    public HtmlOutputText getOutputText1() {
        return outputText1;
..........(more code)....
}If I run the page twice without checking if the component existe before adding it, it says that it have found the component duplicated in the view.
"javax.servlet.jsp.JspException: Id. de componente duplicado 'form1:patitoPerez' hallado en la vista."
so the code is working but it is not rendering the input text in the page.
any ideas?

My bad.
I didn't explain the reason for this aproach.
The thing is that I want to do a single page that handle de CRUD for a set of tables, but the number of fields of the table isn't constant, so I need to add the fields programmatically to make the screen just for the table.
I've resolved the issue, maybe it's a bug, the thing is that the code only function if the page it's a .jsfx.
Greetings.
Thanks for the reply.

Jsf data table component + print null cell

I am using the jsf data table component and binding the column values to a backing bean.
<h:dataTable binding="#{backing_showDifferences.dataTable2}"
id="dataTable2">
<h:column binding="#{backing_showDifferences.userColumn1}"/>
<h:column binding="#{backing_showDifferences.userColumn2}"/>
<h:column binding="#{backing_showDifferences.userColumn3}"/>
</h:dataTable>
- some code from my showDifferences.java
HtmlOutputText column1Text = new HtmlOutputText();
vb =
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{users.uclass}");
column1Text.setValueBinding("value", vb);
usercolumn1.getChildren().add(column1Text);
HtmlOutputText column2Text = new HtmlOutputText();
vb =
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{users.ue1}");
column2Text.setValueBinding("value", vb);
usercolumn2.getChildren().add(column2Text);
HtmlOutputText column3Text = new HtmlOutputText();
vb =
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{users.ue2}");
column3Text.setValueBinding("value", vb);
usercolumn3.getChildren().add(column3Text);
ResultSetDataModel dataModel = new ResultSetDataModel();
dataModel.setWrappedData(rs);
dataTable2.setValue(dataModel);
The raw HTML:
<table id="form1:dataTable2" class="iuptable" border="1">
<thead>
<tr>
<th scope="col">Heading 1</th>
<th scope="col">Heading 2</th>
<th scope="col">Heading3</th>
</tr>
</thead>
<tbody>
<tr>
<td>some data in this column</td>
<td>X</td>
<td></td>
</tr>
<tr>
<td>Some more data in this row</td>
<td>X</td>
<td></td>
</tr>
</tbody>
</table>
My problem is this...in the raw HTML the <td></td> tag is not formatted nicely on my table output. I have lines around my entire table and each cell within it. When the <td></td> prints there are no lines. I am new to the JSF table data component, but if I were writing some JSP or servlet code I would check that if value was null I would append an &nbsp to the <td> tag (ex. <td>&nbsp</td>) and the table would be formatted properly. The backing bean that I am binding to is pulling the data from a database table...so my sql looks like this:
SELECT uclass, ue1, ue2 from table1; my problem is when ue1 or ue2 is a null value.
Any ideas would be greatly appreciated!

Hi,
the h:dataTable belongs to the JSF Reference Implementation from Sun, not to Oracle ADF Faces. The rendering is within this component set and I suggest to report your issue on one of the SUN forums (http://forum.java.sun.com/forum.jspa?forumID=427) as we have no handle to e.g. fix an issue if it exists in the component set.

Very Simple: How do I programmatically add line breaks?

Very Simple: How do I programmatically add line breaks or how do I encapsulate my RichCommandLink's within a paragraph?
My Code is as follows:
for (String token : userViews.getViewNames())
// add command link
RichCommandLink output = new RichCommandLink();
output.setText(token);
// set action here
// output.setActionExpression());
viewItem.getChildren().add(output);
// update view
this.menuAccordion.getChildren().clear();
this.menuAccordion.getChildren().add(0, viewItem);
AdfFacesContext.getCurrentInstance().addPartialTarget(getMenuAccordion());

Sorry, I'm using Jdeveloper 11.
Im using JSP, JSF, ADF, Fusion. The RichCommandLink is an ADF Control.
My PanelAccordion is bound to a RichPanelAccordion in my java class. When I add RichCommandLink's to the accordion the items are added next to each other. How do I add line breaks from my java class?

How to programmatically add rectangle to a pdf file ?

How to programmatically add rectangle to a pdf file ?
There is several page pdfs, non-vector, black and white.
Users are color blind and have disabilities.
To train them, one adds a rectangle at a certain lower-left point and width,height specified for a page.
The idea is to give the script the page and coordinates and size of rectangle to be added programmatically. Green rectangles are acceptable as the cones are most sensitive there.
Also, additional feature to add bookmarks on the left in the order these rectangle data is provided to the script.
The script could be "hard-wired" by a list of the rectangle coodinates, and page number, pasted inside acrobat and run or entered into acrobat in some way.
Your script would help many disabled people who are distributed through out the world.
Feel free to contact me by email if you wish.
Dying Vets

P.S.
This rectangle does not have to be a full annotation rectangle which needs user,date and a lot of info.
Something minimal like this would suffice
1 0 0 RG % red for stroke color
200 300 50 75 re
As you can see that the native unit of the pdf file is the "point" having 72 in an inch.
The file dpi would be given. However, one could assume that pixel for the rectangle lower-left and width/height are given.
From the pixels and dpi, the points could be calculated if desired.

Add component in task list

Hello All,
I have an issue with adding component in task list (for example task list number EIMN-68) via transaction IA05.
When I try to add component to operation, I get the message *
Standard BOM PAEIMN-68 4 already exists
Message no. 29771
Diagnosis
You want to create a standard BOM for standard object PAEIMN-68 with usage .
A BOM already exists for this standard object and usage. You cannot extend a standard a standard BOM.
Procedure
Check whether the standard BOM is suitable for standard object PAEIMN-68 and usage . If it is not, you need to create the BOM for another standard object.
Is there any special way to create material master for such components.Whats the solution.
Please help
Cheers
Sunny

Hi Pithan, how are you..
I want to add components.
Just now I was able to add components. I explain how:
When i added component number in operation, and press enter, system gave me the error that standard bom already exist. In the same screen I changed the BOM usage to 3 as universal usage. After this usage only, system allowed me to add components. No other bom usage allowed me to do so.
Also, why system took me to BOM screen if I just want to add components.
I wait for your reply.
thanks and regards
Sunny

Facing problem to add component in a panel dynamically

I face serious problem to add component dynamically on a jpanel. can any one help me?
I have one panel inside a frame. And I have another 3 or 4 panel. dynamically i want to change the panel inside the frame with the other panel.
can anybody help me with source code?
Your earliest response is highly appreciated.

remove is reflected immediately without calling

give me some code.Post a small demo code that is generally compilable, runnable and could reproduce your problem. See: http://homepage1.nifty.com/algafield/sscce.html and http://www.yoda.arachsys.com/java/newsgroups.html

How to programmatically add UDVs to project?

Hi all,
I have successfully used something like this to programatically add shared variables to an LVLIB (the code assumes that the library associated with the Container Reference contains at least one variable):
An example output would be:
Container Name: "MyLibrary.lvlib"
Variable Name: "Variable1"
Variable Path: <blank>
Variable Type String: "Variable"
(I notice that there is no way to specify the data type of the variable, and LabVIEW creates a DBL variable in the LVLIB by default.)
However, if Container Reference is associated with a "User-Defined Variables" container, then I get Error 1 at the Invoke Node ("LabVIEW: An input parameter is invalid"). A example output is:
Container Name: "User-Defined Variables"
Variable Name: "Variable1"
Variable Path: <blank>
Variable Type String: "Variable"
Questions:
Does the error occur because LabVIEW is trying to create a DBL variable (which is not allowed with UDVs)?
How can I programmatically add UDVs to my project?
Thanks in advance!

What is the scope of your project? How will you be using these UDV's?

Dynamic add component to panel, it does't work

I want to add a label in a panel when you click button.
I used revalidate() and revalidate() method, but it didn't appear in panel.
HELP ME?? WHAT'S WRONG!
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
jPanel1.add(new JLabel("Hello"));
jPanel1.revalidate();
jPanel1.repaint();
}

i add Layout manager to panel. It works. Thanks,
So tricky things for dynamic adding component:
1, setup layout manager to container (such as panel),
2, add component to container
3, call revalidate() method to relayout these components in container
You can't miss any one of those.
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
jPanel1.setLayout(new FlowLayout());
jPanel1.add(new JButton("Hello"));
jPanel1.revalidate();
}

Render Related -JSF Third party Component

Hai All
I am having doubt regarding JSF Third party component like Jmaki ,MyFaces or something like that . How the third party component match with JSF life cycle even though there is no java classes for managing and rendering the Third party component . what i basically mean to say is if we use <h:inputText> in our JSF page , the inputText component will managed by many java class like UIInput.class and HtmlInputText and InputTextRender and so on. next if we use dojo.dropdowndatepicker ,there is component for managing this component like UIDate, HtmlData .
could you tell me how third party component working without any problem.
Thanks for advance

If you look in the jar files for the libraries, you will find a faces-config.xml file containing such configurations.

How to programmatically add af:setPropertyListener to CommandImageLink

Hi All,
My Requirement: programmatically add af:setPropertyListener to CommandButton
I referred this post how to programmatically add af:setPropertyListener to CommandButton and followed the following code.
Code:
// create a value expression
ValueExpression vx =
elFactory.createValueExpression(elContext, "#{pageFlowScope.clockNo}",
String.class);
// set a default value if desired
vx.setValue(elContext, clockNo);
SetPropertyListener spl =
new SetPropertyListener(ActionEvent.class.getName());
spl.setFrom(clockNo);
spl.setValueExpression("to", vx);
// add the listener to the button
newOpButton.addActionListener(spl);
My Code:
<af:commandImageLink id="editInsuraceDetLink"
icon="/resources/images/Edit.jpg"
iconPosition="trailing"
rendered="#{not row.deleted}"
action="addEndorsement"
useWindow="true"
inlineStyle="vertical-align:bottom;"
partialSubmit="true"
shortDesc="Edit"
*actionListener="#{pageFlowScope.GetEndorsementTypeListener.execute}"*
returnListener="#{GetEndorsementDetailsListener.execute}"
windowEmbedStyle="window"
windowModalityType="applicationModal"
windowHeight="650" windowWidth="740">
</af:commandImageLink>
Action Listener - .GetEndorsementTypeListener.execute code:
RichCommandImageLink a_button = (RichCommandImageLink) a_component.findComponent("editInsuraceDetLink");
FacesContext fctx = FacesContext.getCurrentInstance();
Application application = fctx.getApplication();
ELContext elContext = fctx.getELContext();
ExpressionFactory elFactory = application.getExpressionFactory();
ValueExpression vx = elFactory.createValueExpression(elContext, "#{pageFlowScope.controlFlowName}", String.class);
// set a default value if desired
//vx.setValue(elContext, clockNo);
SetPropertyListener spl = new SetPropertyListener(ActionEvent.class.getName());
spl.setFrom(a_target.getEndorsementFor().toString());
spl.setValueExpression("to", vx);
System.out.println("From= "+spl.getFrom());
System.out.println("To= "+spl.getValueExpression("to"));
// add the listener to the button
a_button.addActionListener(spl);
I got the following output.
From= Nominee / Appointee
To= ValueExpression[#{pageFlowScope.controlFlowName}]
Now my Problem is: the pageFlowScope variable ControlFlowName is not set.
And also I got a *link*: https://blogs.oracle.com/vijaymohan/entry/usage_of_setpropertylistener_and_setactionlistener
Whats wrong with my code. Is my problem related with above *link*.
Please suggest me how to add SetPropertyListener programmatically.
-Thanks
Mohanraj

Frank,
This works:
        // create a value expression
        ValueExpression vx =
            elFactory.createValueExpression(elContext, "#{pageFlowScope.clockNo}",
                                            String.class);
        // set a default value if desired
        vx.setValue(elContext, clockNo);
        SetPropertyListener spl =
            new SetPropertyListener(ActionEvent.class.getName());
        spl.setFrom(clockNo);
        spl.setValueExpression("to", vx);
        // add the listener to the button
        newOpButton.addActionListener(spl);But, I am thinking you would have known about it before I posted it. I don't really know how it works, but it does.
Can you help me reconcile between this, and what you said. Because what you said makes sense too.

Programmatically add front panel objects

hello,
I would like to programmatically add controls and indicators to a front panel. I have read a thread:
http://forums.ni.com/ni/board/message?board.id=170&message.id=70347&query.id=10819#M70347
Ben Rayner describes a technique which takes an image of the relavant object, then adds this image to a picture on the front panel. I was wondering if anyone has an example of this techinique? Or if there is a simpler method of doing it?
Thanks,

Hi Paul,
This thread contains a collection of Picture related threads.
Contained in that collection you will find a link to this thread where in reply #52 I posted an entry for the "Obfuse Code Challenge" . In that example I grab the image of a boolean and use it in a Picture control to play a game of Hang Man" while executing a random walk to speel out "Hello World". That code is not documented since the game was to be obfuse.
In reply #33 of this thread, I posted a new version of the CC and Friends" project where I used a picture control to display an arbitrary set of images.
Ading to the above:
I have developed and delivered "Controls on the Fly" applications
add they were well recieved, BUT....
They are not trivial!
So if you would like to share what you are trying to accomplish, we may be able to makes suggestions that are esier to implement.
