Data binding in check_box in the WAD

Dear Gurus,
I searched on the forum and did not find any body having the same issue as mine...so here is my issue:
I created a web template thanks to the WAD. I want to add a check box list containing the characteristics in the result of a query.
Here are the steps:
- add the check box list in the template
- as data provider : my query
- in the characteristic field : the characteristic in the drill down of my query (actually it is a navigational attribute)
When I run the report, I get the data from another characteristic....
what is really strange is that, the WAD offers me the right characteristic...
Any idea ??
PY

Hi Michael
Thanks for the feedback, but I do not see the link between the 2 issues. Could you be more explicit ?
The OSS note you mention deals with the read mode of master data.
My issue is linked to the fact that the checkbox_group_item does retrieve the value of the characteristic I asked for, but from another chararcteristic in the web template...
The only link I would see is that BW will feed the checkbox with the first available characteristic in the buffer...
Another idea ?

How can I set the data binding between Web Dynpro & Database table

Dear friend,
I am a beginner of Web Dynpro. I want to develop my simple project like these:
1. Create my own database table via Dictionary Project such as TAB_USER and have 3 fields: USER_ID, USER_NAME, USER_POSITION and I have already deployed & archived it.
2. Create my own Web Dynpro Project, and create the input fields as User ID, User name, User position and icon 'Save' on the selection screen and I have deployed it already.
For the process, I want to input data at the screen and save the data in the table, please give me the guide line like these:
1. How can I set the data binding between Web Dynpro and Database table ?
2. Are there any nescessary steps that I will concern for this case?
Sorry if my question is simple, I had try to find solution myself, but it not found
Thanks in advances,
SeMs

Hi,
You can write your own connection class for establishing the connection with DB.
Ex:
public class ConnectionClass {
static Connection con = null;
public static Connection getConnection() {
try{
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/TSPAGE");
con = ds.getConnection();
return con;
}catch(Exception e){
return null;
You can place the above class file in src folder and you can use this class in webdynpro.
You can have another UserInfo class for reading and writing the data into the DB .

The data binding isn't working, what have I done wrong?

I'm writing a very simple WPF app, one view. I've got a few models defined for the small handful of tables this app works with. I'm making some sort of boneheaded mistake, but I can't see what it is. I'm trying to bind to a property of one of the model
classes I've define, to a textbox in a stackpanel. Here's the XAML:
<StackPanel Orientation="Horizontal" Margin="0, 5" DataContext="{Binding cvsSpecMapping}">
<TextBlock Margin="10,0,5,0">Specimen Mapping: </TextBlock>
<TextBox x:Name="txtHl7SpecMap"
Text="{Binding HL7SpecimenTypeName}"
ToolTip="{Binding HL7SpecimenTypeName}"
MinWidth="50"
MaxWidth="100"
MaxLength="250" />
</StackPanel>
Earlier in the same XAML file I've got the following collection view source defined in the windows' resources:
<CollectionViewSource x:Key="cvsSpecMapping" />
This isn't rocket science. Here's the model class definition. I'm removing all but the relevant property:
using System;
using System.ComponentModel;
using System.Runtime.CompilerServices;
namespace SpecMapException.Models
* This class I am interested in knowing what properties change.
* Also note that the properties in this class do NOT represent all of the properties
* in the Prism.SpecimenMapping table. It only represents what this application has
* to store.
public class SpecimenMapping : INotifyPropertyChanged
private const int MAX_HL7SPECIMENTYPENAME_LEN = 250;
#region class properties
private string _hl7SpecimenTypeName = "";
public string HL7SpecimenTypeName
get { return _hl7SpecimenTypeName; }
set
if (value != _hl7SpecimenTypeName)
_hl7SpecimenTypeName = EnforceMaxLength(value, MAX_HL7SPECIMENTYPENAME_LEN);
NotifyPropertyChanged();
#endregion //class properties
#region local routines
private string EnforceMaxLength(string PassedValue, int MaxLength)
if (PassedValue.Length <= MaxLength)
return PassedValue;
return PassedValue.Substring(0, MaxLength);
#endregion
#region PropertyChanged code
* The usual property changed code.
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged([CallerMemberName] String propertyName = "")
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
#endregion
And lastly here's the relevant code which I've put into the windows Loaded event:
Models.SpecimenMapping sm = null;
private void Window_Loaded(object sender, RoutedEventArgs e)
var cvsSpecMapNames = (CollectionViewSource)(this.FindResource("cvsSpecMapping"));
cvsSpecMapNames.Source = sm;
So what is the mistake that I've made? Why isn't the data binding to the textbox txtHl7SpecMap working?
(I'm using VS 2013, .NET 4.5.)
Rod

cvsSpecMapping is a resource and not a property so you should set the DataContext using the StaticResource markup extension instead of Binding:
<StackPanel Orientation="Horizontal" Margin="0, 5" DataContext="{StaticResource cvsSpecMapping}">
Also, the Source property of a CollectionViewSource is supposed to be set to a collection:
private void Window_Loaded(object sender, RoutedEventArgs e)
sm = new Models.SpecimenMapping();
var cvsSpecMapNames = (CollectionViewSource)(this.FindResource("cvsSpecMapping"));
cvsSpecMapNames.Source = new List<Models.SpecimenMapping>() { sm };
You may also want to set a default value of the HL7SpecimenTypeName property to confirm that the binding actually works after you have done the above changes:
public class SpecimenMapping : INotifyPropertyChanged
private const int MAX_HL7SPECIMENTYPENAME_LEN = 250;
#region class properties
private string _hl7SpecimenTypeName = "def....";
public string HL7SpecimenTypeName
get { return _hl7SpecimenTypeName; }
set
if (value != _hl7SpecimenTypeName)
_hl7SpecimenTypeName = EnforceMaxLength(value, MAX_HL7SPECIMENTYPENAME_LEN);
NotifyPropertyChanged();
Hope that helps.

WAD: anyway to bind each tab of the tab page web item to different query?

WAD: anyway to bind each tab of the tab page web item to different query?
We check the properties of the tab page web item, but can't find we can bind the tab to some query.
Any idea?
Thanks!

will try to write as much detail steps as i can...
drag tab page web item in wad window
go to its properties
for e.g. u currently have only 1 tab page
than name tab page1 as p1
hit button with ..
this will let u add new heading to tab page 2
likewise save heading of 4 tab pages in properties of tab pages
now choose container web item
drag it in tab pages window
assign seperate analysis item in each container item
assign seperate queries in each analysis web item.
assign container1 to tab page1
assign container2 to tab page2
assign container3 to tab page3
assign container4 to tab page4
and their heading viceverssa
save it execute it
now u will have 4 queries in 4 container item and uc an see that in different tab pages.

Displaying header with data binded to the R/3 system

hi
I have developed an application which uses Interactive form to generate the Invoice PDF by getting data from back end system R/3.
Now my problem is that the Header which I need to display contains some data binded with the back end system and that the Header needs to be displayed on each and every page of the Invoice.
I need to know how can we set the header so that the header is displayed on each page with the data binded to the back end system.
Immediate help would be appreciated.
Thanks and regards,
kris

Hi Gopi,
There is a limitation for your requirement.The runtime data will not change in each page or it will be blank in case of header.
I have used an alternative for the forms designed from SFP .I have called the PDF in a loop in the driver program. Then a new pdf will generated for each case.
May be the alternative is assign the values through scripting.

Where are the data-binding frameworks for Oracle Objects?

Oracle offers a few different options for data-binding frameworks to Oracle relational data. Amongst them they include TopLink and the Oracle Application Development Framework (ADF)in JDeveloper 10G. J2EE also offers the EJB standard framework. Both of the Oracle data-binding frameworks appear to work well with relational data but fail miserably when one tries to work with a fully fledged Oracle Object-Relational schema. I have spend much time with ADF but have not been able to create successful bindings to Objects with nested complex objects (such as a 2-level nested object) or objects containing nested tables. TopLink will not even touch Object tables.
Have other people being more successful with this? Do we have to implement our own data binding framework? Does Oracle plan on improving these frameworks to fully support Oracle Objects?

TopLink Runtime supports both fully fledged OX mappings and nested complex objects. These mappings can be setup in the code.
TopLink ADF design time however currently does not have support for OX mappings.
Hope this helps,

How to find and replacing the path (url) given for data binding from type 'datasocket'

Hi everyone,
I'm sorry to pose this question as my own knowledge is still very limited.
I have an assignment (bachelor level). We were asked to adjust a plc program in step7 so that multiple of an existing sequence could be run indepently.
The settings for that sequence are controlled by labview. Sensor data is also viewed in labview.
There is an existing labview VI that was made by someone else before us. It uses 'Datasocket' type for data binding. Because we would like to adjust this VI to be used with the other sequences, we would like to change the original path or URL quickly, as in a 'Find&Replace' solution. Yet the find and replace only works for objects or text, not entries in the properties.
Can someone please tell me if there is a way to do is, without having to use shared variables, as we are not at all known with this type.
Many thanks,
Niels

Dear Niels,
Please find the attached example. I placed 5 controls on the front panel, all with a data socket URL (control 1 = URL1, control 2 = URL2 etc). Through property nodes I did the following;
- I got a reference to the front panel
- with this reference we can get an array of references to the controls on this front panel
- one by one we will read the references and check the data socket URL from the control, we compare this with the URL we are searching
- if found, stop we will use the reference to write a new URL to the control.
Please notice the default values of the controls; it is set to search for URL3 and replace this with URL10, run the VI once and you will see that happening. I also included a sting indicator which will show you the label of the control which we find. Also a Boolean indicator in case we were not able to find the URL.
I downsaved the VI to 8.6, I'm not sure in which version you are working, if you have 8.6 or higher you are able to open it. Hope this brings you further,
Best regards,

Data binding working ... now a question about the variables

I wrote a small app based on the example (below) from sapui5.hana.ondemand.com.
My question pertains to anyone else that has data binding working and has tried to do something like the text in red.
When stringing together "variables" like the ones highlighted in below ... if I do something similar all I get on the screen is the actual text, ie {Width} instead of the value that should replace that. If I get rid of the extra text and just have the variable in " " I get the correct value displayed for the "variable"
Anyone else ran across this?
-Mike
var header = new sap.m.ObjectHeader({
title : "{Name}",
number : "{Price}",
numberUnit : "{CurrencyCode}",
statuses : [
new sap.m.ObjectStatus({
text : "Some Damaged",
state : "Error"
new sap.m.ObjectStatus({
text : "In Stock",
state : "Success"
attributes : [
new sap.m.ObjectAttribute({
text : "{WeightMeasure} {WeightUnit}"
new sap.m.ObjectAttribute({
text : "{Width} x {Depth} X {Height} {DimUnit}"
new sap.m.ObjectAttribute({
text : "{Description}"
new sap.m.ObjectAttribute({
text : "www.sap.com",
active : true,
press : function () {
sap.m.URLHelper.redirect("http://www.sap.com", true);

Thanks for the reply Chandra,
To clarify a bit more, I have a list object and have successfully been able to bind a model to it. When I create a list item to put in the list I can display the correct values using the same syntax as above, ie {Width}
So I am not binding the model to the items in the list rather to the list itself then referring to fields that are available in the model using the syntax {Width} ... and this works fine ... until I try and add some additional text like {StgeBin} in the example below (I am including myHeader in the list that has a model bound to it):
var myHeader = new sap.m.ObjectHeader({
        title : "Bin # {StgeBin}",   //This shows the text --> Bin # {StgeBin} ... rather then Bin # 123 (which is what I want)
        //title : "{StgeBin}",        This works and will show the bin number as I expected ie 123
        statuses : [
          new sap.m.ObjectStatus({
            text : "Some Damaged",
            state : "Error"
          new sap.m.ObjectStatus({
            text : "In Stock",
            state : "Success"
        attributes : [
          new sap.m.ObjectAttribute({
            text : "{StgeLocDesc}"
          new sap.m.ObjectAttribute({
            text : "{Material}"
          new sap.m.ObjectAttribute({
             text : "{MaterialDesc}"
I took this example right from the SAPUI5 documentation and it works great, just can't add additional text inline with my variables.

Getting at the data binding for table rows in ADF/UIX

At the highest level, I'm trying to figure out the best way to get spreadsheet-like behavior in a table where some of the cells are editable. The table cells were created using the "model=${uix.current.<columnName>}" mechanism.
I've been able to specify event handlers triggered by the <primaryclientaction> for a table cell component which call into static java methods. But I haven't been able to figure out what binding to use to get at the Java instance for that cell's row in order to use <invoke> to get at non-static methods in the row's view object. The ${uix.current} binding is stale at that point.
Are the table row data bindings just gone after the table is rendered or is there some alternate notation that lets me get at them.
Thanks in advance.

the primaryclient action should pass the rowkey of the current row (${uix.current.rowKeyStr}) as a parameter. This way the server can find the corresponding row on the server in an event handler.

I want to publish my data using datasocket connection on the net and I want to use Front panel binding. Can I?

I want to publish my data on the net.
I want to use front panel binding and I do not want
to write the code. Can I do that. What should I modify
in my datasocket server manager. The other question is, When I open my VI, I want to open automatically my DataSocket Server. My english is bad. When I open the LabView I also want to open my DataSocket server. How can I do this?

To use datasockets to publish data to be accessed via the web, see the following document.
http://digital.ni.com/public.nsf/websearch/F58A6C2DAAADECB68625672400636145?OpenDocument
This document explains how you can create an interactive Web page with which users can view data from a remote acquisition application without the common problems of a client-server application. You use the Measurement Studio DataSocket control and Microsoft Visual Basic to create a software component that you can insert in a Web page. You then use that Web page to read, write, or share data with other applications across the Internet.
If you want to publish data but do not want to write any code, you should consider the web publishing tool available in Labview 6.1. This tool allows
you to create a webpage to be published from the the LabVIEW webserver on your machine. See the following link for more information on ways to easily publish to the web from LabVIEW.
http://zone.ni.com/devzone/conceptd.nsf/webmain/E4E311FA046EE24586256B1F0074F39D?opendocument
As for starting the datasocket server when you run your VI, you can use the 'System Exec' VI to run the application. The exe to start the server is located in the following directory:
C:\Program Files\National Instruments\DataSocket\cwdss.exe
I hope this is helpful.

Variable data binding in Excel

Hi guys,
how can I use data binding in Excel planning solutions? In WAD data binding works perfect getting values from a userexit variable to an input ready user variable.
How to do the same in Excel?
We have the problem that the values of our user exit variable may change between two executions of the planning sequence. Nevertheless the planning sequence works with cached values of the variable.
Regards
Stefan

Thanks for the advice, but it is not quite the thing I am looking for.
I would like to use the same planning sequence in different scenarios , so the filter of the seqence contains input ready variables, which are used without variable screen. In WAD I can use userxit variables as source for input ready variables. How to do the same in Excel? Especially variables with multi single values.
Regards STefan

MVC - Performance of data binding

Hi Gurus out there
I have a concern regarding performance of (dynamic) data binding if I have a lot of <i>textEdit</i> fields containing huge amount of data on a view page.
<u>Scenario</u>:
The view page contains buttons <b>[Add textEdit field]</b> and<b> [Save all entries]</b>. If you click the button <b>[Add textEdit field]</b> then a (new) <i>textEdit</i> will be generated and the model remembers the total number of <i>textEdit</i> fields that have been generated.
DATA: textedit_count TYPE i,
      o_textedit     TYPE REF TO cl_htmlb_textedit,
      tabix(6)       TYPE c,
      binding_code   TYPE string,
      binding_str    TYPE string.
textedit_count = o_model->get_section_count( ).
DO textedit_count TIMES.
* Create a unique ID for a textEdit field:
tabix = sy-index.
CONDESE tabix NO-GAPS.
* String for the data binding of internal table model->data_stream_tab:
CONCATENATE '//model/data_stream_tab['
              tabix
              '].data_string'
         INTO binding_str.
* Dynamic data binding:
CREATE OBJECT o_textedit.
CONCATENATE 'myTextEditID' tabix
         INTO o_textedit->id.
o_textedit->width = 650.
o_textedit->height = 225.
o_textedit->_text = binding_str.
binding_code = o_textedit->IF_BSP_BEE~RENDER_TO_STRING( page_context ).
<htmlb:label for = "<%= o_textedit->id %>"
            text = "<%= o_textedit->id %>"
          design = "EMPHASIZED" />
<%-- Binding of the attribute (internal table) '//model/data_stream_tab<i>.data_stream' --%>
<%= binding_code %>
ENDDO.
Obviously the <u>whole</u> contents of the <i>textEdit</i> fields in the coding above are <u>always</u> "moved" from the web browser to the server and vice versa when the button <b>[Add textEdit field]</b> is hit every time even though the content of some <i>textEdit</i> fields haven't changed.
Does anyone have a good solution/optimization for this problem? Any suggestion, comment and/or answer will be very appreciated.
Thanks
HW

Place this code above any textedit elements you have in your page:
<script type="text/javascript">
var myFields = new Array();
</script>
Then place this code after every textedit elements, this code will get run when the page is loaded in the browser, right after your element. You are saving the ID and the default value of your element to an array. For every further element, increase the array counter by 1!
<script type="text/javascript">
myFields[0] = new Object();
myFields[0]["id"] = 'myTextEdit1';
myFields[0]["default_value"] = document.getElementById(myFields[0]["id"]).value;
</script>
Finally, include this function in your page (does not have to be at the bottom, I just put it here chronologically):
<script type="text/javascript">
function compareFields() {
for (var i = 0; i < myFields.length; ++i) {
    if(myFields<i>["default_value"] == document.getElementById(myFields<i>["id"]).value) {
    // nothing has changed, set to ignore-value (any highly unlikely value, like ")?.("
    document.getElementById(myFields<i>["id"]).value = ')?.(';
    // check against this value in your setter method
    // if this is set, then do not user submitted value to update your model attribute value
    // maybe do some output for debug purposes
    // alert(document.getElementById(myFields<i>["id"]).value);
}</script>
Now add this attribute to your submit button:
onClientClick = "javascript:compareFields();"
This should do, test it out and let me know.

Date not being displayed in the custom format

Hi ,
I have a problem wherein i am unable to change the format of the date.
I need the date to be in the format 'January 10,2010.' however the date is being displayed as '1/10/10'. I have tried all options for the date formatting. I specified the custom format as 'MMMM D,YYYY' as mentioned in the SAP Library. I am trying to use the std custom options like YYYY-MM-DD, the date is not being dispalyed in the custom format provided by SAP either.
I have binded date from the context, used the Current Date field provided by SAP. Nothing works.
Its not working on the new form. However the old forms have the same kind of formatting and are being displayed as desired.
Please suggest as to what the issue could be.
Thanks,
Soumya.

Hi All,
Even I'm encountering the same issue. I'm trying to control the outputted date format programmatically.Please have a look.
data: v_int_date like sy-datum,
v_ext_date(10).
v_int_date = '20110201'
write v_int_date to v_ext_date MM/DD/YYYY.
Here I've tried to convert the date to external format using a fixed format(MM/DD/YYYY). But still it's getting outputted in the format DD/MM/YYYY only as that's the way its defined in the User Master!
Is there any solution for this? How can I 'override' defaults in the SAP User Master?
Thanks,
Mahesh
