Hi Srikanta,
you can use object value help selector in table by creating a singleton node attribute by this you will make sure that one row's value is not affected by other row's value selection for object value help please refer to this wiki article [Value Help - Object Value Selector|http://wiki.sdn.sap.com/wiki/display/WDJava/ValueHelp-ObjectValue+Selector].

Object Value Selector (OVS) Tutorial Help!

Hi,
I am working on the advanced input help: The Object Value Selector (OVS) tutorial. I downloaded the ready- to- use from SDN and tried to deploy and run it. I don't know what user name and password to use in order to maintain JCo to create the MODELDATA and METADATA in local J2EE engine. In NetWeaver Developer Studio, the models AdRFCFlightListModel, Model Classes, and the BAPIs have been created by SDN already, so I don't really know what username and password to use. If anyone could help me with this, I would greatly appreciate that.

Problem running Object Value Selector

Hi,
We have implemented OVS for GetFlightList BAPI. We are able to get the data on the OVS selector. But once we click on a particular record of the table, the value is not passed to the base control and we get ClassCastException in applyResult() method of the listener.
The code is pasted below.
public void applyResult(IWDNodeElement applicationNodeElement,
 IWDNodeElement queryOutputNodeElement) {
try
IPrivateOVS_testView.IFlight_dataElement ovsCallerNodeElement =(IPrivateOVS_testView. IFlight_dataElement) applicationNodeElement;
The exception thows on this line of the code.
Any help?
regards,
Deepika

I am still getting the same Exception.I am explaning the scenerio:
I created a set of Flight_data attributes in the custom controller and mapped to a similar set in the view controller to fix the error.The listener is implemented in the Custom controller.On selecting a row from the OVS table i get the CastClass Exception in the applyResult()method of the listener at the following point of code:
IPublicTestOVS_Custom.IFlight_dataElement ovsCallerNodeElement =
 (IPublicTestOVS_Custom.IFlight_dataElement)
 applicationNodeElement;
The exception is given below:
java.lang.ClassCastException

How to fill Object Value Selector

Hello All,
I want to fill values for my value help node dynamically. Where should I write the code. I mean in which Method I should write.
Any help on this is highly appreciated.
Regs,
Venkat

Venkat,
if you want to get the help, before view is shown to user , then write the code in WDDoInit() , if you want to get the help on performing any action lets say, on clicking button then
create one action , bind this to the OnAction of button , then you can write the code in the action event handler of that button; so value help will be recieved on clicking the button.
if you want to refer any tutorial , here it is:

let me know if you have any problem

Object Value Selector in Webdynpro

Hi I'm trying to use in OVS in my WebDynpro Application,
I'm trying to create a Custom Controller to implement helper context, where do i get the APIs for WDValueServices.
When I try to declare a method in the custom controller with return type com.sap.tc.webdynpro.progmodel.api.IWDOVSContextNotificationListener local dictionary doesn't show this type. Can anyone help me ?
Raj.

Hi Raj,
the requested type is not a dictionary type, it's bloody plain old Java type Please select the "Java Native Type" radio button when editing the "type" property of the corresponding value attribute, press "Browse...", then type IWDOVSContext.. in the following search dialog and select the listener in the list below.
Hope that helps.

Stefan

 ovsStartUpAttributes,
 wdThis.wdGetTestOVS_CustomController().getOVSInputNode(),
 wdThis.wdGetTestOVS_CustomController().getOVSOutputNode(),listener);
How do we get/give the provider (first parameter)? I have put it as "Flight Selection". Will this make any difference?
Exception message is below

Portal Runtime Error while clicking on value selector

Hi,

If I assign the same role to my portal user(Admin rights) working fine...but if I assign it to end users...not accessible on popup and giving portal runtime error.
Currently i have assigned standard "eu_role" to the end users...Do I need to give any special permissions to some of end users?
Appreciate all your help in this regard.

I will connect to server and monitor the remote server JVM , There is a object of User, I want to change its value by the Java Debugger Interface by client.
so how to set its value by the client, and I can not got the User bean at client.
I know the basic type filed value changed as follows:
Value newValue = vmMachine.mirrorOf("change var value");// this field is a string.
stackFrame.thisObject().setValue(field, newValue);
But a Object , how can I change its value.
Thanks Advanced.

ObjectReference.setValue() is the method for chaining the value of an Object's field. First you need to find the specific Object you want to change, though.

GlobalContainer object values acessed among UDF's in message mapping ?

hi
i have scenario where i am using globalContainer variable functionality in my message mapping.
in edit java section
String usr;
Container container ;
GlobalContainer globalContainer ;
intialize usr = "";
in First UDF
String inlogin_sess = " ashutosh test value" ;
globalContainer.setParameter(usr,inlogin_sess);
return any value :
now if i create another 2nd UDF and use :
String out =globalContainer.getParameter(usr);
return out ;
now 2nd UDF is giving null pointer exception...
for testing the code functionality..
IF i use the SET and GET in 1st UDF :
globalContainer.getParameter(usr);   in 1st UDF than it is working sucessfully...
globalContainer.setParameter(usr,inlogin_sess);
String out = globalContainer.getParameter(usr);
return out ;
in help.sap it is mentioned that Globalcontainer objects values can be fetched   among UDF's in one message mapping....
[http://help.sap.com/saphelp_nw04/helpdata/en/0f/80243b4a66ae0ce10000000a11402f/frameset.htm]
i have gone a lot of thread in sdn where Global container are used like sequence no creation etc, but every where the
GET and SET are used in SAME UDF...
any clue where is leak..
Regards,
ashutosh R

Hi Abhishek
Your point is legimate, but for my their is no such issue..
even i try to use it as :see image..
[http://www.screenshots.cc/show.php/14137_GlobalVariable.JPG.html]
UDF1 :
globalContainer.setParameter(usr,inlogin_sess);
return any value :
and in UDF2
String out = globalContainer.getParameter(usr);
return out ;
mainting the sequence
My concern is object globalContainer is local in UDF1, so it will through nullpointer ,if we try to access in UDF2.
if we declare globalContainer   in edit jave -GlobalVariables also, still it is having the error..

How to Catch the Event when a Row is Selected in Extended value Selector

Hi All.
I Want to Call the Action when a perticular row is selected in Extended value Selector.
How can I do it
Thanks & Regards
Kiran

Hi Kiran,
Create a seperate view with the table of records same u are showing EVS because with EVS it is not possible to raise any event.
So add ths view to a seperate window and open that window instead of EVS .So here you can raise an event becuse it a view.
