detail
but I am still unsure of what the problem is.
Thanks in advance.

Dynamic view object and LOV

Here's the problem I've encountered. I need to create an input LOV, where list is taken from dynamically created view object (it is created using createViewObjectFromQueryStmt; query may be different, but it always has 3 columns with fixed names - that's the rule). The problem is quite similar to that described here: {thread:id=935344}
I've tried to create a "stub" LOV with a query like
select 1 ID, 1 RESULTVALUE, 'dynamic' SNAME from dual(all the queries will have 3 columns with names ID, RESULTVALUE and SNAME) and then changing it's query by using something like this
    public void recreateDynamicViewObject(String newSQL) {
        ApplicationModule am = ADFUtils.getApplicationModuleForDataControl(DATACONTROL);
        if (am.findViewObject(DYNAMIC_VO_NAME) != null)
            am.findViewObject(DYNAMIC_VO_NAME).remove();
        ViewObject vo = am.createViewObjectFromQueryStmt(DYNAMIC_VO_NAME,newSQL);
        vo.executeQuery();
    }but it didn't work (with the same results as it was mentioned in the post I've given reference to - the VO changes, but the new rows are not displayed).
My question is almost the same: is it possible to use a dynamically created VO in LOV? The option of creating a VO for each query is unacceptable in my case, because these queries in fact are created by end users, and there can be any number of these queries.
In case it is important - I use JDeveloper 11.1.1.2.0.

I am also looking for a similar solution.
Actually it works partially.
I have a created a permanent View Object with a dummy query and in the run time I am replacing the View Object query in the ProcessRequest in CO.
My problem is when you click on the LOV it works fine with the changed query results, but when I clicked again on the LOV, it shows the the dummy query results which I gave it in the VO.
Here is my AM method which is called in the CO.
BOSS_Parameter1_LOV_VOImpl parameterVO =
getBOSS_Parameter1_LOV_VO1();
parameterVO.clearCache();
parameterVO.executeQuery();
System.out.println(parameterVO.getQuery());
parameterVO.setWhereClause(null);
parameterVO.setWhereClauseParams(null);
parameterVO.setQuery(lovQuery); // this the dynamic query
parameterVO.setWhereClause(null);
System.out.println(parameterVO.getQuery());
Even though its showing the changed query in the getQuery, the LOV is not refreshed.
I am also changing the Query of the View Object in the ProcessFormRequest
if (pageContext.isLovEvent() || pageContext.getParameter(EVENT_PARAM).equals("lovPrepare")) {
call the above mentioned method in the AM.
But, still it doesn't work.
Any tips will be appreciated.
Thanks,

How to retrieve rows in view object and display on UI

Hi All,
I am new to ADF. i am using jdeveloper11.1.1.5.0 . Here is my scenario.
In my AM i have a view object say EmployeeVo. on empVo i am performing setRangeStart and setRangeSize.
empVo .setRangeStart(2);
empVo .setRangeSize(2);
Rows[] rows=empVo .getAllRowsInRange();
so from the above statement will get two rows from the empVo object. Now i have to display these rows in UI in the form of af:table.
Can anyone suggest how to acheive this.
Thanks in advance.

<af:table value="#{Bean.listValue}" var="row" />
//refer rows like
<af:column>
<af:inputText value="#{row.description}" />
</af:column>
List listValue = new ArrayList();
//getter setter of listValue
//bean constructor
retrieve the rows from the AM methodthe above step is very crude hope you understand the steps

How to create a view object and attach with extended AM

Hi,
I tried to create new vo and attach this vo with the extended AM. But it is throwing error like 'PC.NAME : invalid identifier' (Actually this PC.NAME is exiting one).
Now i want to know how to create a view object similar like seeded one but with one additional condition in the where clause.
It is possible though extension, but i want to create two view object similar like seeded one, one with some other condition in the where clause
and another one with some other condition.
So for my requirement, i'll extend one VO and i'll add my condition but how to do it for second condition.
But i want same seeded VO with two different condition.
Any suggestions please,
SAN

SAN,
There is no need to attach the newly created VO with extended AM. You need to attach the same with the standard AM.

View link creation on two view objects, and both view objects are populated program(not from sql)

I have master and detail VO , both views data is loaded in program. Now for show/hide feature, I create View Link Object and using one element from both child and master VO , View Link Object created properly.
But I can not able to add that view link object into AM.
Now because of that , I cannot say what is a instance name of that view link object.
Hence getting following error -- Invalid or missing view link. Please attach view link with the bean.
Please can you provide some directions.

Expert mode query in View objects and appended where clause

My company is Oracle Member Partner and we are developing enterprise web applications using Oracle database and BC4J.
I have the following problem...
When I enable EXPERT MODE option in View Object I have trouble appending to query statement in my client code.
I need expert mode because I must use "SELECT DISTINCT" insted of "SELECT" in my query.
It looks something like this:
viewObject.setWhereClause("CLA_ID = " + claId);
viewObject.executeQuery();
SQL query from View Object becomes sub-query and fails to execute:
select * from (original view object query) where (... appended where clause)
Order by part of the query causes sql errors because original query is now sub-query.
Is there any way around this?

I tried creating an expert mode SQL query:
SELECT DISTINCT EMPNO, ENAME FROM EMP.
Then at runtime I do:
vo.setWhereClause("ENAME LIKE '%'||?||'%');
vo.setWhereClauseParam(0,'A');.
and this works fine. The trick is that since expert-mode view objects get wrapped as inline views (to allow runtime appending of WHERE clause, actually), you need to select any column in the select statement to which you want to later refer in a dynamically-appended where clause.
If you want to prevent the inline-view wrapping, you can write the following code in your view object's ViewObjectImpl subclass to force the VO to NOT be treated as an expert-mode SQL VO.
// Goes in your view object impl subclass
public void create() {
     // Force this VO to NOT be treated as an expert-mode SQL, so that
     // its query does not get wrapped as an inline view.
     getViewDef().setFullSql(false);
}I used this trick above to create an expert mode query like:
SELECT DISTINCT deptno FROM empand then at runtime I add a dynamic where clause that refers to a column
in EMP that is not in the select list like this:
    ViewObject vo = am.findViewObject("View1");
    vo.setWhereClause("ename like '%A%'");
    vo.executeQuery();
    System.out.println(vo.first().getAttribute(0));and this causes the query to come out as:
SELECT DISTINCT deptno FROM emp WHERE ename like '%A%'.
instead of:
SELECT * FROM (SELECT DISTINCT deptno FROM emp) QRSLT WHERE ename like '%A%'which would cause an error due to the fact that ename is not in the select list of the original (wrapped, inline) query.

JSP, View Object and ? parameter

I have a view object that uses a ? type parameter in its query. The use ? type parameter checkbox has been marked in the view and the view compiles successfully.
Now this view is being used by the Data Web bean JS Tree Browser in a JSP page.
The JSP code
<jsp:useBean class="oracle.jbo.html.databeans.JSTreeBrowser" id="roleMenuTree" scope="request" >
<%
roleMenuTree.setDepthLevel(6);
roleMenuTree.setReleaseApplicationResources(false);
roleMenuTree.setDisplayAttributes("Name");
roleMenuTree.initialize(pageContext,"Tasksys_TasksysAppModule.MenuTreeView");
Object x[] = new Object[1];
x[0] = "tasksys";
roleMenuTree.getRowSet().getViewObject().setWhereClauseParams(x);
roleMenuTree.getRowSet().getViewObject().executeQuery();
roleMenuTree.render();
%>
</jsp:useBean>
But I end up getting the following error. WHY ?
Error: 500

You need to prepare the query using the setWhereClauseParams(x) call, before you initialize your data web bean. Otherwise, if you call the methods after you initialize your web bean, the context has already been set and the error occurs.
You should insert another data web bean into your page somewhere at the top and use it to setup your query and create a view object. You should remove this bean's Render() method since you are only interested in the Initialize() method here. Add your code to prepare the query and create the view object.
Then when your JS Tree Browser executes, it will be able to call getRowSet() on the View Object you created already.

How to create LOV on view object with itself

Hi
My scenario is that I have COUNTRY table with columns Country_Code and Country_Name.
I need to display the Country_Name as selectonechoice. User will select some country name and then I should get the Country_Code associated with the selected Country_Name in Managed bean.
Could you please suggest how to achieve this?
Regards,
Vinod

Hi
My English isn't very good.
create a view obj on COUNTRY table then from Data Control drag&drop view obj as a Single Selection and then select Adf Select One Choice and from there you can select which attribute to display.
in managed bean you can get the Country_Code from the below code:
DCBindingContainer dcBindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iteratorRow =
(DCIteratorBinding)dcBindings.get("iterator name for view obj");
Row row = iteratorRow.getCurrentRow();
System.out.println("row[]=" + row.getAttribute(0));

ADF Passing Parameter to View Object

I created a view object that has, as part of it's where clause, ":1 = field". :1 can also be replaced with ?. I added this Object to my AppModule and was wondering how to bind that value from a "web tier" object. (I'm new to the "whizzy wig" development, maybe this isn't possible) thanks for any help

Master - Detail for View Object and Javabean

I have a table which data comes from VO (database, let's say from table A). This table has table Id, name, and processId. I also created a second table below the first table, which data comes from a javabean (data from non-DB source). I created a data control from this bean, which in turn I created the second table.
What I am trying to achieve is that when a user select a row from the first table, I would like the second table is refreshed based on processId value of the row selected from the first table.
Would you share how to achieve this?
Thanks.

Hi Shay,
I created the javabean with an exposed method with parameter. I created the parameter form and a table that PPR to the form and each component in it (just to be sure). Unfortunately, the table shows nothing after pressing the button.
I ended up creating custom row selection listener and for each selection, then in backing bean, I pass the value from selected record to the VO (data from DB table) and execute the query. This works fine when a user select a record.
Unfortunately, on page load, the query is also execute and show a record that has nothing to do with the main table. I set the table not to have any row selected on page load (this works), and try to set refresh Condition to #{!adfFacesContext.initialRender} on the VO (data from DB table) to avoid query on load (this doesn't work). No row is selected on page load, but the query is still running and show the first record of VO query (nothing to do with the master table).
Any other suggestion?
Thanks.
