Calling view criteria in a method call

Hello. I'm trying to execute a query with view criteria via a method call. Is this possible? I'm trying to keep my view objects generic and not have specific bind variables.
Thanks!

If you want to call the VC from a method you can do something like this.
public void QueryEmp () {
findViewObject("EmpView1").applyViewCriteria(findViewObject("EmpView1").getViewCriteriaManager().getViewCriteria("AllClerk"));
findViewObject("EmpView1").executeQuery();
That any use to you??

Looking for hook into a mb method on page load of jsff with auto query on view criteria.

Hello,
I have a View Criteria that is set to Query Automatically (showing data to match today's date). The target table has a detail table and there is a control that shows parsed XML from the current row in the detail table into a table that I build dynamically. The main table and the detail table show the proper data on page load but the table for the parsed XML is empty. The dynamic table is bound to a managed bean where the parsing is done and data is created. I have the control refreshing properly on a row change of the main and detail tables and on a queryListener for the view criteria.
This is for a jsff page. I have been trying a bunch of approaches with no success. The detail table has a ppr to the main table and the query. I am looking some event on either the query, the main table or the detail table where I can make a call to my managed bean to parse the XML, build the table and refresh the control. I have an attribute binding to the XML data (when I placed it in a control as plane XML it refreshed properly). I only need this on initial page load or first time the tables are populated, I have the other use cases covered.

Thank you

ok but where?
i have read a topic about "setRefreshOption", but i need a component to execute it.
i have read a topic about a false criteria (1=2), and when i want search, i remove it, but again, i need a component to execute it.
i have read a topic about ${adfFacesContext.postback == true} to write into iterator proeprty, but i haven't this view into my appmodule.
i'm really sorry, but please, can you explain me a little ?

Using view criteria.

Hi. I'm new to adf and my english is poor so be patient with me, thanks in advance for that.
To build a serch form based on a view that was configured to use a bind variable I simply drop the Executewithparams operation and build a adf parameters form.
There is any way to do the same think (or something like this) with a view criteria. I tried to put an instance of the view and customize it with a view criteria that used a bind-variable in the application model. But using Executewithparams didn't work and I don't know what method I should call ?

Thanks for the answer, you are right I already tried this, but I wanted an input box + a button because the idea is: If the search returns only one result then you get a result page directly, but if there are many results then you get a page to choose one of them. I did this with a task-flow: one view for the search-panel then a router and a view for the choose-one-page (I haven't got time to test it completely but it seems to work).
There is a way to do this with the quick query component ?
Thanks [email protected]

View Criteria

Hi,
I am new to adf exploring by doing one POC ,my requirement is, i need to call the application module impl through backing bean to search based on 2 inputs form DB table and the result set i need to store into session.
for this i wrote view criteria and how to call
I need to get through backing bean
this i wrote in VOImpl class under one method which i am calling from Application module impl class
Proj_name and PA_name are bind variables of View criteria in VOimpl class(Generated View Object class)
ViewCriteria vc =getViewCriteria("ProjectViewObjVOCriteria");
setPA_name(ProjName);
setProj_name(PANumber);
applyViewCriteria(vc);
executeQuery();
error :oracle.jbo.InvalidObjAccessException: JBO-25036: An invalid object operation was invoked on type View Object with name ProjectViewObjVOImpl_19 at first line( setPA_name(ProjName);) setting in above stmts
is it correct what i m doing? if not can anyone guide me in this

Including additional where clause conditions to view criteria dynamically

Hi,
We have a set of view objects that serves as LOV for various other view objects. All such LOV view objects have three specific attributes, two date attributes namely EffectiveStartDate, EffectiveEndDate and a String attribute namely UserSwitch based on which the LOV list needs to be filtered.
All the view objects are having one or more view criterias with specific where clause conditions.
Apart from those view criteria conditions, invariantly, we need the following conditions also
:bindEffDate between EffectiveStartDate and EffectiveEndDate and UserSwitch = :bindUserSwitch.
We wish not to include the above condition in each and every view criteria of each and every view object (Since we have around 800 view objects and a minimum of 2 view criterias per view object). Instead, we created a dummy view object (BaseViewObject) with two bind variables :bindEffDate and :bindUserSwitch and all the LOV view objects were made to extend this BaseViewObject.
Therefore, whenever a view object atribute is attached with LOV using the above said LOV View Objects, the bind variables of the baseViewObject as well as the view object specific bind variables are available in the view accessors tab of the view object wizard where we can supply values to those bind variables.
Now, we need to construct the view criteria filter clause. To achieve this, we created a class, CustomCriteriaAdapter.java extending oracle.jbo.server.CriteriaAdapterImpl. In the getCriteriaClause() method, we included the follwoing code:
public String getCriteriaClause(ViewCriteria pViewCriteria)
ViewObject vo = pViewCriteria.getViewObject();
String userSelectSwitch = (String) vo.ensureVariableManager().getVariableValue("bindUserSwitch");
String effBgnDt = vo.getAttributeDef(vo.getAttributeIndexOf("EffectiveStartDate")).getName();
String effEndDt = vo.getAttributeDef(vo.getAttributeIndexOf("EffectiveEndDate")).getName();
String customCriteria = " ( :bindEffDate >= " + effBgnDt + " ) AND ( :bindEffDate <= " + effEndDt + " OR " + effEndDt + " IS NULL ) ";
StringBuffer completeCriteria = new StringBuffer();
String criteriaClause = super.getCriteriaClause(pViewCriteria);
if (criteriaClause != null && !criteriaClause.isEmpty())
completeCriteria.append(criteriaClause + " AND ");
completeCriteria.append(customCriteria);
if (userSelectSwitch != null && "Y".equals(userSelectSwitch))
String userSelectSw = vo.getAttributeDef(vo.getAttributeIndexOf("UserSwitch")).getName();
completeCriteria.append(" AND (" + userSelectSw + "='Y' ) ");
return completeCriteria.toString();
Issues:
The LOV list is not filtering the records based on the constructed conditions. Instead it is listing either all of the records considering only the view criteria conditions applied at design time irrespective of the userswitch and effectivedate conditions or the list is empty.
Here, my questions are,
1. Am I in the correct approach? If not, guide me in a more proper approach to achieve the same requirement.
2. If the way I am trying is correct, where things are going wrong and why the dynamic condition is not getting effected?
Kindly help in sorting out the issue.
Thanks in advance.

Hi Jobinesh,
Thanks for your response and yes, we have done exactly as what you have mentioned. As explained earlier, a baseViewObject along with its Impl class has been created and it will be extended by all the viewobjects meant for serving LOV. Therefore, the superClass for any such LOV viewObject is the baseViewObjectImpl class. In that baseViewObjectImpl(), we have over-rided the criteriaAdapter() method and returned an instance of our customCriteriaAdapter() class.
Below is the code we are using in the baseViewObjectImpl():
package model.base.vo;
import oracle.jbo.CriteriaAdapter;
import oracle.jbo.server.ViewObjectImpl;
public class BaseViewObjectImpl
extends ViewObjectImpl
* This is the default constructor (do not remove).
public BaseViewObjectImpl()
* Over-rided method of ViewObjectImpl class of the framework.
* Calls the customized criteria adapter so that the default where clauses are added to the view criteria.
* @return CriteriaAdapter.
@Override
public CriteriaAdapter getCriteriaAdapter()
return new CustomCriteriaAdapter();
I'll create a sample in HR schema and share with you shortly.
Thanks and regards.

Hi,
works for me, so the problem seems to be the way you call the method. Do you apply the VC somwhere in your code?

Search Page question - view criteria

Guys,
I am in the process of creating a search page. I need to change the search criteria on the page load. is it possible? (is this good practice to change view criteria dynamically of the search page or is it s good practice to create different search pages for each view criteria?)
Little more detail:
In entity edit page user selects the process---> based on the process i need to apply search criteria (before search page loads) --> user selects the entity and i need to show confirm message before calling stored procedure.
Thank you guys in advance...

(is this good practice to change view criteria dynamically of the search page or is it s good practice to create different search pages for each view criteria?)If you want to apply criteria values, this is OK. How do you navigate to the search page? Usually you have an initialization method that runs before the page is displayed. In the initialization method you apply the criteria values and you execute the View object query.

Apply View criteria at runtime to child View object

Hi,
I am facing issues while trying to assign View Criteria to child VO that is part of View hierarchy at runtime.
AM Model:
Parent VO ->
Child VO1
-> Child VO2
View Link between :
Parent VO -> Child VO1
Child VO1 -> Child VO2
I have to apply View criteria at runtime at Child VO1 & Child VO2, i tried setApplyViewCriteriaName from AMImpl for these VO but that doesnt work.
It works for Parent VO, So I concluded Apply VC doesnt work directly for Tree structure.
I then override executeQueryforCollection in the VO however i am never able to get the handle for the VO that is getting executed :
Here's what is happening when i fetch my VO tree from AM :
- Parent VO , Child VO are getting instantiated
- Parent VO executeQueryforCollection called
- ** After this a new instance of Child VO is getting instantiated and i dont have any control of setting the VC based on some custom property
as all get defaulted at this point.
Please suggest what can be done in this case.
PS : i can not hardcode the VC condition at View Link.
- Sam

I was able to set the VC condotinally based on property set at Parent level using following code in executeQueryForCollection :
ApplicationModule am= this.getApplicationModule();
ViewObject vo = am2.findViewObject("ParentView1");
prop = (String)vo.getProperty("Parent_prop");
if(propVo_prop.equals("Y"))
this.setApplyViewCriteriaName("VC");
super.executeQueryForCollection(object, object2, i);
is this the right way ? Any performance bottleneck ? This service can be called for 1000 Id's .
Please suggest if there is some better way.
Thanks

Outer join in view criteria: how to ?

Hello,
I have to create a VO for a LOV. I created in this VO a ViewCriteria to pass variables for the query.
The problem is that for one of this variable I have to set the clause as an outer join.
JDeveloper creates:
SELECT MyView1.Item, MyView2.Code
FROM MyView1, MyView2
WHERE MyView1.ID = MyView2.EXT_ID (+)
AND MyView1.Item = :TheItem
AND MyView2.Code = :TheCodebut I need something like:
SELECT MyView1.Item, MyView2.Code
FROM MyView1, MyView2
WHERE MyView1.ID = MyView2.EXT_ID (+)
AND MyView1.Item = :TheItem
AND :TheCode = MyView2.Code (+)

ADFboy wrote:
this is optional parameter value, in the view criteria windows is this option....
AdfBoyNo, this parameter is not optional because, in the call of the LOV it will be always set.
But the query without the outer join returns too few rows...
I tried to find where to "intercept" this programmatically, but I'm failing doing this. :(
I'll have the same problem with another field, not for a LOV but to get the value of an attribute of a VO.
Even in advanced mode the Where clause can't have parameters...

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.

Hi Rajesha,
You can follow below steps.
1)Create VOImpl for VO on which you have query based.
2)Remove Column(eg.JobId) from standard Default ViewCriteria
3)In VOImpl create method to Create View custom Criteria, Add element
public ViewCriteria addCustomVC(){
            ViewCriteria vc = null;
            vc = this.createViewCriteria();
            vc.setName("customVC");
        ViewCriteriaRow vcRow = vc.createViewCriteriaRow();
        vcRow.setConjunction(ViewCriteriaRow.VC_CONJ_AND);
        if(getJobId() != null){
            vcRow.setAttribute("JobId", "' job_id = "+getJobId()+"'");
        }else {
            vcRow.setAttribute("JobId",null);
        vc.addElement(vcRow);
return vc;
}4)Override standard method public String getCriteriaItemClause to exclude above columns
    @Override
    public String getCriteriaItemClause(ViewCriteriaItem viewCriteriaItem) {
        //JobId
        if( "JobId".equals(viewCriteriaItem.getName()) ) {
            return (String) viewCriteriaItem.getValue();
        }else{
            return super.getCriteriaItemClause(viewCriteriaItem);
    }5)Override public void executeQuery() method to add custom view criteria
@Override
    public void executeQuery()
            applyViewCriteria(addCustomVC(), true);
            super.executeQuery();
            removeApplyViewCriteriaName("customVC");
    }Thanks,

Is it even possible to dynamically apply view criteria in an ADF Web App?

This is one of those situations where something that should take an hour ends up taking days.
* I have a view.
* The view has Bind Variables associated with it.
* The view has View Criteria associated with it.
* Each of the View Criteria use different Bind Variables.
* I have a search criteria input page that receives from the user what will ultimately be used to set the bind variables.
* I have a search results page that uses the view to display a table.
* I have the code that dynamically sets view criteria and parameters. It is based on the following:
http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/bcadvvo.htm#BCGFHAGA
* This code works great, until the iterator associated with the table binding to the view is initialized. At that time, the view is reset to its defaults, and all of my code's doings are discarded. How do I know this? Because I have gone so far as to run my code that sets view criteria and binding variables dynamically in a phase event handler for the search results page in the render response phase. There is no other point at which to dynamically modify the view.
This is turning into a situation where it seems I will need 5 different views and 5 different pages in order to show a single set of query results. I cannot get dynamically applied view criteria to work in an ADF web app. Has anyone else done it? Can anyone relate to this? Are there any other suggestions before I conclude that it's not possible for this framework to handle this simple scenario?
Thanks

There must be a setting or something that I am still missing here. If I write code just like this and make sure it is executed, I still only see the results of my view executed without the view criteria applied using the default bind variable values that I supplied in the view object.
It's like the fact that I set the bind variables, the view criteria, and executed the view query programmatically is lost on the iterator -- it's like it never happened. What setting is used to ensure that the iterator uses the outcome of what I executed programmatically? There has to be a critical set or setting that I am missing.
Here is the iterator and search region definitions defined in the page def "executables" section:
<executables>
     <iterator Binds="CustomSearchView1" RangeSize="25"
              DataControl="AppModuleDataControl"
              id="CustomSearchView1Iterator"/>
    <searchRegion Binds="CustomSearchView1Iterator"
                  Customizer="oracle.jbo.uicli.binding.JUSearchBindingCustomizer"
                  id="CustomSearchView1Query"/>
    </executables>Here's the "tree" binding in the page def file:
<bindings>
   <tree IterBinding="CustomSearchView1Iterator" id="CustomSearchView1">
      <nodeDefinition DefName="Model.CustomSearchView" Name="CustomSearchView10">
        <AttrNames>
          <Item Value="CustomId"/>
          <Item Value="CustomProjectNumber"/>
          <Item Value="CustomName"/>
          <Item Value="CustomStatus"/>
          <Item Value="CustomStatusDate"/>
        </AttrNames>
      </nodeDefinition>
    </tree>
</bindings>In an effort to take page flow out of this mess, I had modified this to include the search criteria and search results on a single page. So, I now have a "Search" button. When the "Search" button is clicked, the action method does the following:
    public String searchActionListener ()
          // Get search criteria from select one choice and text input controls.
          AppModule appModule =
                ( AppModule ) Configuration.createRootApplicationModule (
                    "Model.AppModule",
                    "AppModuleLocal");
          appModule.customSearch( searchCriteria1,
                                               searchCriteria2,
                                               searchCriteria3 );
    }In my application module this translates to:
    public void customNoticeSearch ( String searchCriteria1, String searchCriteria2, String searchCriteria3)
       CustomSearchViewImpl searchViewImp =
           ( CustomSearchViewImpl ) this.getCustomSearchView1 ();
       searchViewImp.customExecuteQuery ( searchCriteria1, searchCriteria2, searchCriteria3);
    }Finally, in my custom view object implementation code:
    public void customExecuteQuery ( String searchCriteria1, String searchCriteria2, String searchCriteria3 )
        // Set-up the parameters that are part of the core query.
        this.setp_searchCriteria1( searchCriteria1);
        this.setp_searchCriteria2( searchCriteria2);
        if ( searchCriteria3 != null )
            ViewCriteriaManager vcm = this.getViewCriteriaManager();
            ViewCriteria vc = vcm.getViewCriteria ( "WithLastCriteria" );
            this.setp_searchCriteria3( new Number ( searchCriteria3 ) );
            this.applyViewCriteria( vc );
        System.out.println ("This is fun.");
        this.executeQuery();
    }This code executes, but the results table is empty, and I know that there are results, because I can execute use execute with params to execute the base query and get the correct results back.
Thanks for taking a look at this.

How to change the view criteria at run time for af:query

Hi,
I've a usecase where I need to change the view criteria of the af:query at run time.
Use case:
=======
1) Consider a check box (Show Emps Under Dept 10) in the query panel when user selects and clicks 'Search' button should show the employees under dept 10. If user searches without selecting the check box, the results should show all the employees in all the departments.
2) I need to have a check box always in the query panel. Its mandatory.
The way I implemented:
==============
1) Created a transient variable 'Show Emps Under Dept 10' in the EmployeeVO and also created a bind variable bind_DeptNo.
2) Create a view criteria 'AllEmployees' which has only the transient attribute as the view criteria item and whose value set to 'false' by default.
3) Created another view criteria 'EmpUnderDept' which has 'DepartmentId' as the view criteria item and whose value set to the bind variable 'bind_DeptNo'.
4) Dropped the view criteria 'EmpUnderDept' as the 'af:query' panel in the jspx page.
5) Overridden the queryListener as '#{EmpBean.empSearch}'
6) Has the below code in the empSearch method as below. When user selects the check box, applying the other criteria 'EmpUnderDept' and setting the bind variable to '10'.
public void empSearch(QueryEvent queryEvent) {
// Add event code here...
QueryDescriptor queryDesc = (QueryDescriptor) queryEvent.getDescriptor();
ConjunctionCriterion conCrit = queryDesc.getConjunctionCriterion();
List<Criterion> criterionList = conCrit.getCriterionList();
List criterionValues = new ArrayList();
Object criteriaValue = null;
int criteriaNo = 0;
DCBindingContainer bc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
FacesContext facesContext = FacesContext.getCurrentInstance();
for (Criterion criterion : criterionList) {
AttributeDescriptor attrDescriptor = ((AttributeCriterion)criterion).getAttribute();
System.out.println("============== attrDescriptor.getName() =================== " + attrDescriptor.getName());
criteriaValue = ((AttributeCriterion)criterion).getValues().get(0);
if(criteriaNo==0) {
Boolean val = (Boolean) ((AttributeCriterion)criterion).getValues().get(0);
if (val.equals(true)) {
OperationBinding method = (OperationBinding) ADFUtil.findOperation("ExecuteWithParams");
if(method!=null) {
Map params = method.getParamsMap();
//params.put(key, value)
method.getParamsMap().put("bind_DeptId", 10L);
method.execute();
ADFUtil.invokeMethodExpression( "#{bindings.EmpUnderDeptCriteiaQuery.processQuery}", queryEvent);
} else {
//ADFUtil.invokeEL("#{bindings.ExecuteWithParams.execute}");
ADFUtil.invokeMethodExpression( "#{bindings.AllEmployeesCriteriaQuery.processQuery}", queryEvent);
But this approach is not working and its always showing all the employees in all the departments.
Please let me know if there is a way to change the view criteria at run time depending on the values set at run time for one of the view criteria items.
JDev version am using is '11.1.1.5'
Thanks,
Lakshman

Hi Shay,
It worked for me without overriding the executeQuery() method in the ViewImpl.java.
Instead of creating 2 view criteria, I created only one which has both transient variable and the DepartmentId = <bind_DeptId>. With the above code, it worked properly. Now I am using only one view criteria.
Thank you.

How to populate View Criteria Item programatically

Hi,
I'm using Jdeveloper 11.1.2.3.0.
I created a query panel with operator Between for EmployeeId attribute and used bind variables in the VC fromEmpId, toEmpId, and dropped the VC as a query panel on a jsf page.
At run time, when i entered a value in the from field and tabout, to field should be populated with from field value. Can anybody let me know how to achieve this?
I could set to value on click of search using below code in the bean, search is performed without any issue. Only thing is i want to see the value in the To Field.
ensureVariableManager().setVariableValue("toEmpId"l, value from the From field);
Thanks,
Vinod

Hi,
Refer to blog https://forums.oracle.com/thread/2538913
You can follow below steps.
1)Create VOImpl for VO on which you have query based.
2)Remove Column(eg.JobId) from standard Default ViewCriteria
3)In VOImpl create method to Create View custom Criteria, Add element
public ViewCriteria addCustomVC(){
ViewCriteria vc = null;
vc = this.createViewCriteria();
vc.setName("customVC");
ViewCriteriaRow vcRow = vc.createViewCriteriaRow();
vcRow.setConjunction(ViewCriteriaRow.VC_CONJ_AND);
if(getJobId() != null){
vcRow.setAttribute("JobId", "' job_id = "+getJobId()+"'");
else {
vcRow.setAttribute("JobId",null);
vc.addElement(vcRow);
return vc;
4)Override standard method public String getCriteriaItemClause to exclude above columns
    @Override     public String getCriteriaItemClause(ViewCriteriaItem viewCriteriaItem) {
//JobId
if( "JobId".equals(viewCriteriaItem.getName()) ) {
             return (String) viewCriteriaItem.getValue();
else

View Criteria in ADF Query Panel with Table-Class Cast Exception

Hi,
I am getting Class Cast Exception when using view criteria for ADF Query Panel with Table. The version I am using is 11g Release 1(11.1.1.2.0)
Here is what I did:
1. created a view criteria on a view object
2. all are optional
3. all are Strings
3. Dragged the view criteria as a query component (ADF Query panel with Query table) on to the design layout
and the error when I clicked the Search button is:

Hi Frank.
I'm using JDev 11.1.1.3.0 as you suggest the error is no longer present in the latest version.
I can pick my query from the "Saved Search" pick list on the QueryPanel list of queries just fine, and it sets up the filter properly, but when I press the "Search" button, I get the same reported error...
