Dynamic create of attributes

Hello friends Can I create the attributes Dymanically and assign Values to it.

Not sure whether you have seen this document earlier..
If not look at this document & from page number 31 for dynamic field creation & binding.

How to set a value to a dynamically created node/attribute?

Hi,
I dynamically created attributes using the following method,
IWDNodeInfo cbOptions = wdContext.getNodeInfo().addChild("cbOpt"+count, null, true, true, false, false, false, true, null, null, null);
cbOptions.addAttribute("opt"+critEle.getQuest_Critid(), "ddic:com.sap.dictionary.string");
How do i assign a value to it now, since the node/attribute cannot be accessed via wdcontext?
On a side note, it seems really troublesome if i need to use a checkbox grp(s) dynamically. I actually need to dynamically create a seperate node + attribute for each checkbox grp i have. Is there any better way to do this?
Thanx in advance

Hi
Steps:
1) Create the action click is done statically (you cannot create action dyanmically)
2) binding the action click to checkbox dynamically
code
public static void wdDoModifyView(IPrivateDynamicProgrammingView wdThis, IPrivateDynamicProgrammingView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
    //@@begin wdDoModifyView
     if(firstTime){
                  IWDTransparentContainer con=(IWDTransparentContainer)view.getElement("RootUIElementContainer");
          IWDCheckBox checkBox=(IWDCheckBox)view.createElement(IWDCheckBox.class,"ck");
          IWDAction act=wdThis.wdCreateAction(IPrivateDynamicProgrammingView.WDActionEventHandler.CLICK,"");
          checkBox.setOnToggle(act);
          con.addChild(checkBox);
    //@@end
Thanks and Regards,

Dynamically created "alt" attribute not displaying

Hi, I have created a details page for our company product, which is diplayed dynamically. I have on this page a dynamic image as well thats pulled from my database. As with any image on the web, I want to set the alt attribute, but of course this has to be dynamic as well. I have done this it seems, as I view my source code from a browser, I can see that the alt has a value there and that it is the correct value. My question is, why doesnt this display when I mouse over the image? Is there something I am forgetting to add? Is this attribute deprecated? here is my code for the alt cfoutput:
function(){return A.apply(null,[this].concat($A(arguments)))}
<cfoutput>
 <table align="center">
 <tr>
 <td><cfif rsDetails.image1 NEQ "">
 <a href="images/#rsDetails.image1#" target="_blank"><img src="images/#rsDetails.image1#" alt="#rsDetails.item#" /></a>
 </cfif></td>
 </tr>
 </table>
 </cfoutput>
Here is the source code from the browser that shows there is an alt value:
function(){return A.apply(null,[this].concat($A(arguments)))}
<table align="center">
 <tr>
 <td>
 <a href="images/60K19DL.jpg" target="_blank"><img src="images/60K19DL.jpg" alt="60K19/DL" /></a>
 </td>
 </tr>
</table>
I hope this is easy to understand without going into lengthy detail. Thanks for any help!

Ok I understand what you're saying now. lol I did try my code without the <a> tag but still didn't work. SO thats kinda weird.
However, until you pointed it out, I didn't realize his site didn't have the mouse tips in firefox or that other browsers didn't support it, so I guess its not that important after all...the tips I mean.
I hate IE too! but unfortunately when dealing with an online wholesale site, I must use and develop for IE.
Anyway, thanks for the help! I may try the title attribute, but I think as long as I have the alt for SEO then I am fine.

Adding f:Attribute dynamically to a dynamically created Button

Hi ,
I am trying to dynamically create a CommandButton and attach a f:Attribute to the same. But somehow I am not able to get hold of the correct API to do the same -
>RichCommandButton button=new RichCommandButton();
>button.setText("Ok");
>AttributeTag attr=new AttributeTag();
>attr.setValue("DC_OPERATION_BINDING", "bindings.DENY");
>button.getChildren().add(attr);
The issue is that the add method expects a UIComponent and attr is of type com.sun.faces.taglib.jsf_core.AttributeTag

gues u can use it like
button.getAttributes().put(DC_OPERATION_BINDING", "bindings.DENY");
{code}

Attribute Binding dynamically created fails validation

Hello.
In my taskflow I need to create both an Attribute Binding and a UIComponent (RichInputText), this is the code:
DCBindingContainer dcBindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding it = ADFUtils.findIterator("MyViewIterator");
JUCtrlAttrsBinding nb = JUCtrlAttrsBinding.createAttributeBinding((JUFormBinding)dcBindings,null, "MyView", null, "MyViewIterator", "MyNewField");
dcBindings.addControlBinding("MyNewField", nb);
Then I create the RichInputText in a PanelFormLayout with his validator:
*ValidatorTag.BindingValidator vb = new ValidatorTag.BindingValidator(null,JSFUtils.getValueExpression("#{bindings.MyNewField.validator}"));*
*((UIXEditableValue)newRichInputText).addValidator(vb);*
The problem is on the validator.
I see the new InputText in my page and the value is right, but when I submit the field I see this error:
"Unable to resolve a Validator instance using either validatorId '' or binding '#{bindings.MyNewField.validator}'."
If I create the Attribute Binding at design time (in my PageDef) and I create dynamically the UIComponent with the validator, there is no problem!!!
Why with the dynamic creation of the Attribute Binding, the validator doesn't works (the others bindings properties work perfectly) ?

Use
Checkbox.bindChecked("<<ValueAttributeName>>);
or
Checkbox.bindChecked("<<.ValueNode.ValueAttributeName>>);
if the the attribute is inside a valuenode.

How to add a table (dynamic created) into a model attribute

i have dynamically created an internal table. Generally i use model-binding in a stateful MVC-Application.
Is there a possibiltity to transfer the dynamic table to a model. As far as i know generic attributes are not allowed in the modell class.
Every hint welcome
thx in advance

By some miracle I do have this finally working. I will warn you up front that the code is not the cleanest (I have stuff copied in from all over the place. I probably have lots of unused variable references - but I am running out of time to clean it up further). Also I don't have all the logic to support all your different possible dynamic structure types. I always use SFLIGHT as my dyanmic structure. Therefore you will have to adapt the coding to lookup the actual structure type in use.
So I have a model that has an structure ITAB type ref to data. In my Model initialization I go ahead and dynamically redfine this to my specific type:
METHOD init.
SELECT SINGLE * FROM sflight INTO CORRESPONDING FIELDS OF isflight.
DATA: struct_type TYPE REF TO cl_abap_structdescr,
 tabletype TYPE REF TO cl_abap_tabledescr.
struct_type ?= cl_abap_structdescr=>describe_by_name( 'SFLIGHT' ).
CREATE DATA me->itab TYPE HANDLE struct_type.
ENDMETHOD.
Then in my View I have the following:
<%@page language="abap" %>
<%@extension name="htmlb" prefix="htmlb" %>
<%@extension name="phtmlb" prefix="phtmlb" %>
<%@extension name="bsp" prefix="bsp" %>
<htmlb:content design="design2003" >
<htmlb:page title=" " >
 <htmlb:form>
 <phtmlb:matrix width="100%" >
 <%
field-symbols: <wa> type any.
assign model->itab->* to <wa>.
* append initial line to <wa_itab> assigning <Wa>.
data: descriptor type ref to CL_ABAP_STRUCTDESCR.
descriptor ?= CL_ABAP_STRUCTDESCR=>describe_by_data( <wa> ).
data: flddescr type DDFIELDS.
flddescr = descriptor->GET_DDIC_FIELD_LIST( ).
field-symbols: <wa_field> like line of flddescr.
data: label type ref to cl_htmlb_label.
data: input type ref to CL_HTMLB_INPUTFIELD.
data: binding_string type string.
"Loop through each field in the structure Definition
loop at flddescr assigning <Wa_field>.
clear label.
clear input.
concatenate '//model/itab.'
<wa_field>-FIELDNAME
into binding_string.
label ?= cl_htmlb_label=>factory( _for = binding_string ).
input ?= cl_htmlb_inputfield=>factory( _value = binding_string ).
 %>
 <phtmlb:matrixCell row = "+1"
 vAlign = "TOP" />
 <bsp:bee bee="<%= label %>" />
 <phtmlb:matrixCell col = "+1"
 vAlign = "TOP" />
 <bsp:bee bee="<%= input %>" />
 <%
endloop.
 %>
 </phtmlb:matrix>
 <htmlb:button id="Test" onClick="Test" text="Submit"/>
 </htmlb:form>
</htmlb:page>
The key to making this work are custom getter/setters. In your model class, you can copy from the template methods (Like GETM_S_XYZ for the metadata structure method). Copy them and remove the _ on the front of the name. Then change XYZ to the name of the attribute you are binding for. The following are my custom methods.

I know that is a LOT of nasty code without too much explanation. I'm afriad there isn't time right now to expand on how it works too much. Between my day job and trying to finish the BSP book, there just isn't much time left. Like I said before there is a very large section in the book on this topic that hopefully explains it. The book will be out in December or early January - but perhaps I will get some time before then to write up something on SDN about this.

Dynamically create document type Item Attribute using WF_ENGINE.AddItem API

Hi
Is WF_ENGINE.AddItem API , supported to create document type Item attributes dynamically ? If yes how do we set the display name of the attribute. If no then is there is any other method to dynamically create document tyoe item attribute?
Thanks

Hi,
If the document is stored on a file system, then I would replace the message body with a PL/SQL document which includes links to the files as straightforward URLs. There would be no need to include them in the Workflow in any way. For example, I recently worked with a client where all the (file) attachments made within eBusiness Suite were then migrated into Oracle Universal Content Management and the attachment was replaced with a URL to the new document. Any notifications now just reference the URL link to the document within the document management system in an HTML notification. While the processing is going on, the user is given the list of files that exist as attachments, but no links because the document is being processed by the management system.
If the attachments are going to be stored in Workflow as documents, you won't be able to change the display name though - display name is set for the attribute on the message, not for each specific notification. Changing the value of the display name for the message would impact all notifications that use that message, which isn't what you want.
What you need is to dynamically build the notification (either using PL/SQL or OA Framework) and include a list of attachments in the notification. This may be a direct link to the document (either in a document management system or on a file system somewhere) that you can render as a URL, or a link to code that can retrieve the document from the database and serve that to the user. This is not a straightforward piece of work.
If this is purely internal, you might be better off having a custom form / screen which displays the different documents, and link to that from the notification. Or you could link to a standard form for the transaction and have the users pick up the attachments directly from the transaction.
HTH,
Matt

How to access a dynamic created attribute in a context node?

Hello,
who could help? I can't set a value for a dynamically created attribute which is bind to a table.
My context of the view looks as follow (is defined in NetWeaver):
- Context
 - Availability (Node)
 - vctxService (Attribute)
 - vctxServiceDesc (Attribute)
 - ... (further predefined attributes)
 - ... (some have to be set dynamically as follows)
Then I have added attributes dynamically in the wdDoModifyView(...) - method, as follows:
for (int i = 0; i < max; i++) {
 // some code to dynamically create table columns
 // adding attributes dynamically
 IWDAttributeInfo attrInfo = wdContext.nodeAvailability().getNodeInfo(). addAttribute("vctxAvailability_" + i, "ddic:com.sap.dictionary.string");
 tv.bindText(attrInfo); // bind to TextView in table
In the method onPlugFrom... I tried to set the values for the attributes "vctxAvailability_ + i" as follows:
for (int i = 0; i < max; i++) {
 IAvailabilityElement newAvailNodeElement = wdContext.createAvailabilityElement();
 // some values will be set for the
 // predefined attributes of AvailabilityNode
 // newAvailNodeElement.set...( value );
 // newAvailNodeElement.setVctxService( xy.getServ() );
 // now the values of dynamically created and added
 // attributes in AvailabilityNode will be added
 // THIS DOESN'T WORK
 newAvailNodeElement.setAttributeValue ("vctxAvailability_" + i, "value" + i);
It would be great if someone could help me.
Thanks in advance.
Kind regards,
Carsten

Carsten,
Here is a sample code that creates context attributes dynamically and also sets values:
//Creates a node
IWDNodeInfo nodeInfo = wdContext.wdGetAPI().getRootNodeInfo().addChild("TestNode", null, true, true, false, true, false, true, null, null, null);
//If you want to bind the node to a model node then the
//second argument to the above method should be the
//model class.
//Creates an attribute under the node just created.
IWDAttributeInfo testAttrib = wdContext.wdGetAPI().getRootNodeInfo().getChild("TestNode").addAttribute("testAttrib", "ddic:com.sap.dictionary.string");
IWDNodeElement testNode = wdContext.getChildNode("TestNode", IWDNode.LEAD_SELECTION).getCurrentElement();
IWDNode testNode2 = wdContext.getChildNode("TestNode", IWDNode.LEAD_SELECTION);
//Now you can bind testNode with the Model Node
//You can also set a value to the newly created attribute
testNode.setAttributeValue("testAttrib", new String("Value"));
Hope this helps.

Modify dynamically created attributes.

Hi,
I have created dynamically many check boxes based on a sql query result.
I have created also a dynamic node with many attributes to make the binding to my check_boxes.
I want know to acces my check_boxes to perform action : check, uncheck ...
how can i proceed?
Thanks.

Hi ,
try getting the IF_WD_CONTEXT_NODE_INFO instance for the node.
DATA : lo_node_info TYPE REF TO IF_WD_CONTEXT_NODE_INFO.
my_node->GET_NODE_INFO().
IF_WD_CONTEXT_NODE_INFO has a method GET_ATTRIBUTES().
Which returns a table of type WDR_CONTEXT_ATTR_INFO_MAP.
The line type of this table is WDR_CONTEXT_ATTRIBUTE_INFO.
This structure has fields like name and all the properties of the attribute.
Check if this method could help you out.
Although I cannot guarantee if this method works for dynamic nodes and attributes.
But worth a try.
Thanks,
Aditya.

ABAP OBJECTS: Dynamic Create object

Hi folks!
I have a problem... I need to create a dynamic type object with:
DATA: my_instance TYPE REF TO class1.
CREATE OBJECT my_instance TYPE (class2).
* where class1 is a superclass of class2.
When I do:
my_instance ?= m_parent.
* where m_parent is an instance of class1
My problem is when I want to access to an attribute of the class2, the compiler says that it cannot find the attribute (this is OK, because the attribute is only in the class2).
My question:
Is there anyway to access to an atribute of second class when is not in the first class? (i don't want to create the attribute as an attribute of the first class).
Thanx!!!!

Hi David,
When you do the debugging, you are dealing with run-time - i.e., the program is now running and you are just interrupting it at each statement to examine the program state. You will reach the point where the object is already created. That is why you can see all those attributes. But when you comiple, the program is not yet running, so the attributes will be unknown because of the dynamic type specification.
I think you will have to redesign the program logic. As i had already said in my earlier post, it is not proper to have the attributes specified statically while the class itself is specified dynamically.
Your situation is somewhat similar to -
DATA ITAB TYPE TABLE OF SPFLI.
PERFORM TEST TABLES ITAB.
FORM TEST TABLES ITAB.
LOOP AT ITAB.
WRITE: / ITAB-CARRID.
ENDLOOP.
ENDFORM.
Hope the point is clear.

Anand Mandalika.

Adding AJAX support for dynamically created panelGrid components

How get context value form a dynamic created node

Hi all,
I have build my own dynamic view. In this view I use also a dynamic created Node. When I have more rows in my Node I see every row with context of the last row of the dynamic Node.
this is the source I use.
for (int x = 0; x < dynTabNode.size(); x++)
dynTabNode.setLeadSelection(x);

How can I read my Node row for row?

The reason is that all these Caption UI elements are bound against the same context attribute. At runtime this will be resolved to the attribute value of the lead-selected node element. In this example you can fix this by not binding the "text" property but setting it to the attribute value of the iterated node element:
for (int x = 0; x < dynTabNode.size(); x++)
dynTabNode.setLeadSelection(x);
IWDGroup group = (IWDGroup)view.getElement("Group_name");
IWDCaption name = (IWDCaption) view.createElement(IWDCaption.class, null);
IWDNode dayNode = wdContext.getChildNode("DayNode", IWDNode.LEAD_SELECTION);
String text = (String) dayNode.getElementAt(x).getAttributeValue("Name");
name.setText(text);
IWDAttributeInfo aiName = dayNode.getNodeInfo().getAttribute("Name");
name.bindText(aiName);
group.addChild(name);
(I assume here that the node "DayNode" has the same size as dynTabNode. No idea if this assumption is correct)
But this would not help for editable elements where you need to bind the edited property.

Dynamic creating SAPBobsCOM objects using reflection

Hi All,
I'm writing a tool (C#) for SBO for exporting object (oItems, oBanks etc.) to XML files. And I have a problem how to dynamically create object by it's string description. I'm trying to create it using System.Reflection, but cant't find right way to create it.
It must be like that, but it doesn't work:
           Type sboObject = System.Type.GetType("SAPbobsCOM.Items, Interop.SAPbobsCOM", true, true);
           object ibaseObject = Activator.CreateInstance(sboObject);
Any ideas?)

Hi
I've writen this code for instantiating DI API objects using .NET reflection
        private object getObjectBo(int tipo) //tipo: integer representing the object type
            object o = null;
            try
                Type tipoComp = kernel.Company.GetType(); //Type SAPbobsCOM.Company
                MethodInfo info = tipoComp.GetMethod("GetBusinessObject");
                object[] parametros = new object[1]; //Parameters of GetBusinessObject
                object tipoObj = Enum.ToObject(typeof(SAPbobsCOM.BoObjectTypes), tipo);
                parametros[0] = tipoObj;
                o = info.Invoke(kernel.Company, parametros); //Calling GetBusinessObject
            catch (Exception ex)
                kernel.Application.MessageBox(ex.Message, 0, "", "", "");
            return o;
The object returned is COM object (not managed code) then we can't use .NET reflection directly for exploring its methods and attributes .. I think we should use C++ and IDispatch interface, but i don't know how do this yet.
Hope it helps.

Dynamically Create Repeater Element in ActionScript

Hi,
I'm trying to dynamically create a repeater control with an
image and a label control. I can do it directly in the MXML file
but when I try and covert it into ActionScript it's not working.
Can anyone see what the problem is with my code?
public function GetPalettes():void{
removeChild(document.FrontPage);
Palettes.method = "GET";
params = {"method": "GetPalettes", "BodyPartNo":
document.PalettesMenu.selectedItem.@partNo};
Palettes.cancel();
Palettes.send(params);
var VerticalBox:VBox = new VBox();
VerticalBox.x = 10;
VerticalBox.y = 10;
VerticalBox.id = "VerticalBox";
var PaletteRepeater:Repeater = new Repeater();
PaletteRepeater.dataProvider =
"{Palettes.lastResult.Palette}";
PaletteRepeater.startingIndex = 0;
PaletteRepeater.id = "PaletteRepeater";
var PaletteImage:Image = new Image();
PaletteImage.setStyle("HorizontalAlign", "left");
PaletteImage.source = "
http://localhost/Flex/Personalised%20Palettes-debug/{PaletteRepeater.currentItem.@PictureS rc}Med.png";
PaletteImage.useHandCursor = true;
PaletteImage.buttonMode = true;
PaletteImage.mouseChildren = false;
PaletteImage.id = "PaletteImage";
var PaletteDescription:Label = new Label();
PaletteDescription.text =
"{PaletteRepeater.currentItem.@Description}";
PaletteDescription.id = "PaletteDescription";
document.MainPage.addChild(VerticalBox);
VerticalBox.addChild(PaletteRepeater);
PaletteRepeater.addChild(PaletteImage);
PaletteRepeater.addChild(PaletteDescription);
Thanks

What version of Flex are you using? The Help for Flex 3 has
this to say:
http://www.adobe.com/livedocs/flex/3/html/help.html?content=events_05.html
Defining event listeners inline
The simplest method of defining event handlers in Flex
applications is to
point to a handler function in the component's MXML tag. To
do this, you add
any of the component's events as a tag attribute followed by
an ActionScript
statement or function call.
You add an event handler inline using the following syntax:
<mx:tag_name event_name="handler_function"/>
For example, to listen for a Button control's click event,
you add a
statement in the <mx:Button> tag's click attribute. If
you add a function,
you define that function in an ActionScript block. The
following example
defines the submitForm() function as the handler for the
Button control's
click event:
<mx:Script><![CDATA[
function submitForm():void {
// Do something.
]]></mx:Script>
<mx:Button label="Submit" click="submitForm();"/>
Event handlers can include any valid ActionScript code,
including code that
calls global functions or sets a component property to the
return value. The
following example calls the trace() global function:
<mx:Button label="Get Ver" click="trace('The button was
clicked');"/>
There is one special parameter that you can pass in an inline
event handler
definition: the event parameter. If you add the event keyword
as a
parameter, Flex passes the Event object and inside the
handler function, you
can then access all the properties of the Event object.
The following example passes the Event object to the
submitForm() handler
function and specifies it as type MouseEvent:
<?xml version="1.0"?>

<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script><![CDATA[
import mx.controls.Alert;
private function myEventHandler(event:MouseEvent):void {
// Do something with the MouseEvent object.
Alert.show("An event of type '" + event.type + "'
occurred.");
]]></mx:Script>
<mx:Button id="b1" label="Click Me"
click="myEventHandler(event)"/>
</mx:Application>
It is best practice to include the event keyword when you
define all inline
event listeners and to specify the most stringent Event
object type in the
resulting listener function (for example, specify MouseEvent
instead of
Event).
You can use the Event object to access a reference to the
target object (the
object that dispatched the event), the type of event (for
example, click),
or other relevant properties, such as the row number and
value in a
list-based control. You can also use the Event object to
access methods and
properties of the target component, or the component that
dispatched the
event.
Although you will most often pass the entire Event object to
an event
listener, you can just pass individual properties, as the
following example
shows:
<?xml version="1.0"?>

<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script><![CDATA[
import mx.controls.Alert;
private function myEventHandler(s:String):void {
Alert.show("Current Target: " + s);
]]></mx:Script>
<mx:Button id="b1" label="Click Me"
click="myEventHandler(event.currentTarget.id)"/>
</mx:Application>
Registering an event listener inline provides less
flexibility than using
the addEventListener() method to register event listeners.
The drawbacks are
that you cannot set the useCapture or priority properties on
the Event
object and that you cannot remove the listener once you add
it.
don't see anything in there about anonymous functions...?

How to delete Dynamically created input field UI Element

Hi all,
 I want to delete dynamically created input field and label.
Is there any method please tell.
Thanks in advance
Hemalatha

Hi,
In the WDEVENT parameter of the action handler you can find the event id.
***Variables
DATA:
 lv_selected type string. "Selected tab value
***Structure and internal table for the Events and messages
DATA:
 lt_events type WDR_EVENT_PARAMETER_LIST,
 ls_events type WDR_EVENT_PARAMETER.
***Field symbols
field-symbols: <fs_value> type any. "Attribute value in events table
***Move the event table to lt_events
lt_events = wdevent->parameters.
read table lt_events into ls_events with key name = 'SAVE'. "Button Id
if sy-subrc eq 0.
 assign ls_events-value->* to <fs_value>.
 if sy-subrc eq 0.
 lv_selected = <fs_value>.
 endif. "IF sy-subrc eq 0.
endif. "IF sy-subrc eq 0.

Lekha.
