Data binding in bsp

hi sdns,
how data binding is done in BSPS?
What is the diffference between DO_HANDLEDATA and DO_HANDLE EVENT?
What is the process flow when using mvc in BSPs?
Advance Thanks ,
chandana

Hi chandana,
1) how data binding is done in BSPS?
A) Databinding useful to have perfect interactions between view and model.
      Whenever user interacts with view, automatically the data which is entered by the user will be passed
     to the model using databinding.
     Declare reference variable for model class as page attribute in BSP.
     Sample code of BSP:
           <htmlb:inputField       id          = "f1" value = "//model/v1" />
           <htmlb:inputField     id          = "f2" value = "//model/v2" />
     Here i declared model as reference variable ,v1 and v2 are model class attributes.
     so automatically values of both input fields are passed to the model class attributes (v1 and v2).
2) What is the diffference between DO_HANDLEDATA and DO_HANDLE EVENT?
A) DO_HANDLEDATA is used to handle the data. As data binding is available, we don't need to use this
     method.
    DO_HANDLE EVENT is used to process the actions performed in the view.
3) What is the process flow when using mvc in BSPs?
A) MVC flow doesn't change in bsp.As we know in MVC , whenever user trigger action in the view,
       Controller process the action and determine what should be happened next such as calling model
       class and displays next view in the process flow.The same flow occurs in BSP .
Hope it helps.

Data Binding in BSP - tableview entry not getting deleted.

Dear Gurus,
I am very new to the BSP concept.I am told to develop a BSP for creating,updating,deleting entries from a database.I have achieved create and update,But when i am deleting,it gets deleted in backend i.e. in the SAP database,But the entry still appears there in the Front end.And the other 2 events i dont think i have handled well , as all i am doing is, I am appending or modifying the entries in the form_fields and then calling the do_handle_data event.
Please help me out in how to handle the table view events,I have heard about the selectedrowindex,but i couldnt figure that out.
Kindly help me out.
Helpful answers would definitely be rewarded.
Cheers,
Deepthee Kasal

Thanks Beth for your insight,
The info requested are:
UWLJWF version: 7.00 SP22
Neither the Manager nor the Substitute's IDs are deleted. They are both active.
Just that the Substitute has moved to another Org unit.
Another information is that, the HR Personnel's here have a Custom program, which would get the Substitute assignments in the Backend - Which also gives the feature of deleting the substitution.
I suspect that, this particular substitution might have got deleted in the Backend with this Custom Program (TCODE).
Regardless of this, it seems now that there is inconsistency between backend & portal.
At this circumstance, is there a way to clear this issue?

Regarding Model Data Binding.

Hi Jain,
Data binding enables data transfer between views and models, so that we don't have to add or change controller coding to work with models.
Syntax for DataBinding:
For <htmlb:InputField>
<htmlb:InputField value="//query/a"/>
This example code creates an inputfield that takes its initial value from the a attribute of query model.
here query is the instance for model we can define in conroller Do init method.
For ex if you want to add two numbers by using model data binding.
Create method add in model which has three attributes value1,value2, and result.We have to define these attributes in model.Result is to print the added vaue.
Then we have to add these values to the model in the view by using above syntax:
<htmlb:InputField value="//query/value1"/>
<htmlb:InputField value="//query/value2"/>
<htmlb:InputField value="//query/result"/>
here query is instance for the model.
Here you have to remeber one point that no need to define these attributes(value1,value2,result) in the view again but you have define model instance in the attributes of view.
Try using this concept..........
Reward points if useful.

Hi Anubhav,
                Model Data Binding in business server pages ensure that data which is entered by the user in
                the user interface(view) automatically passes to the model attributes and also output from the
                backend system automatically passes to the result view.
                So we need n't handle the data which is going to backend or the data which is coming from
                backend system.
                Data binding takes care of all the data handling .so we need n't write code to handle the data.
                All i can say is data binding means binding the UI elements with the model class attributes.
               If data binding is not available in BSP, we would have written lot of code in controller class
               of business server pages.
              I am giving simple example here to make you understand.
               The initial view in this application contains 2 input fields, 4 radio buttons and 1 button.
               Here radio buttons named Add, Multiple , Subtract and Divide.
               The functionality i this application is whenever user enters numbers in input fields and select on
               radio button and click on button , the result has to be displayed in the result view.
              Initial View:
<htmlb:content design="design2003">
<htmlb:page title = " ">
    <htmlb:form>
<htmlb:textView     text            = "value1"
                          design        = "EMPHASIZED" />
    <htmlb:inputField       id          = "f1" value = "//model/v1" />
     <htmlb:textView     text          = "value2"
                          design        = "EMPHASIZED" />
        <htmlb:inputField     id          = "f2" value = "//model/v2" />
     <htmlb:radioButtonGroup id="rbg" selection="//model/s" >
        <htmlb:radioButton id="id_add" text="add"/>
        <htmlb:radioButton id="id_sub" text="sub"/>
        <htmlb:radioButton id="id_mul" text="mul"/>
        <htmlb:radioButton id="id_div" text="div"/>
      </htmlb:radioButtonGroup>
</htmlb:form>
This code in the above view shows the data binding;
<htmlb:inputField       id          = "f1" value = "//model/v1" /> and
<htmlb:inputField     id          = "f2" value = "//model/v2" /> and
<htmlb:radioButtonGroup id="rbg" selection="//model/s" >
Here v1,v2 and s are model class attributes . model is reference variable of model class .model is declared
as page attribute in BSP.
As i said above automatically the values of inputfields are passes to the model class without writing the code.
   Code in model class method:
METHOD toall.
IF s = 'id_add' .
    v3 = v1 + v2.
ELSEIF s = 'id_sub'.
    v3 = v1 - v2.
ELSEIF s = 'id_mul'.
    v3 = v1 * v2.
ELSE.
    v3 = v1 / v2.
ENDIF.
ENDMETHOD.
</htmlb:page>
</htmlb:content>
   Result View:
<htmlb:content design="design2003">
<htmlb:page title = " ">
    <htmlb:form>
      <htmlb:textView     text          = "output"
                          design        = "EMPHASIZED" />
      <htmlb:textView     text          = "//model/v3"
                          design        = "EMPHASIZED" />
    </htmlb:form>
</htmlb:page>
</htmlb:content>
       Here the result is available v3 attribute of model class and it is binded to the text view of the result view.
      Finally the result is displayed in result view.In the above example i didn't explain about controller class
      I hope you know about controller class.
      Hope it helps.

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.

Report data binding error

I have created a banded report split into departments. Each
recore has a value associated with it. The report runs fine if I
dont try to sub-total each departments vale, but if I add a
calculated field to the banding, I get the following error:
Report data binding error Error evaluating expression :
textField_2 Source text : calc.Department_Total.
Variable calc.Department_Total is undefined.
The calculated field is simply the sum of the values, with an
initial value of 0 and set to reset when the group changes on the
department. I am using the same data type for the calc field as it
automatically gave for the original Value field (Big Decimal)
Any ideas?
Dave H

Does anyone have any ideas about this, Its getting a bit
critical now. Has anyone else been able to do sums that calculate
on group changes?? The sum total works for the report, jusyt not
the bands. I desparate here, pulling my hair out.

Dynamic Data Binding at runtime

For future applications, flexibility will be an important feature. One of the biggest drawbacks of forms is/was, on my opinion, not being able to create new items at runtime.
JClient will easily overcome this restriction. But how about data binding ?
Imagine the following situation: We've got a VO "order" with the "custname" incorporated as lookup data. At runtime, the user decides that she needs to see the "custloc" as well (put an additional JTextField into some whitespace on his panel). As I understand it is possible to build a view link to tie an instance of the VO "customer" to the "order" (I'd prefer that over adapting the query statement of "order" at runtime). But how can I create the new iterator binding and control binding needed to populate the dynamically created attributes with the data from "customer"? And, further on, how will I be able to make the changed configuration of my panel persistent, let's say into the DB ? Or does the data binding concept of 10g just not cover this requirement?

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 .

Passing data from one bsp application to another

Hi,
I have few queries that most of you would have done in ur projects:
1. I want to pass data from one bsp application to another:
eg based upon selected row of table view which populates material no and descriprion to another application which open the entire material master data.
Now, i have both the pages in diff bsp applications in place but unable to pass the selected material code to the second bsp application.
Had it been two different pages of same application I was able to achieve it with set parameter()
2. To stop the application from reprcessing the data:
eg: Suppose I have a bsp page where user fill details of a customer and on submitinng the details a customer is created in background and the entire page is disabled by my code. Even now if the user press refresh (F5) button then another customer gets created in the background. So basically i want to avoid the reprocess of the onSubmit event
Few lines of sample code would be very helpful.

Context Mapping and data binding

Hi,
Please explain about the context mapping and data dinding
and also differences
Thank's & Regard's.
Sri

Hi Sridevi Sudunaguntla ,
context mapping-> means mapping between different contexts
ie suppose if we are creating a node in the component controllet and if we want to use that node in view a and view b, then we have to map this node from component controller to the required view.. this mapping of context nodes is called context mapping..for context mapping, create nodes in compcontroller.. tehn go to view-> context-> tehn drag and drop required node from component controller to the view ..
data binding-> means binding the data from nopde to the ui elements or viceversa... after the nodes are created in indudual views or after context mapping.. we have to bind these nodes to the ui elements... suppose we have an input field and we want to read that,, so we have to bind the input field to an attribute in the node.. this binding is called.. data binding.

Report data binding error unknown column name

Hi,
I am having a problem with the new 7.02 update of Report

I did manage to fix one of my reports by using the basic mode
and selecting all my tables and seting my linkage and criteria.
I have other computers that i have not updated to 7.02 and
they do not have this issue. Below is the error:

Anyone have any Ideas??

Thank you very much for help.
The "Unknown column name " is a field still used in my
report, so I can't remove it.
After I clear the query in the report and reopen the report
and apply the same query back to it, I get different error message:
Element TASKNUM is undefined in QUERY.
The error occurred in : line 1
-1 : Unable to display error's location in a CFML template.
I know for sure this "Element TASKNUM is undefined in QUERY."
is defined in query. each time it complains something different. I
get really confused.
Thanks again.

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.)

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.

Report data binding error with date values

I have CF7.02 with a Microsoft Visual FoxPro 9.0 SP1 Database
that I connect to using ODBC (FoxPro Driver 6.01.8630.01). I send
my sql results to a CF Report Builder 7.02 PDF report and it works
fine. If I dump the date values before I change them, they look
like the following: {ts '2004-12-20 00:00:00'} . However I have
tried a number of ways of manipulating the date before sending it
to the report, but I continue to get errors. I don't care what
format they go to the report in, since the report reformats them
anyway. I checked to make sure that none of the dates were null.
For example <cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDateTime(#ldCFPrcInputDate#) /> yields values in the
{ts '2004-12-20 00:00:00'} format when I dump the query results to
screen. Where:
ldCFPrcInputDate = 12/20/2004
CreateODBCDateTime(ldCFPrcInputDate) = {ts '2004-12-20
00:00:00'}
ReportQuery.PrcInputDate[lcCurRow] = {ts '2004-12-20
00:00:00'}
I get the error:
Report data binding error Unable to get value for field
'prcinputdate' of class 'java.util.Date'.
coldfusion.runtime.OleDateTime -> Date
Not using the CreateODBCDate function for example <cfset
ReportQuery.PrcInputDate[lcCurRow] = #ldCFPrcInputDate# /> I
get:
Report data binding error Unable to get value for field
'prcinputdate' of class 'java.util.Date'.
java.lang.String -> Date
Here are some of my failed attempts:
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDateTime(#ldCFPrcInputDate#) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
#ldCFPrcInputDate# />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
DateFormat(CreateODBCDate(#ldCFPrcInputDate#),'mm/dd/yyyy') />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate(DateFormat(#ldCFPrcInputDate#,'mm/dd/yyyy') />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate(DateFormat(#ldCFPrcInputDate#,'mm-dd-yyyy') />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
Trim(createODBCDateTime(ldtmpdate)) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate({05-07-2006}) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate('{05-07-2006}') />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate(05/07/2006) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate('05/07/2006')/>
<cfset ReportQuery.PrcInputDate[lcCurRow] =
CreateODBCDate(parseDateTime('05/07/2006')) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
parseDateTime(CreateODBCDateTime(05/07/2006)) />
<cfset ReportQuery.PrcInputDate[lcCurRow] =
parseDateTime(CreateODBCDateTime('#ldCFPrcInputDate#')) />
<cfset ReportQuery.PrcInputDate[lcCurRow] = '{05-07-2006}'
/>
<cfset ReportQuery.PrcInputDate[lcCurRow] = '{05/07/2006}'
/>
<cfset ReportQuery.PrcInputDate[lcCurRow] = '05/07/2006'
/>
I also did some googling without success. Any help is
appreciated.

You may want to make sure that the column is not included in
the query variable list in your report cfr file.
The newest version of the Report Builder, which may be
installed on the server, no longer tolerates vars appearing in that
list of they are not in the query itselft.

User Report data bind variable problems

Hello,
I am trying to build a simple report in SQLDeveloper, using a DATE bind variable. But it fails with the error message:
Inconsistent datatype, expected DATE got NUMBER
SELECT * FROM FLOW_COMP_REC_SUMMARY_RU
where create_date = trunc(:TARGET_DATE)
and type = 'D'
ORDER BY MESSAGE_FLOW_ID
Running this query in SQLDeveloper worksheet executes properly after a dialog box pops up and I enter: current_date - 1
SELECT * FROM FLOW_COMP_REC_SUMMARY_RU
where create_date = trunc(&TARGET_DATE)
and type = 'D'
ORDER BY MESSAGE_FLOW_ID
I've searched but no clear solutions present themselves. If you have one it would be most appreciated.
Thanks

You'll have to convert the input to date yourself:
SELECT * FROM FLOW_COMP_REC_SUMMARY_RU
where create_date = TO_DATE(:TARGET_DATE, 'DD/MM/YYYY')
and type = 'D'
ORDER BY MESSAGE_FLOW_ID
Have fun,
K.

Shared variable vs. data binding

Hi,
I try to write a program which communicates motor drives through ethernet and I use OPC server and shared variables created using PLC. I created front panel indicators in a while loop with 50 ms cycle to read motor encoder position, status etc. When I try to do this with wiring shared variable to indicator and with changing the data binding property of the indicator browsing the same variable from the project library, data binding seems to respond slower than wiring the shared variable to indicator directly. Can anyone explain why?

Hi mhn05,
I'm not exactly sure why it would be operating slower. Do you have code that you can upload that benchmarks or tests the speed of these, side by side?
Thanks,
