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

Thanks,
Srikanta

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]. Please let us know if you need any help.

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.

How to fill more values in one field (JSP / HTMLX)

When I want to fill one value in a field on a JSP page, I enter:
value="<%=someClass.getSomeValue() %>"
How should I enter more values (e.g. street, city, postal code, country) in one field?
I tried to put those fields together, so I do one getAddress() call, but the output is (initial screen - supposed to be empty) null null null null
When I enter a customer, the field works ok (no null values).
TIA,
Mylene

JSP:
<hbj:inputField
id="CustomerAddressInputField"
type="STRING"
maxlength="10"
value="<%=quotationHeader.getCustomer().getAddress().getAddress() %>"
design="STANDARD"
... %>"
getAddress():
@return String (complete address / positioning
pCode unsure!)
public final String getAddress()
return (street + " " + pCode + " " + city + " " + cCode);
This is what returns null null null null
What I want (if possible) is to change the getAddress() in the JSP in subsequent getStreet() - add space - getPCode() - add space - getCity() - add space - getCCode()
That will not result in null values - I hope.
But just putting those calls in the string between the
value ="<%= and the %>" tags doesn't seem to work!
TIA,
Mylene

How to fill column value of a matrix with specific color when there is no value in that specific cell?

Hi All,
I need to create a 5/5 matrix in SSRS report. The data will be :
Col_Side   Col_Header   Col_data
1                  1                1
1                  1                 1
1                  2                1
1                  5                1
1                  5                1
1                  5                1
2                  3                1
2                  5                1
3                  1                2
3                  1                2
3                  1                2
4                   2               1
4                   4               1
5                   1               1
5                   1               1
5                   5               1
So, the matrix column will be Col_Header and matrix row will be Col_Side and count(Col_data) will be on the data.
Finally, it will create a 5 by 5 matrix with Count(Col_data) as its data for each combinations. If there is no combination (for ex: in the above data we do not have no combination of (1,3) , (1,4) , (2,1) etc..) then the matrix will be filling that corresponding
cell with zero.
Here I need to fill the cells with some colors based on some criteria.
I need to fill (5,3), (5,4), (5,5) combination with "Red" color. Like this , I need to give different colors in each of the cells. Here, (5,5) combination will be having 1 in its cell. (5,4) and (5,3) will be having zero in its corresponding
cells. I 'm trying to fill all the 3 cells with "Red" color. But, I am able to fill only (5,5) with "Red" color. Since the other 2 cells (5,3) and (5,4), has zero in their cells, it will not fill the cells with "Red" color.
How can I fill those two cells (5,3) and (5,4) with red color?
I know this is very vague. I have no option to give the picture here..
Please suggest

Hi Julie,
According to your description, there is a 5/5 matrix with three fields: Col_Side, Col_Header, Col_data. You drag Col_Side field to Rows, Col_Header to Columns and Col_data to Data, then filling blank cells with zero using expression. Now you want to fill
(5,3), (5,4), (5,5) cells with red color using expression, but it has no effect on cells (5,3) and (5,4).
According to my test, the expression has on effect on cells (5,3) and (5,4) since there is no corresponding data and the cells are blank. As a workaround, we can insert data for cells (5,3) and (5,4) in dataset, then use expression by following steps:
In the dataset, insert two sets of data (5,3,0), (5,4,0).
Right-click the cell of data, click Text Box Properties.
Click Fill in left pane, click (fx) button, then type the expression like below, then click OK.
=iif(Fields!Col_Side.Value=5 and Fields!Col_Header.Value >=3 ,"red","white" )
The following screenshot is for your reference:
If you have any more questions, please feel free to ask.

How to insert object values into table.

Hi All,
I have a problem with passing java object to procedure. Procedure is running properly when I execute in oracle,but it is not executing when I call from Java.
I am getting Error :
java.sql.SQLException: invalid name pattern: Pkg_Bulk_Insert.ITW_EMP_OBJ_ARRAY
 at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java)
 at oracle.jdbc.oracore.OracleTypeADT.initMetadata(OracleTypeADT.java)

 at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java)
 at JavaObjectToOracle.main(JavaObjectToOracle.java:31)
Here I am copying my procedure,oracle version is 9i.
Package specification:
CREATE OR REPLACE PACKAGE Pkg_Bulk_Insert AS
TYPE ITW_EMP_OBJ_ARRAY IS VARRAY(20) OF VARCHAR2(200);
PROCEDURE BULK_INSERT_TEST(strTable IN ITW_EMP_OBJ_ARRAY);
END Pkg_Bulk_Insert;
package body:
CREATE OR REPLACE PACKAGE BODY Pkg_Bulk_Insert AS
PROCEDURE BULK_INSERT_TEST(strTable IN ITW_EMP_OBJ_ARRAY) AS
i BINARY_INTEGER;
BEGIN
FORALL i IN 1..strTable.COUNT
INSERT INTO TEMP(NAME)
VALUES(strTable(i));
COMMIT;
END BULK_INSERT_TEST;
END Pkg_Bulk_Insert;
Here I am invoking the procedure:
DECLARE
x Pkg_Bulk_Insert.ITW_EMP_OBJ_ARRAY;
BEGIN
x := Pkg_Bulk_Insert.ITW_EMP_OBJ_ARRAY('A','B','C');
Pkg_Bulk_Insert.BULK_INSERT_TEST(x);
DBMS_OUTPUT.PUT_LINE('AFTER INSERTION');
END;
Please any body can help me on this regard.

Your PL/SQL seems reasonable.
My suspicion would be that the oracle.sql.ArrayDescriptor.createDescriptor class only supports persistent collection types, i.e. those declared at the schema level with CREATE TYPE.

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?

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 =

Implement Object Value Selector

Hello,
We are implementing ESS Business Package 1.0 on EP7.0 and in Travel and Expense we are using 'Switch Personnel Number' service which allows the user to select a personnel number and create expense reports for them...but currenlty it does not have a OVS which will allow them to select an employee from the list rather than entering it....please let me know how to implement it...
Any help would be highly appreciated.

Hi Anil,
Refer to the following links to implement OVS:

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.

How to fill or bind data using Value Node in Tree Node

Hi Gurus,
Can anybody help me on how to fill data or bind data using Value Node in Tree Node View. I know how to create Tree Node but not able to show value on the UI in Tree View.
Can u please let if anybody has done it?

In the above code iv_bo , lv_value_node will be the actual object of the second node or leaf node here, which will have the same structure of parent node along with data. After/before this, you would need to build table and refresh in do-prepare_output of IMPL class.In the above code iv_bo , lv_value_node will be the actual object of the second node or leaf node here, which will have the same structure of parent node along with data.

Also the EH_ONEXPAND has to be implemented and event handled in DO_HANDLE_EVENT. But this expand event has to be delegated to context node directly as CL_BSP_WD_CONTEXT_NODE_TREE will already have the implementation.
