Mapped Data Binding

I will like to consider XMLBeans for mapping XML instance, at run-time,
into class loading/object instances/my-precoded handlers.
Looking for the richest possible framewark to process SOAP/XML instances without
code pre-generation, just run-time loading/calling of custom code. Yes - the SOAP
body is 100% schema based.
In a sense - XML instance will act as Declarative flow control thru non-XMLBeans-codeGenerated
handlers - for a each SOAP request
Castor and Quick are sometimes positioned to have such "mapped" functionality.
I noticed XMLBeans roadmap to support Web Services and fully/timely support XMLSchema
now searching for support of run-time routing to non-generated XML handlers.

Thank you for your responses,
i resolved my problem on another way.
@Ayyapparaj: Yes i call the execute in the component controller, but the data loss based on another problem. I used the public component of the model DC in both view DCs and create a data binding between the interface of the model DC and the component controler of both view components. At runtime, two model objects will be instantiated. That means that the two components uses two differen model contents.
Now i build in the view DC only one component, so that i use only one model object and i'm able to display the model content in all views.
Thanks

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.

Unable to find information on WS data binding error on WLS 9.2.03 startup

Frustratingly, when I Google for "WS data binding error" I get 'old' links to BEA forum issues which may help but these are nowhere to be seen on the read-only copies now on Oracle forums here :- http://forums.oracle.com/forums/category.jspa?categoryID=202.

List View Bound to XML Map Data

HI Have a list view that is bound to xml mapped data. It seems that on connection refresh that new data is not being updated into the SWF. My Binding is directly onto the cell ranges that are mapped into excel, so on updates the size of the maped table changes/rewrites over the old data.
When I refresh I am not picking up the newest data in the list view. Any thoughts on this on how I can fix.
Regards,
Mark

Thank you Ganesh, but I am not on Enterprise edition. I am successfully bringing in live xml data, however mapping more than one Query result from one xml file is giving my project some problems. Refreshing a list View I think is causing this issue. From within my project in design view I can Refresh the data.
When I publish the file to html/SWF when I refresh other components are refreshing but the list view and one other is not refreshing.....

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.

Data Binding for Custom Controls?

Hello,
I'm a little bit confused of how to use databinding for custom controls.
I know i can bind a property, as seen here http://help.sap.com/saphelp_uiaddon10/helpdata/en/91/f0f3cd6f4d1014b6dd926db0e91070/content.htm, but how can I map whole arrays?
My problem is the following:
I want to create a custom table control in SAPUI5 (as the default one doesn't provide the neccessary options and properties I need), but I can't seem to find an example how to bind "rows".
There has to be a way to do this properly. All I can think of now, and implemented, is, passing the name of the variable in the model...
var x = new my.controls.complex.table({data: "/status"});
var row1 = new my.controls.complex.columnHeaderRow();
row1.addColumn(new my.controls.complex.column({text: "", rowspan: "2", colspan: "1", content: "FIRST_COL"}));
x.addColumnsRow(row1);
x.placeAt("content");
...my JSON/model looks like:
{ "status": [ {"FIRST_COL": "a" , ...}, {"FIRST_COL": "b", ... }, ... ], ... }
(which should translate into /status/0/FIRST_COL, /status/1/FIRST_COL, ... AFAIK)
... and then I use this variable name by getting the application-wide model and use the variable passed as key for the model... (please note, this code is just a snippet)
       var sapCore = sap.ui.getCore();
            if (sapCore !== undefined) {
             var model = sapCore.getModel().getObject();
             if (model === undefined || model == [] || model == null){ } else {
              $.each(model, function(idx, item){
               $.each(oControl.getColumnsRows(), function(idx, item2) {
                $.each(item2.getColumns(), function(idx, item3){
                 var content = item3.getContent();
                 if (content !== undefined && content != ""){
                  outpLine = outpLine + "<td>" + model[idx][content] + "</td>";
...which still leaves me with the problem of to get an event to react to re-render on changes within the data model, as well as when there would be just an control-specific model, or just a sub-node within a model etc.
So my question is:
Is there a way/best practice to define data binding in a custom control and have a way to react on it, and how to react on data changes within a custom control?
Thanks & KR
Chris

I create a entirely new control, from sap.ui.core.Control.
sap.ui.core.Control.extend("my.controls.complex.table",{... });
I did define a aggregation...
        aggregations : { columnsRows: {type : "my.controls.complex.columnRow", multiple : true, visibility: "public"}     },
...yet I'm still unclear how I work with this aggregation and databinding. I know we can use the bindAggreation functionallity, but since the aggregation is a object (my.control.complex.columnRow) I don't know how my JSON model should be able to bind to that aggregation (as well as how would one be able to cascade a aggregation like this down futher? For example if there is an aggregation in the object of my aggregation?), plus it still doesn't solve my problem of how I can react (for example redraw) on model changes.
Thanks in advance,
Chris

Best Practice: Data Binding

Each non-trivial Swing application needs to bind GUI elements (windows and components) to data. Ten years back in my MFC times, the typical solution was to initialize the GUI with fixed data, show the window, and read back the modified data after window closure. But in Swing, there is more flexibility (data can be dynamic for example). But what is the best way to deal with data binding?
- Writing custom models, bound directly to data objects?
- Initializing once and read back after window closure?
- Using the non-standard (but rather interesting) beans binding API?
Certainly there are more solutions, but my intention is not to write a list of possibilities or to get your opinion on one of these solutions. Actually I'd like to know from the experienced Swing pros in this forum, whether there is a best practice for data binding?

Hi,
I'd say it depends on what kind of data are you binding and if they're refreshed or not. In our "framework" we're using Properties-based approach for dialogs - server packs an @Entity into class similar to Properties - basically it's s Map<String, Object>, sends this Properties to client and values are put into our customised components. We're using component name as a key, most of controls are simple extends of standard JComponents with handful of methods from common interface (like load(), save(), ...). This approach seems to work fine.
For refreshed "lists" we're using again our custom "framework" based on sending initial batch and consequent diffs - there is sort of event queue responsible for telling everyone what had been changed. Because this kind of data tends to be quite huge, we're sending gzipped binary representation of source data.
With beans there might be a way how to implement both simply by calling getters, but then every single value results in one roundtrip, which was absolutely unacceptable for us. But I can imaging this working fine on LAN.

Pageflow - data binding for collection size

Assume {pageFlow.students} is a collection. What data binding to use to write the
collection size to the jsp page? The following does not work
<netui:label value="{pageFlow.headers.size}" />
Thanks, Jack

This is a very FAQ on the "taglibs-user" mailing list. The same issue comes up
with using the JSTL, because the JSTL follows the same rules about what it can
access.
A reasonable general solution would be to write a simple class called "CollectionBean"
(and similarly "MapBean"). Put it in a "utils" package. It's constructor takes
a Collection (and a Map, respectively). It has two properties, named "collection"
and "size" (the other would be "map" and "size"). Instead of storing Collections
or Maps, you store CollectionBeans and MapBeans. About the only challenge would
be properly naming the instance variables of type CollectionBean, so it isn't
confusing. I'll leave that problem for you.

Hello,
I've never seen those errors before, but I would guess that you are missing some library modules from your web-app's WEB-INF/weblogic.xml or ear's APP-INF/weblogic-application.xml. Are you seeing these errors on the producer or the consumer?

Building my own data-binding method

Hi,
After looking at the various packages that allow you to do data-binding I have decided for my case it's just simpler (number of lines) to do something myself.
If I have an XML that has fields a through f, which correspond to A through F in MySQL fields. What's the best way to connect these two?
What's the best type to build this thing in? Maps, HashMaps, or Collections? I just don't know the advantages/disadvantages to each obviously.
Thanks.

My question wasn't clear.
For example if you have a customer entity and has one telephone number and now the users want it to have two telephone numbers then you must add a column to the database. And if you do a B2B xml with that data then you must upgrade the XML to add that new field.
That process is replicated in about 99.9% of all business processing and most of that does not need a runtime solution to the problem.
So the question becomes
1. How often do the requests arrive?
2. What is the nature of the request - how complex is it?"We would like to have dataPoint123 added to the excel file that we get every day" sort of thing, so we have to check to see if we have the data stored in the database, if not than we have to go back to the appliance and add it to the XML report that is generated. Than add it to the database to be stored. Modify the import of the XML code. Add in the data processing portion of the code if need be, add it to the export report.
If you are doing 50 of these a day and they are all simple then your design if flawed because you cannot continue to add that many columns to existing tables. This is further complicated if you are differentiating it by user (some users have different fields from others.) Again it would still represent a design flaw.It's more like 1 every two to three weeks. And since we don't touch the code every day it becomes a pain when something like this has to change, because we have to go find it in the 17 different places it needs to be touched.
The phrase "17 places" suggests a disconnect with what you described above. With "17 places" you have at a moderately complex change request.
And your description above doesn't sound like something that you can pattern.
If I have a database with tables/columns and the users request a change to a report frequently which originates with existing data then automating the report creation might be a worthwhile project. Myself with the given timeline I would opt for code generation rather than a runtime solution.
However if the data doesn't exist then you MUST rollout a code change. The DDL must change, you must have code to populate it, and perhaps other business rules are added. And that is unlikely to be something that can be patterned. Actually only way that could be patterned would be in a flow through system (source in => database => report)
>>
If on the other hand you get one of these every 6 months then you do not need a dynamic solution (at all.)I don't agree with the statement, I think "dynamic" nature of code is even more important with code that you don't touch/live with every day. I have C code that I live with every day, it's always been improved and worked on, I rarely do anything majorly dynamic in there, because I don't need it. It's faster than I need it to be, the foot print is small comparatively and it is changes too often to try to modularize it.
That paragraph seems contradictory. Or maybe it is a terminology issue.
"Dynamic" for this discussion relates to code generation, generalization (adding complexity in tradeoff for power), metadata type solutions, etc.
That said maintenance is the highest cost in software development. To maintain code someone must understand it. Adding a "dynamic" solution (above definition) into code means that it will take longer to find and fix bugs. And without rigorous process control over time it is likely to lead to more 'hacks' because someone couldn't figure out the correct way to fix something or because the existing design didn't allow for it and they didn't refactor.
Thus one must consider the tradeoffs carefully.
Note that with code generation one can achieve simplicity with ease of use. I do this commonly because I do not want to require other developers to understand the code creation process. So I create code generation tools to ease my work but check in the generated code so that if some other developer needs to maintain it they can work with that. I check in the tools to but at the point where they start maintaining the code it is their choice which route to use.

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 .

You should assign only one value to jdbc_sid. Try with this
<map_data_source name="mvdemo"
jdbc_host="localhost"
jdbc_sid="orcl"
jdbc_port="1521"
jdbc_user="mvdemo"
