Creating A Class For A ComboBox Component

I have a comboBox component that I would like to create a
class for. But I am not sure if I could. I see how you can use the
Linkage window to assign an AS 2.0 Class to a movie clip, but I do
not see that same option for a comboBox component.
It has all of the basic combo box things that I would like to
seperate out into it's own class if possible
If anyone could give me a few tips, or better yet, point me
to a few good tutorials, that would be great.
Thanks
Mathias

How to create proxy class for a Siebel WS which has many Workflows in it?

Hi,
I am facing a strange problem. I have a Web Service for which there are many workflows associated with this. When I generate WSDL for this Web Service and later on generate proxy class in .NET, it creates mutilple classes for each workflow. From UI, I can invoke a perticular method for the class for which I am interested in. But when I am building the same in JDeveloper, using Web Service proxy, I get only one class and I am not interested in invoking method in this class but interested in some other class for which the proxy was not generated. Is there some way to generate multiple classes in JDeveloper proxy?
Thanks,
Sudha.

I have figured this out. Actually Generate proxy creates package and it includes all the class in it. Now i am able to invoke web service method call.

How do I create Wrapper class for Message Box?

I want to create Wrapper class for Message Box class in my project. I am using Telerik Testing FrameWork. In that message box was not recognized in unit testing thats y i want to create wrapper class, for creating the
instance for that mesage box.

A wrapper class is simply a class that for example wraps another object or a subset of its methods. You could just create a class that exposes the same methods as the MessageBox and uses the MessageBox internally.
If you define an interface and program against this in your application, you could replace your wrapper object with another object that implements the same interface when you are doing the unit tests. Something like this:
public interface IMessageBoxWrapper
System.Windows.Forms.DialogResult Show(string text, string caption);
public class MessageBoxWrapper
public System.Windows.Forms.DialogResult Show(string text, string caption)
return System.Windows.Forms.MessageBox.Show(text, caption);
public class MockMessageBoxWrapper
public System.Windows.Forms.DialogResult Show(string text, string caption)
return System.Windows.Forms.DialogResult.OK;
private readonly IMessageBoxWrapper _mbw;
public Form1(IMessageBoxWrapper mbw)
InitializeComponent();
_mbw = mbw;
private void SomeMethod()
_mbw.Show("...", "...");
Hope that helps.

Actionscript for the ComboBox Component

I'm trying to write a basic script for the ComboBox Component
that opens a URL when the user clicks on one of the labels in the
drop down menu. I know how to do this with regular instances, but
how can I do this with this component? I'm hoping that I'll be able
to make each label lead to a different URL.
Any help is appreciated.
Thanks

Frank,
My declarative component is dropped on my jsff. In this pages i have dropped a af:messages as well.
There is a small button in my component on which i have bound an action listner.
In the action listener i have a validation on the failure condition of which i have the code like:
if(bean == null || bean.isAuthenticated() == false){
FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "You must be logged in to vote up");
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(getVotingQuesComponent().getClientId(context), msg);
AdfFacesContext.getCurrentInstance().addPartialTarget(getVotingQuesComponent());
return;
So, i m sure my flow is going in this part of code but i dont see the message coming up marking my declarative component.
However, if i replace this message by a page level error message then that comes up fine.

How can I determine the feeder class for a WebDynpro component in SRM 7.0?

Hi experts.
I am trying to figure out how to add some columns to the list of contract items for this WebDynpro application/view:
Applikation: /SAPSRM/WDA_L_FPM_OIF
Web Dynpro-komponent: /SAPSRM/WDC_CTR_DOTC_IT
Window: IV_L_FPC_CA_TREE
View: V_CTR_DODC_ITEMS
Configuration-ID: /SAPSRM/WDCC_FPM_CTR_DOTC_ITM
All the documentation I can find regarding the FPM says to change the feeder class, but nowhere I have seen do they explain how to determine the feeder class of an existing component/view.
I am hoping for your help!
Thanks!
Best regards
Per Hjorth Christiansen

The term "feeder class" normally refers to the POWL search, not the actual document detail screen. You could just add one more column by enhancing the webdynpro view.

Create item class for Number values

Hi Rod
I rarely use Desktop and neither do my customers, unless they are on versions of Discoverer prior to 10.1.2. Time and time again I have taught 10.1.2 Plus / Viewer to dyed in the wool Desktopees to finish the course for them to say that they are never going to use Desktop again.
One of the many issues with Desktop is the caching and even though it can do some things that Plus cannot, the many features in Plus that don't exist in Desktop far outweight them.
What do you think? Do you still see a use for Desktop?
How about everyone else? I would love to hear from you.
Best wishes

How can you specify a custom style class for an ADF component (column)?

We are using ADF 10_1_3_3_0 on Tomcat.
We would like to specify an additional style class for a column header. We have specified the following style:
{color:#808080}af|column.formHeader::header-text
text-align: right;
background-color:brown;
border-color:#999999;
font-family:Verdana,Arial,Helvetica,sans-serif;
color: blue;
}{color}
{color:#808080}<af:column sortable="true" formatType="text" styleClass="formHeader">{color}
This does not seem to work. In our tests, the CSS gets generated but the new style class for the column header does not seem to be generated/mapped. I reveiwed this post: Re: Jdev 11g: how to set width of some components on panel form layout. Is this specification (component.className::selector) applicable for the 10g version of ADF?
Additionnaly, are their specifcations/details for these selectors (e.g. ora-rule-ref, -rt-rule-ref, -tr-rule-ref). I am not clear on what they are mapped to and how they are used.
Thanks
Edited by: user10477345 on Oct 27, 2008 6:48 AM

Hi,
The column's style classes will be added on the <td> elements, not the header sadly. So for your use case you'll have to place the class on the table itself then use the selector
af|table.MyStyleClass af|column.formHeader::header-text{}Sadly this will affect all columns, not just one so I don't know if it's going to fir your need.

I have a stored procedure that has PERSON_TAB as a OUT parameter. How do retrieve the value from callablestatement? Is there a sample code anywhere. Kindly direct me.

CREATE EDITION CLASS FOR PAGE FORMAT

Hi,
I have a sales form in SapScript, for which I created a page format "ZFCONT" in continuous form (305 mm. x 225mm.).
Now the system needs to create a "editing class" to associate the new page format (ZFCONT).
What are the steps to create the "editing class".
There is another necessary step to enable it to print?
Thank you very much for your help.

Well, this should be a system problem (refresh) because the day after, without any change in SPAD nor anyplace else, the smartforms is recognizing the page type I've created.
Thanks anyway.

Creating search field for a list component

i have created a glossary of terms using the list component and populating it via an XML file.
what i would like to do is create a search field that as the user types in the search bar if there are any matching entries in the list, the focus/selection jumps to that particular item in list. i don't want to clear the list just go to the item that matches.
i would like it to be predictive so if i have these entries:
samson
seek
seether
south
and the user types "s" in the search box to the first "s" entry in the list (samson) is selected, if they type "se" the selection jumps to the first entry with "se" in it (seek) if they type "seet" the selection jumps to "seether" and so on.
i have absolutely no idea how to do it, but more importantly...is this possible?
i have attached the sample files that i have been working on.
thanks in advance

You need the lowercase. the keyCode of the keybpardevent returns the key's uppercase charcode. So the A-key allways returns 65. Therefore convert keycode to char and to lowercase before appending after what's allready there in the field.
To have the user not have to type the words with proper casing, convert the label to lowercase before doing the indexOf search.

I don't understand, Why you try to create new Label in getLabel constructor?
You get label class already extended from JLabel and don't necessary to create new JLabel.
public getLabel( String labelName, int x, int y, int width, int height, Color foreGround,
                               String fontName, int fontStyle, int fontSize ){
               super(labelName);
               this.setBounds( x, y, width, height);
               this.setForeground(foreGround);
               this.setFont(new Font(fontName, fontStyle, fontSize));
          }I think, you need to create ControlsFactory and use it for creating custom controls. It's best solution for you.

Create Custom Controls Programmatically
You can create custom controls by using either of the following approaches:
•     Extend the CustomNode or Control classes.
•     Apply CSS styles and provide a custom skin.
The following code fragment illustrates the first approach by creating a custom UI control with an image.
class MyControl extends CustomNode {
    var button: Node[];
    var image: Image;
    override function create() {
        HBox {
            spacing: 5
            nodeVPos: VPos.CENTER
            content: bind [button, ImageView {image: image}]
