Set view criteria on af:query choice LOV field
i have an af:query. one of the fields is a choice. the LOV for the choice come from a VO. i need to set view criteria for the query for the LOV for the choice. that is, the query for the values of the choice requires view criteria.
moreover, that search criteria is only known by the view. because the hooks for the choice are set up entirely in the model, i don't see how it would ever be possible to use values from the view to define the query for the LOV for the choice.
any ideas?
Assuming that you can have a method at the AM level that sets the viewCriteria for your VO, you can drag this method to the page flow to be executed before you go into the query page - this will set the right condition for the list that needs to populate the LOV.
Then the query component can use that VO as an LOV like this:

Programmtically Setting View Criteria in ADF Query Component
I have created two view criterias for a View Object and used ADF Query component for searching. User can select any one of the View Criteria from "saved search" in ADF Query component. but i want to set it programmatically based on some business rules. How i can do that?
No I don't want to set view criteria on search click. Actually I have ADF Query component on my page which is by default disabled. There are also some fields outside the query component on the value of which i enable ADF Query component and wants to set a particular ViewCriteria based on context. All ViewCriterias are defined and listed in "saved search" of ADF Query component but i don't want to allow user to select it but wants to application set it automatically based on context. For it i will be needed to set a particualar ViewCriteria for ADF Query component through code and then refresh ADF Query component to show newly set ViewCriteria. I know how to refresh query component or any other component through code but don't know how to set ViewCriteria on ADF Query component?

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:

VenkateshHi 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...

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

Auto suggest behavior for af:query component LOV fields.
Hi,
I am new to ADF development and need help on implementing auto suggest behavior to the LOV fields generated by af:query component. For inputList and inputCombo.. fields we can add af:autosuggestbehavior tag to enable this. How do we enable the same for af:query generated LOV fields.
Regards,
C.RThanks Timo for such a quick response.
JDev version we are using is 11.1.1.6.0
Unfortunately, we have gone too far with the AF:Query and Everything else is working apart from Auto-Suggest on AF:Query. Now will take a lot of time to implement and test. Also, users will have to spend considerable time to test it again.
Thanks and Regards,

Applying different view criterias to af:query based different situations
Hi all;
Lets say i have 3 different view criterias ....and i want to apply only one of them to af:query based user's role....
I dont have an idea how to do that...My only clue is my supervisor mentioned to me i can use page definition to do that;
<searchRegion Criteria="DepartmentViewCriteria" Customizer="oracle.jbo.uicli.binding.JUSearchBindingCustomizer"
Binds="DepartmentView1Iterator" id="DepartmentViewCriteriaQuery"/>Can u help me on this matter please!
If post is too shallow to understand i can elaborate more...

Oracle DB 11gCreate a custom public method in yr applicationmoduleImpl class. Get the viewcriteria of target vo or programmatically create yr viewcriteria.
Based on current loggedInUser role which can be access by ADFContext.getCurrent().getSecurityContext().getUserRoles(), u can apply specific viewcriteria on VO.
After that u can follow this link - http://dstas.blogspot.com/2010/09/adf-11g-methodaction-and-invokeaction.html, from +"We will now expose the method in the client interface of the AM"+ teopic.
At the end u will be able to execute this method from pagedef file, whenever u enter to this page.
Hope this helps. -
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?
ThanksThere 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. -
Tabular form (select list Query based LOV)
Hi all,
I have this situation:
a tabular form with two "select list (query based LOV)" fields.
The first one must affect elements in the second one. And so the second query based LOV field should has a "where attr1 = first_list_selected_value" in the query.
Is this possible ? Could you show me some advices ?
thanks in advance.OK, thank you.
But maybe I wasn't too clear.
I need cascading LOV for each row of my tabular form.
I have a EMP tabular form
select
"ROWID",
"EMPNO",
"ENAME",
"JOB",
"MGR",
"HIREDATE",
"SAL",
"COMM",
"DEPTNO"
from "#OWNER#"."EMP" I need a Select List for DEPTNO for each record of table. After set a value, the second "Select List" for ENAME should be affected automatically. -
LOV view criteria missing in af:query field when AM pooling is disabled
Hi all,
Again, another strange behaviour with fields in af:query when AM pooling is disabled.
I have a field with a LOV in the af:query area. This LOV has a view criteria that involves a bind variable. In the VO, the view accessor for this LOV applies the view criteria and sets the bind variable. When AM pooling is disabled, double clicking a row or clicking the OK button in the LOV window removes the where clause defined by the view criteria. When activation occurs, the bind variable still exists but the framework doesn't know where to apply it...
Any help will be very appreciated,
Thanks
JDeveloper 11.1.1.3.0 with ADF BC
We've just realised that this behaviour occurs even when pooling is enabled. So this is becoming now a serious problem.
The scenario is as following: We have two LOVs in the search area (af:query). One of them is dependent on the other. Then, this second LOV has a view criteria and a bind variable representing the value selected for the first LOV. The query for the second LOV is filtered properly, but once a value has been selected and the LOV window dismissed, nothing is returned to the field.
We have observed that SecondLovViewImpl.executeQueryForCollection() method executes twice:
1. When LOV is opened: here, the bind variable is correctly setted.
2. When a row in the LOV table is selected: here, the bind variable is reset to null.
The log says (in Spanish):
<OracleSQLBuilderImpl><bindParamValue> [46062] Binding null of type 12 for "bindProgram"
<FacesCtrlLOVBinding$ListOfValuesModelImpl><_getRowFromSelectedRowKey> ADFv: No se ha encontrado ninguna fila para rowKey: [oracle.jbo.Key[P1 SP11 ]].
I would be very grateful if somebody asked me... even for saying "this is nonsense", "this is a known bug", "cascading LOVs are not supported by af:query", or anything else... If a code snippet is required, I'll put it as well.
Thanks in advance
Edited by: Marge on 02-sep-2010 5:41Hi,
there are two bugs associated with bind variables in successors that I am aware of. One of them is supposed to be fixed in the next patch set, another one is still open. However, both problems were found with AM pooling enabled as well, so I don't know this is the same problem (though it sounds like). If you can, I suggest to create a reproducible testcase on one of the Oracle database schema, like HR or OE, and file a bug. If you don't have a time for or access to support, send the test case in a zip file (rename ".zip" to ".unzip") to the mail Id you find in my OTN profile. However, be aware that when I file the bug then it wont be visible for you, nor can it be escalated on your behalf. Anyway, at least it would get filed

How to set the default value of a LOV that is found in a view criteria
HI,
I need to set the default value of an LOV that is found in a view criteria. I tried to set a groovy expression but unfortunately it wasn't read. i also tried to bind the LOV to a bind variable and set the value of the bind variable in the constructor of my backing bean but unfortunately the default value appeared the second time i entered the screen and not on page load.
Can anyone advise where can i set the default value,
Thanksif you want some default value in LOV. you go to edit list of value wizard-> UI hint->include no selection Item checkbox -checked.use labeled item first of list- and beside that put the label. but when you try to get value, it will show null.but you can manipulate in ur java , if it default value

How to apply common View criteria for all LOV View programatically?
Hi,
In my application I use nearly 100 VOs, which will be mapped as LOV to some base VOs. These VOs are not only for LOV but also will be used directly in screen as read-only table. All these VOs contains EFF_BGN_DTand EFF_END_DT. Requirement is to display only the active records in VO.
We don't want to crete view criteria at design time for each and every VO. Instead we want to have a base ViewObjectImpl class, create at runtime and add this common criteria with the existing view criterias (If any given, which are actually required for the developer for screen specific functionality).
NOTE: As all of our VOs are custom java data source implemented and none of them have queries, we cannot use whereclause API but only ViewCriteria.
We want to create a view criteria, that somewhat looks like the below condition.
( (TO_CHAR( EffBgnDt, 'yyyy-mm-dd') <= '2010-02-01' )
AND (TO_CHAR( EffEndDt, 'yyyy-mm-dd') >= '2010-02-01' )
OR
( (TO_CHAR( EffBgnDt, 'yyyy-mm-dd') <= '2010-02-01' )
AND (EffEndDt IS NULL )
)Question:
1. Which is the best place in ViewObject class, where I will be able to create common view criteria, include it with existing criterias.
Thanks in Advance.
RaghuNo it is not working. I've tested. When i test your implementation in my sample using AM tester, it is not at all going inside getCriteriaItemClause(ViewCriteriaItem pViewCriteriaItem). For example when i say, AM.findViewObject(String ViewObjectName), followed by getEstimatedRowCount(), it should apply common filter criteria and give me the result.
Given below required scenario:
Department table:
ID DEPT_NAME START_DATE END_DATE
1 Hr 1-Jan-2010
2 Purchasing 1-Jan-2010 31-Dec-2010
3 Shipping 1-Jan-2010 31-Dec-2055
4 Sales 1-Jan-2010
Common criteria to be applied (Programatically) : :bind_current_date between StartDate and EndDate or :bind_current_date >= StartDate and EndDate is null
VO specific view criteria (may vary VO to VO): DeptName not equal to 'Sales'
Expected Result:
Case 1:
a. DeptView = AM.findViewObject("DepartmentVO")
b. DeptView.getEstimatedRowCount()
It should give me 3 records (Hr, Shipping, Sales)
Case 2:
a. DeptView = AM.findViewObject("DepartmentVO")
b. Create View Criteria 'NotSalesDeptVC', which should not list out Sales department.
c. Apply NotSalesDeptVC using RowSet rowSet = (RowSet) this.findByViewCriteria(NotSalesDeptVC, -1, ViewObject.QUERY_MODE_SCAN_VIEW_ROWS)
d. rowSet.getEstimatedRowCount()
It is in-memory filtering, will not disturb the default rowset, should give me 2 records (Hr, Shipping)
Case 3:
a. DeptView = AM.findViewObject("DepartmentVO")
b. Apply 'NotSalesDeptVC' to the default row set, followed by executeQuery
c. DeptView.getEstimatedRowCount()
It should give me 2 records. (Hr, Shipping)
Case 4:
a. DeptView = AM.findViewObject("DepartmentVO")
b. Unapply the applied 'NotSalesDeptVC', followed by executeQuery
c. DeptView.getEstimatedRowcount()
It should give me 3 records (Hr, Shipping, Sales)Essence is at any point of time, User should always work with active records. He no need to write extra logic to retrieve only the active records but the base Viewobject impl should have. Note, All of my view objects are custom java data source implemented and not query based. Similarly it does not meant that all of my VOs will be having some business specific View criteria. Some VOs may have. Some VOs may not have. However basic active records criteria is applicable for all VOs -
Applying distinct to a query search panel view criteria
I have a VO that returns multiple instances of the same project code...In the ADF query panel I only need to display a distinct set of these project codes...
When building a simple ADF query panel based on a view criteria declaratively the project codes will repeat themselves in the select one choice component of the query panel.
What is the best way to apply a distinct to a view criteria of this sort?

In one case the tree table is 3 levels deep, in the other case it's only 2 with different data being at the root node.
What I've done so far:
1) I exposed the data relationship for these two ways of viewing the data in the application module's data model.
2) I created a view criteria in the two view objects that are at the root of the relationships, where (for simplicity sake) I'm only comparing a single field.
This is in one view object:
<ViewCriteria
Name="PartsVOCriteria"
ViewObjectName="gov.nasa.jpl.ocio.qars.model.views.PartsVO"
Conjunction="AND">
<Properties>... </Properties>
<ViewCriteriaRow
Name="vcrow23"
UpperColumns="1">
<ViewCriteriaItem
Name="PartDiscrepantItemsWithIRVO"
ViewAttribute="PartDiscrepantItemsWithIRVO"
Operator="EXISTS"
Conjunction="AND"
IsNestedCriteria="true"
Required="Optional">
<ViewCriteria
Name="PartDiscrepantItemsWithIRVONestedCriteria"
ViewObjectName="gov.nasa.jpl.ocio.qars.model.views.PartDiscrepantItemsWithIRVO"
Conjunction="AND">
<ViewCriteriaRow
Name="vcrow26"
UpperColumns="1">
<ViewCriteriaItem
Name="InspectionRecordNumber"
ViewAttribute="InspectionRecordNumber"
Operator="="
Conjunction="AND"
Value=""
Required="Optional"/>
</ViewCriteriaRow>
</ViewCriteria>
</ViewCriteriaItem>
</ViewCriteriaRow>
</ViewCriteria>
and this is in the other view object:
<ViewCriteria
Name="IRSearchCriteria"
ViewObjectName="gov.nasa.jpl.ocio.qars.model.views.InspectionRecordVO"
Conjunction="AND">
<Properties>... </Properties>
<ViewCriteriaRow
Name="vcrow7"
UpperColumns="1">
<ViewCriteriaItem
Name="InspectionRecordNumber"
ViewAttribute="InspectionRecordNumber"
Operator="="
Conjunction="AND"
Required="Optional"/>
</ViewCriteriaRow>
</ViewCriteria>
3) I had a query panel and tree table auto-generated by dragging the data control for ONE of the view object data relationship that's exposed in the app module. Then I created a second query panel and tree table the same way but using the data control for the other. I'm hiding one of the query panels permanently and toggling the visibility of the tree tables based on the display mode the user chooses. Both tables have separate bindings and iterators.
This is a portion of the page definition:
<executables>
<variableIterator id="variables"/>
<searchRegion Criteria="IRSearchCriteria"
Customizer="oracle.jbo.uicli.binding.JUSearchBindingCustomizer"
Binds="InspectionRecordVOIterator"
id="IRSearchCriteriaQuery"/>
<iterator Binds="InspectionRecordVO" RangeSize="25"
DataControl="QARS_AppModuleDataControl"
id="InspectionRecordVOIterator" ChangeEventPolicy="ppr"/>
<iterator Binds="Root.QARS_AppModule.PartsVO1"
DataControl="QarsMasterAppModuleDataControl" RangeSize="25"
id="PartsVO1Iterator"/>
<searchRegion Criteria="PartsVOCriteria"
Customizer="oracle.jbo.uicli.binding.JUSearchBindingCustomizer"
Binds="PartsVO1Iterator" id="PartsVOCriteriaQuery"/>
</executables>
4) I've created a custom queryListener to delegate the query event.
This is in my advanced search jsp page:
<af:query id="qryId1" headerText="Search" disclosed="true"
value="#{bindings.IRSearchCriteriaQuery.queryDescriptor}"
model="#{bindings.IRSearchCriteriaQuery.queryModel}"
queryListener="#{pageFlowScope.SearchBean.doSearch}"
queryOperationListener="#{bindings.IRSearchCriteriaQuery.processQueryOperation}"
resultComponentId="::resId2" maxColumns="1"
displayMode="compact" type="stretch"/>
This is in my backing bean:
public void doSearch(QueryEvent queryEvent) {
String bindingName = flag
? "#{bindings.IRSearchCriteriaQuery.processQuery}"
: "#{bindings.PartsVOCriteriaQuery.processQuery}";
invokeMethodExpression(bindingName, queryEvent);
private void invokeMethodExpression(String expr, QueryEvent queryEvent) {
FacesContext fctx = FacesContext.getCurrentInstance();
ELContext elContext = fctx.getELContext();
ExpressionFactory eFactory = fctx.getApplication().getExpressionFactory();
MethodExpression mexpr =
eFactory.createMethodExpression(elContext, expr, Object.class, new Class[] { QueryEvent.class });
mexpr.invoke(elContext, new Object[] { queryEvent });
When no inspection record number (the only search field so far) is supplied in the query panel, then it behaves correctly. Namely, the tree tables shows all search results. However, when an inspection record number is supplied the tree table that was created with the query panel in use (remember there are two query panels, one of them is hidden) shows a single result (this is correct) while the other tree table (the one with the hidden query panel that isn't in use) shows all results (this is NOT correct).
Is what I'm trying to accomplish even doable? If so, what am I missing?
I'm using JDeveloper 11.1.1.7
Thanks,
BillI ended up keeping one query panel permanently visible and the other permanently hidden. When performing a search using the table that has the hidden query panel, I seed the query descriptor for the hidden query panel using the visible query panel's query descriptor and then delegate the request:
public void doSearch(QueryEvent queryEvent) {
String bindingName = null;
if(isIrTableRendered()) {
bindingName = "#{bindings.IRSearchCriteriaQuery.processQuery}";
} else {
seedPartsQueryDescriptor();
bindingName = "#{bindings.PartsVOCriteriaQuery.processQuery}";
queryEvent = new QueryEvent(partsQuery, partsQuery.getValue());
invokeMethodExpression(bindingName, queryEvent);
private void seedPartsQueryDescriptor() {
ConjunctionCriterion criterion = irQuery.getValue().getConjunctionCriterion();
for(Criterion criteria : criterion.getCriterionList()) {
AttributeCriterion attributeCriteria = (AttributeCriterion)criteria;
List values = attributeCriteria.getValues();
String qualifiedName = attributeCriteria.getAttribute().getName();
int indexOfDot = qualifiedName.lastIndexOf(".");
String name = indexOfDot < 0
? qualifiedName
: qualifiedName.substring(indexOfDot + 1);
ConjunctionCriterion partsCriterion =
partsQuery.getValue().getConjunctionCriterion();
for (Criterion partsCriteria : partsCriterion.getCriterionList()) {
AttributeCriterion partsAttributeCriteria =
(AttributeCriterion) partsCriteria;
String partsQualifiedName =
partsAttributeCriteria.getAttribute().getName();
if (partsQualifiedName.endsWith(name)) {
partsAttributeCriteria.setOperator(attributeCriteria.getOperator());
List partsValues = partsAttributeCriteria.getValues();
partsValues.clear();
for (int i = 0, count = values.size(); i < count; i++) {
partsValues.set(i, values.get(i));
private void invokeMethodExpression(String expr, QueryEvent queryEvent) {
FacesContext facesContext = FacesContext.getCurrentInstance();
ELContext elContext = facesContext.getELContext();
ExpressionFactory expressionFactory =
facesContext.getApplication().getExpressionFactory();
MethodExpression methodExpression =
expressionFactory.createMethodExpression(elContext, expr, Object.class, new Class[] { QueryEvent.class });
methodExpression.invoke(elContext, new Object[] { queryEvent });
Then when the advanced/basic button is pressed for the visible query panel, I programmatically set the same mode for the hidden query panel:
public void handleQueryModeChange(QueryOperationEvent queryOperationEvent) {
if(queryOperationEvent.getOperation() == QueryOperationEvent.Operation.MODE_CHANGE) {
QueryMode queryMode = (QueryMode) irQuery.getValue().getUIHints().get(QueryDescriptor.UIHINT_MODE);
QueryDescriptor queryDescriptor = partsQuery.getValue();
queryDescriptor.changeMode(queryMode);
AdfFacesContext.getCurrentInstance().addPartialTarget(partsQuery); -
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,
LakshmanHi 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. -
Using IN keyword in an sql query in a view criteria
Hi,
I am using jdev 11.1.1.1.0 and defined an lov query/viewobject as
select a, b, c from myTable
I now need to predefine filtering for lov search functionality and need something like the following
select a, B, c from myTable where B in ('X','Y')
I could not find a way to do it (i.e. specify the use of IN Keyword) in the Create View Criteria dialog box. I tried to define OR, but is that the best way to redefine IN as i have a long list (the above is just an example)
(( ( (UPPER(B_FLAG) = UPPER('X') ) ) OR ( (UPPER(DISPLAY_FLAG) = UPPER('Y') ) ) ))If you know how many variables are in your "in" You can just write this in the sql query of your VO:
