ADF: CREATING DEPENDENT LOV

Hi Everyone,
i have created two LOVs just to list the values(2 separate VOs but both are from same table).
Now i want to make 2nd lov values dependent on first lov.
how can i create dependant lov?
plz give detailed simple steps for dependant lov creation as im new to this ADF field.
Thanks in advance.
Regards,
RAJA.

Sorry, but as far as I can tell the samples are doing exactly what you want. If not do should be able to adapt the samples to your needs.
In general here on this forum we only point you in the right direction...
From the information you gave so far the samples should get you going.

How to create dependent LOVs

Hi all,
Does anyone know how I can create a LOV with values dependent on the LOV value selected from the one above when defining a custom item?
For example, I have defined a custom item which has 2 attributes with 2 LOVs:
attribute1 - LOV1
attribute2 - LOV2
I would like to populate LOV2 depending on what value the user selects in LOV1, is this possible?
Please advise.
Thanks.

Hi,
You can create dependant lovs and use them only in the forms component. Here is how you create dependant lovs
lov1
select empno,ename
where deptno = :dept
Creating a LOV with a bind variable makes it a dependant lov. In forms you should map the bind variable to one of the form columns.
Thanks,
Sharmila

Issue in creating dependent LOV

Hi,
I am creating a dependentLOV Items.
1) Selecting Project Number.
2) List of Tasks in the selected Projects.
when ever user selects particular project number in 1st LOV item the list of tasks assossiated to that project should be
populated in 2 nd LOV.
Can any one suggest.
Regards,
Krishna

Hi Reetesh,
I am unable to create dependency.
VO Querys of Projects and Tasks
Projects VO
select a.SEGMENT1,a.NAME,a.PROJECT_ID
from pa_projects_all a
TasksVO
select a.TASK_NUMBER,a.TASK_NAME,a.PROJECT_ID
from pa_tasks a
I am explaing the steps I have done just show where I met error.
1) Create ProjectsLOVRN (projectno,name,projectId) TasksLOVRN (TaskNumber,Name,ProjectId)
2) Create 2 LOV Items Projects and Tasks
3)In Projects LOV I created 2 LOV Maps which returns Project No and Project Id
4)In Tasks LOV created 2 LOV Maps as you suggested
in first map LOV Region Item TasksLOVRN(TaskNumber)
Criteria Item returned ProjectId from ProjectsLOVRN
Required and Programatic Query is set to true
for crieteria item will be the Project LOv Item how can I select an ProjectsLOV Item in TasksLOV
in second map
LOV Region Item TasksLOVRN(TaskNumber)
return Item LOV ItemTask
While running page At header I am getting an error
Error
Developer Mode Exception : Lov Input should by default be the queryable criteria and Result.
Please suggest where exactly Iam making mistake to create Dependent LOV

How to create dependent LOV based on procedure?

Hi,
There are two dependent list of values which i need to create. There is an existing package which returns the list.
Can you suggest which approach should i use to create these list. Should i execute the procedure in the IMPL class and then bind the list to the transient VO or should i create a table which stores the result of the package and then use query based VO.
After selecting the list values and clicking on GO it should generate a table too based on that list values selected.
Which approach is correct? If any other approach then please mention.
And can you explain how do we bind the list to the transient VO for the first approach if thats the correct approach.
Thanks in advance

Hi,
I would build programmatic view objects for both of them (I usually also prefer having the View Objects based on a custom entity object). The tricky part is that you need to override the default View Criteria behavior (as you have to detect the view criteria, its condition and then map it to the stored procedure call)
Here are some links that will help:

Dependent LOVs in Discoverer Admin

Hi All,
Can we create dependent LOVs in Discoverer. If yes can anyone throw some light that.
regards,
gt1982

Well, let me try to clarify what Tamir said. I think you probably will need to do some setup work in Administrator. I am assuming that you want to do something like this in a worksheet - The user first clicks the LOV indicator on the Region parameter and picks a region from the Region LOV (say they pick the East region value), and then based on that region value, when they click on the City parameter LOV icon, the list of cities they see is filtered so that they only see cities in the East region (say New York City and Boston). To do this correctly in a worksheet, you need to define an Item Hierarchary in Discoverer Administrator. The two parameters must have some kind of relationship in the database to make this work.
Then once you have the item hierarchy defined, the rest of your work is in Discoverer Plus. You create the first parameter in the worksheet. In my example, you would create the Region parameter first. Next you would create your second parameter (in my example, that would be the City parameter). When creating the second parameter, that is when that section on the parameter window ("Do you want to filter the list of values for this parameter") comes into play. You will want to select the "Filter the list of values based on the selected conditions" option, and then find the condition name (for the Region parameter created condition) and select that condition. The term Oracle uses for this is "Cascading Parameters". So if you search on that term in the Discoverer Plus user guide, that will give you more information on this process.
Now, you do have to be careful. Ideally the folder with the relationship between the two parameters is based on a master table, not a detail table. If based on a detail table, you can run into performance problems when clicking on the LOV icon for the second parameter. The system may take forever to try to build that second LOV.
But the process does work. I have used it a couple of times.
Hope this helps a bit. Good luck.

How to create depedent lov using groovy functionality

Hi,
My requirement is need to create dependent LOV on form like, when ever user selects merchant_number, remaining merchant details should default, till now i am doing with valuechange listener. now i wanted to do on vo itself using groovy functionality. i have created merchant VO which is returning 4 values, merchant_number,name,phone,address. i have created view criteria with a bind variable.
In my main vo i have created LOV for merchant_number. added the merchant vo as view accessor and set the bind variable value as merchant number. and with the merchant_name i am trying to setting as XxwfsMerchantDetailsLOV1.getMerchantName(). i am getting error like
Exception in thread "AWT-EventQueue-0" oracle.jbo.JboException: JBO-29000: Unexpected exception caught: groovy.lang.MissingMethodException, msg=No signature of method: oracle.jbo.server.ViewRowSetImpl.getMerchantName() is applicable for argument types: () values: []

Can't create multiple dependent LOVs from the same bind variable

Hi all,
I'm having difficulty creating multiple dependent LOVs from queries based on the same bind variable in my JSF application (JDev 10.1.3.1). Basically I have a static LOV in a af:selectOneChoice component from which users select a value which then becomes the bind variable value for two separate queries that generate two different dependent LOV. Having developed the code along the lines of Steve Muench 's blog (http://radio.weblogs.com/0118231/2006/04/03.html#a685), the first dependent LOV works really well. The first dynamic LOV gets refreshed whenever the list from the static LOV changes, and I can execute other queries based on the values selected.
The problem arises when I want to create the second dynamic/dependent LOV that has the same bind variable based on the same selected value from the static LOV. Here I would also like the functionality whereby the second dynamic LOV is also refreshed after the selected value in the static LOV changes. Thinking that all I had to do was replicate the methodology used in creating the first dependent LOV, I created the second iterator, invokeAction and other binding components in the PageDef. The executable section now looks like the following:
<iterator id="SelectStaticQueryViewObjIterator"
              Binds="SelectStaticQueryViewObj" RangeSize="-1"
              DataControl="DMSApplicationModule1DataControl"/>
<invokeAction id="refreshDynamicQuery1BindParameter"
              Binds="ExecuteWithParams1" Refresh="prepareModel"
              RefreshCondition="#{empty requestScope.VariableChanged}"/>
<iterator id="SelectDynamicQuery1ViewObjIterator"
              Binds="SelectDynamicQuery1ViewObj" RangeSize="-1"
              DataControl="DMSApplicationModule1DataControl"/>
<invokeAction id="refreshDynamicQuery2BindParameter"
              Binds="ExecuteWithParams2" Refresh="prepareModel"
              RefreshCondition="#{empty requestScope.VariableChanged}"/>
<iterator id="SelectDynamicQuery2ViewObjIterator"
              Binds="SelectDynamicQuery2ViewObj" RangeSize="-1"
              DataControl="DMSApplicationModule1DataControl"/>I now have a problem whereby everytime I change the value of the static LOV, multiple HTML components for the same ADF component are being generated (the LOVs are refreshed via PPR). The surprising thing is that this duplicating behaviour applies to all ADF components listed after the first dynamic LOV in the *.jspx source. For example, I have a <af:outputText="Test Text"/> component created after the first dynamic LOV. Each time the value in the static LOV changes, a duplicate HTML component is created. This also applies to the 'related' second dynamic LOV which is bound to a af:selectOneChoice component - multiple dropdown lists are created. I've checked with the browser's Page Source and there are actually multiple html components being generated with their own unique ADF-generated IDs. I've tried all different options for the Referesh and RefreshCondition attibutes in the second invokeAction element but nothing seems to eliminate this issue.
Any suggestions about how I might create multiple dependent LOVs from the same bind variable that get refreshed when the selected value changes would be greatly appreciated.
Thanks
George

Hi all,
Just updating the thread on how I've overcome this issue. As it stood the manner in which I was trying to solve my use case, as described above, was creating an absolute mess. Then with a blank sheet of paper I quickly realised that a much simpler solution would be to create a whole series of master-detail VOs and build my components around them. Thankfully I haven't had any issues going down this path as yet.
Cheers

BUG ? : ADF creating extra VO instance using bind variables in a LOV query

ADF 11.1.1.1.0
After "playing around" with bind variables Setting bind variables in view objects for LOV I've come across something strange that I've reproduce using the HR schema and tables Employees and Departments. Its a bit long but here goes :
Using the HR schema tables departments and employeesI'm trying to create a LOV (selectOneChoice) for the
employee department, the LOV having a bind variable that limits the values returned in this case returning only DepartmentId = 50
I've create a VO lovDepartment (not based on an EO) with the following query :
SELECT Departments.DEPARTMENT_ID,
       Departments.DEPARTMENT_NAME,
       Departments.MANAGER_ID,
       Departments.LOCATION_ID
FROM DEPARTMENTS Departments
where DEPARTMENT_ID = :pDeptIdA LOV has been defined on the DepartmentId attribute of the EmployeesView.
The lovDepartmentImpl overrides the executeQueryForCollection to set the bind variable value.
    @Override
    protected void executeQueryForCollection(Object object, Object[] object2,
                                             int i) {
        setNamedWhereClauseParam("pDeptId", "50");
        super.executeQueryForCollection(object, object2, i);
    }When using an ADF form to create a new employee the DepartmentId lov is empty.
Enabling SQL tracing shows the following :
[370] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1_0 ViewRowSetImpl.doSetWhereClause(-1, pDeptId, null)
[371] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1_0 ViewRowSetImpl.execute caused params to be "un"changed
[372] Column count: 4
[373] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1_0 ViewRowSetImpl.doSetWhereClause(-1, pDeptId, null)
[374] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1 ViewRowSetImpl.setNamedWhereClauseParam(pDeptId, 50)
[375] ViewObject: _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1 Created new QUERY statement
[376] _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1>#q computed SQLStmtBufLen: 235, actual=195, storing=225
[377] SELECT Departments.DEPARTMENT_ID,
       Departments.DEPARTMENT_NAME,
       Departments.MANAGER_ID,
       Departments.LOCATION_ID
FROM DEPARTMENTS Departments
where DEPARTMENT_ID = :pDeptId
[378] Bind params for ViewObject: _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1
[379] For RowSet : _LOCAL_VIEW_USAGE_model_EmployeesView_lovDepartment1_0
[380] Binding null of type 12 for "pDeptId"
[381] No Resource Bundle found but null value id:LOV_DepartmentId_LOVUIHints_NullValueId is defined in an ListBinding Definition.It would seem that 2 lovDepartment instances are used one at line 370 LOCALVIEW_USAGE_model_EmployeesView_lovDepartment1_0
and one at line 374 LOCALVIEW_USAGE_model_EmployeesView_lovDepartment1
The one at line 374 LOCALVIEW_USAGE_model_EmployeesView_lovDepartment1 gets the variable bound at line 374
however LOCALVIEW_USAGE_model_EmployeesView_lovDepartment1_0 gets a null value and would explain the empty LOV
Can anybody explain what is happening here ? (and how to use bind variables in LOV queries)
Regards
Paul

I've now tried all types of LOV from ChoiceList to Radio groupe by testing the application module - none of them work.....
Edited by: Paul (MITsa) on 14-Jul-2009 22:52

when you rinvoke executeQueryForCollection the bind variables are allready set and they exist in Object[] object2 method parameters.
in order to change them you need something like:
private void changeGenericBindVariable(Object[] params, String paramName, Object paramValue) {
for (int i = 0; i < params.length; i++) {
if (paramName.equals(((Object[])params)[0].toString()))
((Object[])params[i])[1] = paramValue;
* executeQueryForCollection - overridden for custom java data source support.
protected void executeQueryForCollection(Object qc, Object[] params,
int noUserParams) {
changeGenericBindVariable(params, "pDeptId", "50")
super.executeQueryForCollection(object, object2, i);
But its better to set bind variables before you executeQueryForCollection. like when you invoke LOV.
For cascading LOVs and the problems i have check:

ADF Desktop Integration: How do I use dependent LOVs in Table Components?

Hi,
I have a table component that has a series of dependent LOVs. Now, while I understand that ADFdi allows for LOVs to be chained together by dependency, what I don't understand is how to get the child values to change based on a selection of a parent value. Is there a method binding I missed? Or is there some other mechanism I'm not seeing in the documentations? Hope someone can help shed some light on it - Google is darkness. Thanks.
Cheers,

Dependant LOV on Search Field

Hi,
I am a newbie using ADF 11g. I am trying to create a Search page which takes 2 parameters.
1st Parameter is the Country LOV
2nd Parameter is the City LOV which is dependant on the 1st Parameter
I have done the below steps but no with no positive results.
1. The SearchVO is like this
select * from Dept
where
country = :pCountry and
city = :pCity
2. I create search in the following way
- Pull the ExecutewithParams as Search button on the screen
- Pull the table as table results
3. Process of creating the ParentLov.
- Pull the Parameter under the VO-> execute with Country params on to the screen as Select Choice Box
- Slect the CountryVO in the LOV as the View Object select required fields to be available on LOV and map with just Country Name Parameter
4. Process of creating the ChildLov.
- Pull the Parameter under the VO-> execute with City params on to the screen as Select Choice Box
- Slect the CityVO in the LOV as the View Object select required fields to be available on LOV and map with just CityNameParameter
5. Go to Page defintions,
- create a binding that maps the CityVO bind variable with the CountryName Parameter input value given in the step 3
- create a invoke action for that binding and place it before CityVO Iterator
6. I have set Partial trigger and autosubmit correctly for child and parent
Even after all this attemp I am not able to see the child getting populated. Child shows blank values
If I create a LOV for the View Object attributes that works but for Bind Variables, It simply doesnt..
Can somebdoy help me.. Most of the dependant LOV post talk abt VO attribute LOV but not abt a variable based LOV... URGENT respone/help required.
Thanks,

How to link bindvariable with ViewAccessor to make it ADF Input with LOV

I have create a view object by sql query in which i have two bind variables. I want to create a search form by these two bind variables as search criteria so i drag "Execute with Params" operation from Viewobject Data Control to a jspx page as a ADF Search Form. Now i want to create these two parameters as a ADF Input LOV so i changed control type in view Object for these two bind variables but i am not able to fine how to attach viewaccessor with it for data source. Kindly help me.

Hi,
in this case - if th ebind variables are not based on an attribute that has a LOV defined - you replace the components in the input form. To do this, remove the input text field and drag the attribute (the argument) onto the form again. Choose select one choice to create a drop down and then map it to the VO that providesthe values. Note that this doesn't create a LOV binding so you use lists for this.

Mandatory fields on the same page with dependent LOVs

Hi,
I am working on an ADF-BC application using JDeveloper 10.1.3.4
I have an ADF Creation form with dependent LOVs and while implementing dependent LOVs we set the autoSubmit property of the selectOneChoiceListBox as true.
If I have some mandatory fields on the same page then because of the autoSubmit property set as true whenever I select a value in the list the page gets submitted and the mandatory fields give an error that the values are required therefore I had to remove the mandatory fields.
I tried using f:subview but even that dint serve the purpose because what I want is something like partialSubmit so that my mandatory fields do no give an error when I select a value in the list.
Can somebody help me on this, how to have a dependent list and mandatory fields on the same page.
P.S: It is very crucial for my application
Thanks,
Raksha

Hello,
This bug has been around since 10.1.3, its even still present in Trinidad and now in 11.
One of the ways to avoid is to make your fields use:
showRequired="true"instead of
required="true"I have not found a decent way to avoid this in general.
My idea was that this shiould be possible with a phaselistener and determine if this is a partial page event instead of a normal submit, but this didnt work.
