About dynamically setting bind variable in LOV View

Hi,
I have a LOV VO for an af:SelectOneChoice field in the page.
The LOV is depended on an SQL statement in which there is a bind variable in the where clause.
When I open the page, I set the bind variable by using VO.setNamedWhereClauseParam in the prepareSession method in the application module, followed by VO.executeQuery();
The problem is, the af:SelectOneChoice is blank. Why?
If I do not use the bind variable in the SQL, I can see rows in the af:SelectOneChoice field.
When is the proper time to populate the LOV? And where should I put the code for populating the LOV?
I am sure that the VO is populated, because after I executeQuery, there are many rows in the VO.
Thanks
Stephen

Hi Franky,
Yes, when I set a default value for the bind variable, everything is OK.
But I want the bind variable dynamically be set when the AM is initiated. Is there a way to do that?

Setting bind variable for a view object from the Managed Bean

Hi,
i am using JDeveloper 11g, i have to create LOV in the JSF. To show the LOV, it has to populate data using View object and its query parameter need to be sent from the Managed Bean.
For the View object i want to set the bind variable parameter from the managed bean value. bename is stored in a managed bean (session scope)
#{beantest.bename}
But it gives the following exception.
JBO-29000: Unexpected exception caught:
org.codehaus.groovy.control.MultipleCompilationErrorsException,msg=startup failed, Script1.groovy: 1: expecting '!',found '{'@ line1, column 2.
I have followed the link http://kr.forums.oracle.com/forums/thread.jspa?threadID=615474 like Frank wrote on 8.2.2008:

Hi,
a bind variable in a VO needs to be exposed as an executeWithParams operation in the pageDef file. Just add a new action binding to the pageDef file (context menu) and select the executeWithParams operation on teh VO. Then in the argument field, reference the managed bean property for the value

Dynamically assign value to bind variable in a view object before pageload

I found that it is extreamely hard to find an example to assign the bind variable in View object at runtime using a data attribute defined in Human task activity. Most of the available samples use a Literal value to do the assignment. In my case, I want to dynamically display the content by assigning the data attribute in Human task to the bind variable in view object before a pageload.
I do not want to bind the view object to some command component to click a button or link in order to make it work (Unnecessary components in my page).
The issue is how to access the data attribute in Human task in the java code of client interface in AppModule? or is there a way that I can access the data attribute in Groovy script expression of the bind variable? or if I can access the process data object defined in my BPM process to do the assignment at runtime?
Really need help on the issue, and I cannot believe that it is so hard to accomplish.
Thank you very much,

How to share a bind variable across multiple view objects?

Hi, Can someone tell me if it's possible to share a bind variable among multiple view objects within an application module? My web page displays data from different VOs on different regions. But all data should be controlled by the same bind variable, which appears in all queries. How can I achieve this?
Please help.

Best to state your JDev version, and technology stack (eg. ADF BC) when posting.
I can think of 2 approaches.
1) Create a parent VO based on SELECT :bindVar FROM dual, then create links between your other VOs and the parent
2) Create a AM client interface method that programatically sets the bind variable in each VO.
Can you specify your use case? This one tends to come up when discussing effective from/to dated queries.

Setting bind variable value programmatically for master and child VO's

Defined following BC:
Serv VO - Master VO, has Bind_cNum (bind variable)
ServDetail VO - Child VO, has Bind_cNum2 (bind variable)
ServViewLink VL - View link between Serv VO & ServDetail VO
in AMModule Impl have custom WS:
public List<ViewRowImpl> getMyServices(String cNum)
List<ViewRowImpl> result = new ArrayList<ViewRowImpl>();
ViewObjectImpl vo1 = getServ(); //Master VO
vo1.setNamedWhereClauseParam("Bind_cNum", cNum);
vo1.setForwardOnly(true);
ViewObjectImpl vo2 = getServDetail(); //Child VO
vo2.setNamedWhereClauseParam("Bind_cNum2", cNum);
vo1.executeQuery();
while (vo1.hasNext()) {
result.add((ViewRowImpl)vo1.next());
return result;
I am passing same cNum parameter to both Serv VO (Master VO) and ServDetail VO (child VO) as above. (this is in addition to view link bind variable :Id)
It shows in the logs that it is setting the values correctly:
<ViewRowSetImpl> <setNamedWhereClauseParam> [382] Serv ViewRowSetImpl.setNamedWhereClauseParam(Bind_cNum, 11771370)
<ViewRowSetImpl> <setNamedWhereClauseParam> [383] ServDetail ViewRowSetImpl.setNamedWhereClauseParam(Bind_cNum2, 11771370)
<ViewRowSetImpl> <doSetWhereClauseParam> [383] Serv ViewRowSetImpl.doSetWhereClause(-1, Bind_cNum, 11771370)
<ViewRowSetImpl> <execute> [385] Serv ViewRowSetImpl.execute caused params to be "un"changed
<OracleSQLBuilderImpl> <bindParamValue> [394] Binding param "Bind_cNum": 11771370
<ADFLogger> <addContextData> Execute query
-- when executing view link
<ViewRowSetImpl> <setParamValues> [425] ServViewLink_0 ViewRowSetImpl.setParamValues params changed
<ViewRowSetImpl> <doSetWhereClauseParam> [426] ServViewLink_0 ViewRowSetImpl.doSetWhereClause(-1, Bind_cNum2, null)
<ViewObjectImpl> <bindParametersForCollection> [436] For RowSet : ServViewLink_0
<OracleSQLBuilderImpl> <bindParamValue> [437] Binding null of type 12 for "Bind_cNum2"
<OracleSQLBuilderImpl> <bindParamValue> [438] Binding param "Bind_Id": 5018
from above log, when ServViewLink_0 is executed, it is changing Bind_cNum2 bind variable to null.
how can i pass same bind variable value to both Master and Child view objects from AM Impl.java

Try executing the vo1 query before setting the bind variable for vo2, then execute the vo2 query (if that's what you want to do).

Dynamic default bind variable

Hi!
I have a bind variable in a view object, where i want the default variable to be a text version of now (timestamp) in the format 'dd-mm-yyyy HH:mm'.
I have tried to look at a solution using Groovy Expression, but I cannot figure out how to do it.
Please HELP!!!! :-)
/Casper

Hi,
You can create a method in your viewObject implementation class and retrieve the value from there, using groovy.
I have used something similar to retrieve a dynamic parameter in an Entity validator.
Have a look here: http://www.gabrielsideras.com/2010/10/03/groovy-display-dynamic-error-message-in-validator/
and here: http://formattc.wordpress.com/2010/04/02/custom-java-bind-variable-in-a-where-clause-of-an-adf-view-object/

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.

You can set the bind variable on VO by overriding prepareSession() method in Application Module check this http://docs.oracle.com/cd/E37975_01/web.111240/e16182/bcservices.htm#sthref357

Dynamically Setting a Variable from a Connection String that has been set by a Config File

Hi Guys
I'm setting up a Master / Slave (Parent / Child) dtsx environment but I'm unable to work out how to dynamically set a variable in the Master dtsx from a connection string that has had its value set by a config file. I'm sure it's possible.
Below is the what I'm hoping to achieve. I've set up everything apart from the highlighted section.
Any ideas?

First, what version of SQL Server are you using?
You could switch the problem around. You could set the value of a variable from the config file, then it is easy to use that variable as the connection string source for your connection manager. At the same time you can use a parent variable
configuration to map that variable to variables in your child package.

Is it possible to set bind variable for picklist?? for messageChoice

we are trying to develop one new page in local JDeveloper.
we have requirement for passing a bind variable to a picklist. is it possible?
Item Type : messageChoice
Query:
SELECT DISTINCT TO_CHAR (effective_date, 'YYYY') TYPE
FROM pay_assignment_actions a, pay_payroll_actions b
WHERE a.payroll_action_id = b.payroll_action_id
AND assignment_id =
(SELECT assignment_id
FROM per_assignments_x
WHERE person_id = :person_id AND primary_flag = 'Y'
AND assignment_type = 'E')
AND a.action_status = 'C'
AND b.payroll_action_id IN (SELECT payroll_action_id
FROM pay_payroll_actions_v
WHERE action_type IN ('P'))
AND b.payroll_action_id IN (SELECT payroll_action_id
FROM xxilo_pre_payments)
ORDER BY 1 DESC
processRequest() code:
PayslipAMImpl am=(PayslipAMImpl)pageContext.getApplicationModule(webBean);
YearPicklistVOImpl yvo=(YearPicklistVOImpl)am.getYearPicklistVO1();
Number t = new Number(pageContext.getEmployeeId());
yvo.setWhereClauseParams(null);
yvo.setWhereClauseParam(0,t);
for this query & code we are getting
ERROR:
java.sql.SQLException: Missing IN or OUT parameter at index:: 1
if we hardcoded person_id in query to some value then we are getting results without any error.

user603084 ,
In the query you have specifies bind variable as :person_id , but in your VO execution code you are setting value for bind variable :1
yvo.setWhereClauseParam(0,t);
You need to change the bind variable in query , like :1
and then execute the query of VO, as you have done. Also do executeQuery, after setting bind variables.

I have created an LoV with a bind variable which executes correctly when run independantly of a form
When I attach the loV to a form I get prompted to :-
"Set the binding(s) for the bind variable(s) defined in the lov"
How do I do this ?
All replies gratefully recieved, thanks in advance

How to properly set bind variables

Dear All,
I am currently confused about how to properly set my Bind Variables
I have this view using HR standard schema
Select *
from Employees
where EMPLOYEE_ID = :EMP_IDI somehow see three options on how to use this bind variable in an application module.
Option 1:
ViewObjectImpl view = this.getEmployeesView();
VariableValueManager vm = view.ensureVariableManager();
vm.setVariableValue("EMP_ID", value);
view.executeQuery();Option 2:
ViewObjectImpl view = this.getEmployeesView();
view.setNamedWhereClauseParam("EMP_ID", value);
view.executeQuery();Option 3:
EmployeeViewImpl empView =this.getEmployeesView();
RowSetIterator it = empView.createRowSetIterator(null);
empView.setEmployeeId(value);
empView.executeQuery();Question is which is which and what should I use?
JDEV 11G PS3

I use is this
DCIteratorBinding iteratorStatus = Util.getIterator("NameIterator");
operationBinding.execute();
Util is reserved in a class.
public static DCIteratorBinding getIterator(String iteratorName){
return getDCBindings().findIteratorBinding(iteratorName);
}
