Bind variable set error

I get the exception when using bind variables in the VO (sql-based).
VO is based on the SQL query from the pipelined table function, for instance: select * from table(some_function(:bind1, :bind2)). This query returns a table, which I want to display on the separate page.
So, from fragmented bounded task flow make a call for the new taskflow (non-fragmented, bounded) in the dialog window. Specify the input parameters for the called taskflow. These parameters I get in called taskflow, it is ok. The very first activity in the called taskflow is the ExecuteWithParams method. I bind input parameters from the pageFlowScope to the ExecuteWithParams parameters, but IN PL/SQL FUNCTION (and ADF log) I SEE, THAT THESE PARAMETERS IS NULL, BUT ONLY FOR THE FIRST TIME THE EXECUTEWITHPARAMS IS CALLED.
StackTrace is tje following:
[2555] ViewObject: <MyVO> close single-use prepared statements
[2556] QueryCollection.executeQuery failed...

Hi,
Just made a simple use case at the model level and when I test the AM, it works. So problem is in view - task flows part. can you provide more info to reproduce also this task-flows part?
regards,
Branislav

Bind variable setting for standalone stackLayout VO region

How do I define the bind variable for this scenario? Eventually, I plan on adding this as a personalization to the requisition notification, so I figured I need the bind variable so I can link the region to the header (or is this not even the correct approach???).
I have a query with a bind variable defined (:1, which is the requisition_header_id) on a standaalone stackLayout region, and I tried defining the variable as an optional URL parameter (&1=14247), but when I run my test I continue to get the following:

Srini -
I did the following:
public void initQuery(String reqHeaderId)
if ((reqHeaderId!= null) && (!("".equals(reqHeaderId.trim()))))
addWhereClause("prl.requisition_header_id = :1");
setWhereClauseParams(null);
setWhereClauseParam(0,reqHeaderId);
executeQuery();
else
executeQuery();
I made it an addWhereClause because there's already a where clause in the VO query, wo I assumed this would just append to the rest of the where clause already there. My URL has $reqHeaderId=14247; however, now it looks like all distribution lines are being returned rather than just the one I expect in this example. So, is there something else I need to be doing?

Sqlplus exit with bind variable gives error

Hi,
I want to return the ID-value from an insert-statement back to the OS, but I can't catch it properly in a variable to exit that variabel. here's the script:
variable logid NUMBER;
select id_seq.nextval into :logid from dual;
-- insert into Tab_A .....
---values :logid..... -> nothing to do with the problem
exit :logid;
I get this:
SP2-0670: Internal number conversion failed
To make a minimum test, I do:
variable logid NUMBER;
select 5 into :logid from dual;
exit :logid;
but I still get that error !
what am I doing worng here ?
it is a number isn't it ?
why do i get a conversion-error than ?
how do I fill and return a variable correctly ?
thanks for any help, Lao De

Your problem is with your select statement. SELECT...INTO is PL/SQL, not SQL, and can not be used to set a variable. Alternatives:

HELP: VO Bind variable gets lost, VO passivation checked!

JDEv 10.1.3.0.4 + Struts/ADF
I have a VO with one bind variable "accountId", this VO is the "root master" of the hierarchy => not a detail of a link.
I added a method in the VO (that is part of one AM only) to set the bind variable:
WHERE CLAUSE:
(Wevent.EVENT_ID = WeventDesign.EVENT_ID) AND (Wevent.ACCOUNT_ID = AccountOwner.ACCOUNT_ID) AND (Wevent.PHOTOGRAPHER_ACCOUNT_ID = AccountPhotoGrapher.ACCOUNT_ID) AND (Wevent.EVENT_STATUS BETWEEN 30 AND 80) AND (Wevent.ACCOUNT_ID = :0)
Binding Style: Oracle Positional
private Number accountId = null;
private Object[] DEFAULT_VALUES = new Object[]{ Constants.NUMBER_ZERO };
private static int NUM_DEFAULT_VALUES = DEFAULT_VALUES.length;
public Row setAccountId(Number newAccountId)
    Row row = null;
    if (newAccountId == null)
    this.accountId = null;
    this.clearCache();
    System.out.println(getClass().getName()+".setAccountId no exeqry newAccountId == null");
    else
      this.accountId = newAccountId;
      row = this.getCurrentRow();
      if(row == null || row.getAttribute("AccountId") == null || !newAccountId.equals(row.getAttribute("AccountId")))
// not good account events !!!!
      this.setWhereClauseParam(0,newAccountId);
      System.out.println(getClass().getName()+".setAccountId before exeqry newAccountId: "+newAccountId);
      this.executeQuery();
//      System.out.println(getClass().getName()+".setAccountId after exeqry getRowCount(): "+this.getRowCount());
      row = this.first();
        if (row != null)
        System.out.println(getClass().getName()+".setAccountId after exeqry+first row.getAttribute(AccountId): "+row.getAttribute("AccountId"));
        else
        System.out.println(getClass().getName()+".setAccountId after exeqry+first row is null => no rows");
      else
      System.out.println(getClass().getName()+".setAccountId NO exeqry this.accountId: "+this.accountId+", newAccountId: "+newAccountId+" current is null? "+(this.getCurrentRow() == null));
      this.accountId = newAccountId;
      DEFAULT_VALUES[0] = newAccountId;
      System.out.println(getClass().getName()+".setAccountId this.accountId: "+this.accountId+", newAccountId: "+newAccountId+", DEFAULT_VALUES[0]: "+DEFAULT_VALUES[0]);
    return row;
In the AMImpl class I added a service method:
public Row prepareModelForEventAccountOwnerList(Number accountId)
    EventAccountOwnerListExtVOImpl eventAccountOwnerListExtVOImpl = this.getEventAccountOwnerListExtVO1();
    return eventAccountOwnerListExtVOImpl.setAccountId(accountId);
}When the user logs in his accountId is retrieved and stored in the HttpSession.
and the service method is called.
Ok at this point.
I have a Page that displays the view.
In the class AccountEventsAction that extends PagingDataForwardAction I have following initializeModelForPage method.
protected void initializeModelForPage(DataActionContext ctx)
    System.out.println(getClass().getName()+".initializeModelForPage BEGIN "+System.currentTimeMillis());
    WebAccountAM webAccountAM = (WebAccountAM) this.getApplicationModule(WebConstants.AM_WEBACCOUNT,ctx);
    if (webAccountAM == null)
     // return error
     System.out.println(getClass().getName()+".initializeModelForPage webAccountAM not found.");
    else
      UserContainer userContainer = this.getUserContainer(ctx);
      Row row = webAccountAM.prepareModelForEventAccountOwnerList(userContainer.getAccountId());
      if (row != null)
      System.out.println(getClass().getName()+".initializeModelForPage userContainer.getAccountId(): "+userContainer.getAccountId()+", EventId: "+row.getAttribute("EventId")+", current row key: "+row.getKey());
      else
      System.out.println(getClass().getName()+".initializeModelForPage userContainer.getAccountId(): "+userContainer.getAccountId()+", First row is null? "+(row == null));
      super.initializeModelForPage(ctx);
    }To my knowledge because this page is accessible only after login and the VO passivation state (+bind vars ..) is yes it shouldn't be necessary?
FIRST PROBLEM:(non blocking)
=============
I noticed in my trace that the VO current row is null when the service method gets called in the initializeModelForPage binding method?
So the query gets re-exceuted, is this normal??
SECOND PROBLEM (blocking)
================
At some point the Web app. the frameworks calls the executeQueryForCollection and an exception is thrown as if the bind variable was lost???
extract:

Your help is required and will be appreciated
Fred

More info:
I added a trace in the executeQueryForCollection method of the VO.
As I said before the binding var is set on login and in initializeModelForPage
but when the executeQueryForCollection is called by framework later on in the action cycle, it is called without any parameters => bind variables = numUserParams: 0 ??
trace extract
com.photoswing.model.site.EventAccountOwnerListExtVOImpl.executeQueryForCollection this.accountId: null, numUserParams: 0, DEFAULT_VALUES[0]: 0
I suppose that some code must be added so that my bind variables will be part of the passivation process.
Can you help me with that?
Thanks for your time.
Fred
PS It's my second day on this problem.

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:

Af:query with bind variables and Saved Search

I have a VO and view criteria(VC).
VC has a criteria item ObsoleteDate with range specified as bindVariables "dateFrm" and "dateTo" I dragged & dropped the named criteria as af:Query with table. Table toolbar has 2 buttons in which I set & clear the bind variables. Data is fetched as per as expected based on the VC & bind variables.
The problem is,
If I save my search with bind variables set and swap between the saved searches , all works fine. But the moment I clear bind variables & swap between searches.. "dateFrm" is populated and "dateTo" is null and I get an Exception oracle.jbo.AttrValException: JBO-27035: Attribute Obsolete Date: is required.
Why is this happening?? Saved search is supposed to save the VC with all the bind values set while saving and clearing bind variables shouldn't affect the saved search, right?? Or I have understood it wrong?
I am using JDeveloper 11.1.2.3.0
Thanks

Getting error 025036 while setting bind variable value

Hi,
I have created a view object (ViewObj) having bind variable (Bind_Val).
I am writing custom java method in AppModuleImpl.java, so that I can use that in serviceInterface.
my method is:
public void Met(String a){
ViewObjImpl vo=new ViewObjImpl();
vo.setBind_Val(a);
I tried the below method also:
public void Met(String a){
ViewObjectImpl vo=new ViewObjectImpl();
vo.setNamedWhereClauseParam("Bind_Val",a)
But when I am running the AppModuleServiceImpl.java and select the Met method and pass the value for a. It is giving me error 02036.
How to set the bind variable value in AppModuleImpl.java??
Thanks,
Rohit

Hi Frank,
Thanks for reply. It was helpful.
Please go through the below mentioned two queries.
My sql query is:
SELECT Message.MESSAGE_ID,
MessageProp.VALUE,
MessageProp.MSG_PROP_ID
FROM MESSAGE Message, MESSAGE_PROP MessageProp
WHERE (MessageProp.Key='From' OR MessageProp.Key='To')AND Message.MESSAGE_ID = MessageProp.MESSAGE_ID And MessageProp.Value='B'
and I have created one view criteria where I am giving the condition as MessageId=:Bind_MessageId.
And then I am executing my findViewCriteria method from AppModuleServiceImpl where I am passing the value for Bind_MessageId and I am getting the output as I want.
Now I am modifying my query as:
SELECT Message.MESSAGE_ID,
MessageProp.VALUE,
MessageProp.MSG_PROP_ID
FROM MESSAGE Message, MESSAGE_PROP MessageProp
WHERE (MessageProp.Key='From' OR MessageProp.Key='To')AND Message.MESSAGE_ID = MessageProp.MESSAGE_ID And MessageProp.Value=:Bind_Value
and setting the value for :Bind_Value programatically as:
public void test(String s){
ViewObjectImpl view = this.getViewObj1();
VariableValueManager vm = view.ensureVariableManager();
vm.setVariableValue("Bind_Value",s);
**Note- I have written this custom method in AppModuleImpl.java class
Then firstly I am executing test method from AppModuleServiceImpl to set the value for :Bind_Value. After that I am executing findViewCriteria method but then I am not getting any record.
**Note-I am not getting any error.
I want to set Bind_Value programatically and then I want to execute my FindViewCriteria from serviceInterface.
Thanks,
Rohit

Error when Setting value to Bind variable in View Link used in HGrid

Hi
I have requirement to pass profile id as bind variable, I have created a VO based on below Query.
select 'N' Is_Selected, 'N' Is_Already_Selected, 'N' Is_Selected_Copy, a.*
from XXPA_STATE_CONST_DTLS_V a, xxpa_state_const_dtls b
where a.child_id = b.child_id(+)
and b.profile_id(+) = :1
View Link Query that is being generated is
SELECT * FROM (select 'N' Is_Selected, 'N' Is_Already_Selected, 'N' Is_Selected_Copy, a.*
from XXPA_STATE_CONST_DTLS_V a, xxpa_state_const_dtls b
where a.child_id = b.child_id(+)
and b.profile_id(+) = :1) QRSLT WHERE PARENT_ID = :Bind_ChildId
it Shows Errors as
## Detail 0 ##
java.sql.SQLException: Missing IN or OUT parameter at index:: 1
could anyone tell what could be the wrong. Do we need to set bind variable in view link Explicitly? or any other alternative.
Its very Urgent.
Regards
Vimal

Hi,
I have faced similar problem some time ago. I could not find any solution except removing bind parameters in where clause. I tried to change binding style but it also didn't work. I think the problem is caused by view link's where clause.

No Signature of Method Error when trying to set Bind Variable Groovy Expr

I am trying to set a Bind variable on my view object to equal the output of a function defined in the the EntityImpl.java that corresponds to that bind variable.
I set the value of my bind variable to be = adf.object.getMyServiceType()
Where the name of the view object I am currently in is called GridSwSoftwareServiceView.xml and the Entity object is called GridSwSoftwareService.java and the EntityImpl file is called GridSwSoftwareService.java.
I am seeing this error:
No signature of method: oracle.jbo.common.VariableImpl$VariableExprValueSupplier.getMyServiceType() is applicable for argument types: () values: []
Does anyone know what this error means?
I was trying to follow an example from this doc: http://www.oracle.com/technology/products/jdev/11/how-tos/groovy/introduction_to_groovy.pdf
Edited by: user10791986 on May 21, 2010 2:50 PM

Looks like a bug... :(
It works fine as a View Object attribute expression but it fails miserably once added as an expression to the bind variable. In this case, here is a work-around:
Define the method as static in your EntityImpl.java :
public static String getMyServiceType() {
return "EBSO R12";
Then access it by fully qualifying it with the package and class :
com.yourpackage.EntityImpl.getMyServiceType()
Edited:
On a second thought, I am wondering if the expression is valid since the Entity hasn't yet constructed at that point.... That explains why it works when made static.

Bind Variable : required - no message, not required - error

hi
Please consider the example application created using JDeveloper 11.1.1.6.0
at http://www.consideringred.com/files/oracle/2012/RequiredOrNotBVarApp-v0.01.zip
It has these View Objects defined
- EmployeesReqNoValueBVarVO which has a required Bind Variable, and where clause "last_name like '%' || :LastNameBVar || '%'"
- EmployeesNotReqNoValueBVarVO which has a NOT required Bind Variable, and where clause "(:LastNameBVar is null or last_name like '%' || :LastNameBVar || '%')"
The Bind Variable in both View Objects does NOT have a value (no default value, not programmatically set, not entered by the user, ...).
This "no value set" aspect could be the result of a "development error", but the resulting observed behaviour is at least "peculiar".
- scenario (sc1) : run "try tryEmployeesReqNoValueBVarVO", see a table filled with rows and NO message about the required Bind Variable
- scenario (sc2) : run "try tryEmployeesNotReqNoValueBVarVO", see "No data to display." in the table and the "Missing IN or OUT parameter at index:: 1" error for the NOT required Bind Variable for a where clause that can deal with null values
- question (q1) How can be explained that scenario (sc1) does not result in an error message about the required Bind Variable (and scenario (sc2) does result in an error message about the NOT required Bind Variable)?
- question (q2) What does the "Required" checkbox for a Bind Variable really mean for Bind Variables used in a where clause of a View Object?
If the described behaviour can be reproduced (using RequiredOrNotBVarApp-v0.01.zip), confirmations are welcome.
(Aspects of these scenario's could be related to forum thread "Bind variable required/not required: strange behaviour".)
many thanks
Jan Vervecken

Thanks for your reply Frank.
Frank Nimphius wrote:
... your query actually is dependent on the existence of the bind variable because the bind variable is used in the where clause part. ...Sure, and the Bind Variable does exist (in both (sc1) and (sc2)).
... This has nothing to do with whether the bind variable value is checked for NULL and if the value it contains is NULL performs an "all you can eat" type of query. Because the existing, NOT required Bind Variable has not been given a value in scenario (sc2), the check for NULL only makes more explicit that NULL is a valid value for the SQL statement.
... Non required bind variables are used in the context of view criteria to avoid missing IN or OUT parameters. ...The "Required" checkbox for a Bind Variable is also available/enabled when the Bind Variable is not used in a View Criteria (in both (sc1) and (sc2)).
... In the case of a view criteria, the VO query may be executed without the view criteria applied and for this reason should not fail only because the defined bind variable is not provided. ...No View Criteria in the scenario's (sc1) and (sc2) I descirbe.
... If you run the query in the tester, you get
(java.sql.SQLException) Missing IN or OUT parameter at index:: 1
and no query is executed at all for EmployeesNotReqNoValueBVarVOSure, that matches scenario (sc2), but the Bind Variable can be configured as NOT required, how can it be missing?
The JDeveloper help page "Create or Edit Bind Variables Dialog - Variable Page" says:
"... Alternatively, you can use the SQL Statement page of the Edit View Objects dialog to enter a parameterized WHERE clause. Note that the bind variables you enter in a parameterized SQL WHERE clause will require a valid value at runtime or a runtime exception error will be thrown. ..."
So, null as a valid value, seems to explain the behaviour in scenario (sc1).
"... In contrast, when you create a view criteria filter condition that references a named bind variable, you can specify whether the value is required or optional. ..."
But, the "Required" checkbox is also available (to uncheck) for Bind Variables that are not used in a View Criteria.
Specifically for the "Required" checkbox the help page says : "... Select if you want to make the value of a name bind variable required for any usage the references the named bind variable. For example, when the value is required (default), all view criteria items that reference the named bind variable will fail to execute unless a valid value is supplied at runtime. Alternatively, you can leave the value not required and use the Create View Criteria dialog to specify whether or not individual view criteria items require the value. ..."
Again, the focus is on View Criteria, although it can also be unchecked (configuring as NOT Required) for Bind Variables that are not used in a View Criteria (which does not seem to be something you should do).
But, still, there is a perspective here that makes this possibly very confusing:
- a View Object where clause with a required Bind Variable, no value set --> results in rows, and NO message about a missing value
- a View Object where clause with a NOT required Bind Variable, no value set --> results in no rows, and a message about a missing value

Getting a bad bind variable error while compiling a custom form in R12

Hi,
I am getting a bad bind variable error while compiling a custom form.
I tried setting the forms_path variable and I am still getting the error. Can anyone please suggest what can be done?
DECLARE
BEGIN
IF :parameter.p_line_ship_to = 'T'
THEN
IF :SYSTEM.cursor_item = 'LINE.SHIP_TO'
THEN
:parameter.lov_num_param1 := :line.ship_to_customer_id;
oe_lines.ship_to ('WHEN-VALIDATE-ITEM');
:parameter.lov_num_param1 := :line.ship_to_customer_id;
END IF;
:parameter.p_line_ship_to := 'F';
END IF;
END;
I am getting this error:
Bad bind variable 'parameter.p_line_ship_to'

The Parameter is not defined in the form.. But, this form is already been compiled and deployed.. I have to make some changes to the form and tried to compile it, when i am getting this error. Is it possible that the parameter would be defined in some other form or can this error be due to some other reasons?
Thanks in Advance.

Problem in setting bind variable

Hi Frank,
Thanks, I think thats the gotcha...
setting the bind variable to required causes the dialog to appear...
Not sure though if this is a bug or something..

Error bind variable with "like %" clause ?

Hello everybody;
I would like to know how to do a like clause to bind variables, with this code i obtain 'ORA-00933: SQL command not properly ended' error
v_query:= 'UPDATE ' || collection(i) ||' SET REF_PLAN=:quatre_champ WHERE FAM_SIM like ''%'':prem_champ''%'' AND PRISE_V1P like ''%'':deux_champ''%'' AND BROCHE_V1P like ''%:trois_champ%''';
                              EXECUTE IMMEDIATE v_query USING quatre_champ,prem_champ,deux_champ,trois_champ;Maybe my " ' " are in a bad positions ?
Thanks for your help, regards.

Hi,
try this
v_query :=
         'UPDATE '
      || collection (i)
      || ' SET REF_PLAN =:quatre_champ WHERE FAM_SIM like'|| '''%:prem_champ%'''
      || ' AND PRISE_V1P like' || ''' %:deux_champ%'''
      || ' AND BROCHE_V1P like'||''' %:trois_champ%;'''
Of course not tested
Any efforts to give sample data and help us recreated the problem will be appreciated.
Cheers!!!

Error with concurrent users- Activation Passivation Bind variable ?

I have a programmatic view object based on procedure call that returns a ref cursor.
Application Module has a function that exposes get Method for this View object using client interface.
Everything works good until many users call the same Method ,for many concurrent users i got the below error intermittently :
JBO-27122: SQL error during statement preparation.
Attempt to set a parameter name that does not occur in the SQL: bussId
For 1 or 2 users this works perfectly fine.
bussId is a bind variable defined at View object of type Array.
I understand this should be because of activation/passivation as many users calling same function comes to picture.
To solve this I overloaded activateState/passivateState in View implementation for the bind var.
But i don't see those methods getting invoked ever.
I also enabled connection pool/AM pool and kept the default pool values high enough for concurrent users.
Nothing works .
Appreciate any help in this regard.
