Is this is a bug of infoswing textfield?

any one suggest?
thanks in advance
anand mohan
It seems to be working OK for me. Here is the code that I use in a button to enable/disable a TextFieldControl object called controlID.
void jButton2_actionPerformed(ActionEvent e) {
if (controlID.isEnabled() == false) {
controlID.setEnabled(true);
else {
controlID.setEnabled(false);
I hope this helps.

Problem with expanding textfield in Adobe LiveCycle Designer
I've got an urgent problem with Adobe LiveCycle Designer and I really could use some help. The problem is that I'm trying to get my textfield expandable, but whatever I try, it's not working. What I'm trying to get done is that you can fill in a textfield, and when there is more text than the size of the field, the textfield expands to make the text fit in the field.
I tried a whole lot of things:
placing the textfield in a subform
expand to fit (height)
allow multiple lines
allow page breaks
flowed/positioned
etc.
The strange thing is, that no matter what I try to adjust, I can't change anything in the pagination tab. Maybe that is the problem, but I don't know what to do, to change that.
In the examples of Adobe itself (Purchase Form) is an example of a textfield that sort of behaves as I want it to, BUT the problem is that that textfield in the subform has to be triggered to appear by a button (add comments) and that is what I don't want. I want the textfield to be visible from the beginning. But in that example you CAN see the pagination tab and make changes in it.
I searched a lot in the Adobe Helpfiles of Designer, and I even bought and read/studied the book 'Creating Dynamic Forms with Adobe LiveCycle Designer', but still I'm not able to get this done.
Is there anyone who can help me?
Thanks in advance,
SterreI am creating my first .pdf with no training. I first converted a word doc of our form into a .pdf. Modified everything and thought I was the "bomb" for figuring it out. Then I tried to use the form and where I had "allowed multiple lines" I realized that it would allow that but not display it or print it except for what was showing.
In researching for a solution, this site said to use "expand to fit". After much frustration I realized that this feature is only available if you created the form from scratch in adobe.
I have figured out, somewhat, how to create the form and get the field to move with the text but I need the entire form to adjust to the input. Can't have one specific field expand into the rest of the form.
I did some more research on this site, and it looks like the solution has something to do with 'subforms'. No idea what to do.
If anyone knows if there is a way to do this with a converted doc (since I already have that completed) I would GREATLY appreciate it. If it isn't possible, could someone walk me through how to do it or provide a reference for a "barney style" walk through?
Appreciate ANY assistance you can provide. THANKS! Guess I need to sign up for an Adobe Pro class. BTW I'm working on LiveCyle 8.0 -
Problem with InfoSwing comboboxes
I posted a message earlier concerning JDeveloper 2.0's InfoSwing
ComboBoxControl. I have a little more information that might
help someone who has used JDeveloper figure the problem out. The
problem is that I place the combobox controls on my form and set
the dataItemName and dataItemNameForUpdate properties but when I
run the applet and click on the combobox, the list doesn't show
up. In fact, I get the following error:

nullNo Joel,
it seems that the JDev Team is unable to give a proper support
for their product. I wouldn't have been able too if I had
released a product with a bugs like that (e.g. combo boxes not
been able to populate). May be this is the reason Oracle is in
such a hurry trying to release JDeveloper 3.0. Well, let's hope
the bugs in the new version will decrease rather than increase.
For now I would suggest to you to try Symantec's Visual Cafe or
even Borland's JBuilder may suit what you need.
BTW, I left the ideas to finish my project using Java and went
back to the more stable combination Perl/CGI/HTML.

Problem with Import and Base Object
Hi everyone
Last week, I downloaded Flash CS5. I am trying different thing and here is the problem that I dont understand
I wrote a package like that
package {
import flash.text.TextField;
import fl.controls.Button;
public class ex1 extends Sprite {
public function ex1() {
var myButton:Button = new Bu
tton();
var label:TextField = new TextField();
addChild(label);
If I try to execute that script, the compiler returns error
1046: Type was not found or was not a compile-time constant: Button.
1180: Call to a possibly undefined method Button.
If I insert in the main stage (with the Componet Editor) a Button in the main stage, and recompile it, no error.
If I delete the Button in the main stage and recompile again, no error
But, If I save the projet and reload it again, I've got the same error
By the way, I dont have any problem with the textField()
What is wrong with my setup.
OTHER QUESTION:
If in the ACTION FRAME (F9), I insert the folowing code:
import ex1;
var a:ex1 = new ex1();
one more time, I've got error from the compiler. Why ?
We cannot include a package in the ACTION FRAME ?
Thanks for your helpThere are some things (including $.fileName) that just do not work in jsxbin's.
I don't thing the exception hook will work either.
Either use an ini file in a well known location (~/Desktop) or make sure your
files are put in Presets/Scripts. That location can be determined with this bit
of code:
var SCRIPTS_FOLDER =
new Folder(app.path + '/' +
localize("$$$/ScriptingSupport/InstalledScripts=Presets/Scripts"));

Problem with TextField formatting
I'm having a little bit of a problem with this very basic bit
of code. The following code works fine: (I apologize for not having
it in a format that may be more suitable)
this.createTextField("my_text", this.getNextHighestDepth(),
10, 70, 400, 100);
my_text.text = "This is my TextField.";
//my_text.embedFonts = true;
However, for some reason, this doesn't work. I'm baffled by
why uncommenting this simple line of code makes it not show up:
this.createTextField("my_text", this.getNextHighestDepth(),
10, 70, 400, 100);
my_text.text = "This is my TextField.";
my_text.embedFonts = true;
Any help would be appreciated.My guess is that you forgot a few things to work with
embedded fonts...
1) Have you embedded the font you want to use inside your
library and given it a unique id.
2) If you did #1, try this... -
GUI problem with textfields, reading in text from a textpad
Alright well, here is my problem. I am having trouble with aliging the textfields to how I want it but I can't get it to come out how I want it. First, I am trying to figure out how to have the some text appear right above a textfield. Example:
File Name
I can't get it appear that way, the text appears side to side with the textfield. And the other problem is how can I made the size of textfield to how I want it. I was reading that you have to assign a specfic number in the text field.
This is the code I have so far:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class IP_Header extends JApplet
private JTextField lookUp, showInfo;
private JButton analyze;
private JLabel msg;
public void init()
JPanel p1 = new JPanel();
p1.setLayout(new GridLayout(3,2));
p1.add(new JLabel("File Name"));
p1.add(lookUp = new JTextField());
p1.add(analyze = new JButton("Analyze"));
p1.add(showInfo = new JTextField());
msg = new JLabel(" ");
Container cp = getContentPane();
cp.setLayout(new BorderLayout());
cp.add(p1, BorderLayout.NORTH);
With this what I am tryin to do is as follows:
File Name
* "TextField" * *
**************** * This is a textfield where I am just going to
* have some text appear in it
* "Button" * *
Thank you for your help. I hope you can help me. I haven't done java for a quite a while. Thanks againThanks for help ... really helpful and understanding. I am trying to read a file from the computer which has some numbers in it and I want those numbers to be shown on the textfields individually. The numbers are in a notepad file and they are .... 4, 5, 200, 780, 1, 0, 0, 12, 6, 0, 129, 24, 21, 44, 133, 62, 159, 7. I got the program to compile and everything by adding the code that I believe should work . But whenever I put the file name in and press the button analyze ... it gives me a error saying "Exception: access denied (java.io.FilePermission c:\TCP read) .. can't quite get it ...here the code:

Problems with TextField in Window (jre 1.4.2)
Hi,
I have a problem with the following code, which used to run o.k. on older vm's:
<CODE>
import java.awt.*;
import java.awt.event.*;
class TFTest extends Window {
public TFTest(Frame frame) {
super(frame);
TextField tf = new TextField("Hello!");
tf.setEditable(true);
tf.requestFocus();
add(tf);
public static void main(String args[]) {
System.out.println("Starting MAPP ParentGui...");
Frame frame = new Frame("TFTest");
TFTest mainFrame = new TFTest(frame);
mainFrame.setSize(240, 320);
mainFrame.setVisible(true);
</code>
The TextField doesn't seem to become editable whatever I change....
gr,
PeterTwo problems:
1. You must make parent Frame visible to make child Window focusable(see Javadoc for Window.isFocusable)
2. You request focus on the component before adding it to the top-level. Make sure you first add component, then request focus on it. -

Best regards,
TobiasHi Tobias,
I assume you are currently using "Contains & Case Sensitive" for the "Search" attribute. Have you already tried out "Exact & Case Sensitive"? Because that will internally use the LIKE operator as your original query does and because the % is at the end it should enable the use of an index. But it might still not work, because the ORDER BY might be executed at a different time than in your original example, but it's worth a try.
Regards
Patrick

HTML Textfield Problem with Image Positions/Image Tag img
I am using :
Flash Builder Burito - Flex Hero SDK - Air 2.5 - Flash Player 10.1
Hi,
i have a problem with the normal Textfield.I'm loading html text into it and apply an css stylesheet on it. Everything works fine, but if there is an <img> in the html code, the image is displayed at the wrong position (top left).
It looks like the Problem is only in Air Applications. I tried the exact same code in an normal actionscript project and tested it in the broweser. Here the images are at the right position.
Does anybody else has this problem in Air or knows a solution to this?
Thanks. Laurid
btw: I tried it on Windows 7 and Android with the same problem.Okay, I think I found the solution myself:
http://www.kirupa.com/forum/showthread.php?t=322233
For AIR content in the application security sandbox, AIR ignores img tags in HTML content in ActionScript TextField objects. This is to prevent possible phishing attacks,
This does not make any sense to me. Can somebody please explain it to me? I can load images with the loader-class and combine it with my html text. The only thing which does not work is that the text is wrapping aroung the images. So why does this prevent phishing attacks?
For me this doesn't make sense at all. It's just annoying that you develop an application in Flash and that it's not working the same way in Adobe Air. Now I have to find a complicated work-around myself. Or does anybody know how I can easily wrap text around images?
Thanks. Laurid -
Problems with the selection of text or objects
dear fireworks community!
unfortunately i have problems with my running version fireworks (CS6) and i can't find any solution or even get help via the customer support.
i can't switch between objects with a click, when i've choosen one already. i also can't cancel the entire selection. the only way (to select a new item) is to click on an empty space, hold it and pull the selection over a new item.
another thing is that i cant select a textfield with a doubleclick or switch beteween choosen tools within the usage of a shortcut …
what i already tried:
updating, deinstalling, re-storing preferences, "cleaning" the libraries, installing (this entire scenario for at least three times)
i hope someone of you can help me!
thanks in advance!incredible!
thank you so much! -
Problem with focus and selecting text in jtextfield
I have problem with jtexfield. I know that solution will be very simple but I can't figure it out.
This is simplified version of situation:
I have a jframe, jtextfield and jbutton. User can put numbers (0-10000) separated with commas to textfield and save those numbers by pressing jbutton.
When jbutton is pressed I have a validator which checks that jtextfield contains only numbers and commas. If validator sees that there are invalid characters, a messagebox is launched which tells to user whats wrong.
Now comes the tricky part.
When user presses ok from messagebox, jtextfield should select the character which validator said was invalid so that user can replace it by pressing a number or comma.
I have the invalid character, but how can you get the focus to jtextfield and select only the character which was invalid?
I tried requestFocus(), but it selected whole text in jtextfield and after that command I couldn't set selected text. I tried with commands setSelectionStart(int), setSelectionEnd(int) and select(int,int).
Then I tried to use Caret and select text with that. It selected the character I wanted, but the focus wasn't really there because it didn't have keyFocus (or something like that).
Is there a simple way of doing this?textField.requestFocusInWindow();
textField.select(...);The above should work, although read the API on the select(...) method for the newer recommended approach on how to do selection.
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)",
see http://homepage1.nifty.com/algafield/sscce.html,
that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting. -
Problem with writing and reading using serialization
I am having a problem with writing and reading an object that has another object in it. The purpose of the class is to write a order that has multiple items in it. And there will be several orders. This is for an IB project, where one of the requirements is to utilize a hierarchical composite data structure. That is, it is "one that contains more than one element and at least one of the elements is a composite data structure. Examples are, an array or linked list of records, a record that has one field that is another record, or an array". The code is shown below:
The error produced is

Problem with PropertyChangeListener and JTextField
I'm having a problem with PropertyChangeListener and JTextField.
I can not seem to get the propertychange event to fire.
Anyone have any idea why the code below doesn't work?
* NewJFrame.java
* Created on May 15, 2005, 4:21 PM
import java.beans.*;
import javax.swing.*;
* @author wolfgray
public class NewJFrame extends javax.swing.JFrame
implements PropertyChangeListener {
/** Creates new form NewJFrame */
public NewJFrame() {
initComponents();
jTextField1.addPropertyChangeListener( this );
public void propertyChange(PropertyChangeEvent e) {
System.out.println(e);
/** This method is called from within the constructor to
* initialize the form.
* WARNING: Do NOT modify this code. The content of this method is
* always regenerated by the Form Editor.
private void initComponents() {
jTextField1 = new javax.swing.JTextField();
jScrollPane1 = new javax.swing.JScrollPane();
jFormattedTextField1 = new javax.swing.JFormattedTextField();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
jTextField1.setText("jTextField1");
getContentPane().add(jTextField1, java.awt.BorderLayout.NORTH);
jFormattedTextField1.setText("jFormattedTextField1");
jScrollPane1.setViewportView(jFormattedTextField1);
getContentPane().add(jScrollPane1, java.awt.BorderLayout.CENTER);
pack();
* @param args the command line arguments
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new NewJFrame().setVisible(true);
// Variables declaration - do not modify
private javax.swing.JFormattedTextField jFormattedTextField1;
private javax.swing.JScrollPane jScrollPane1;
private javax.swing.JTextField jTextField1;
// End of variables declaration
}If you want to listen to changes in the textfield's contents you should use a DocumentListener and not a PropertyChangeListener:

And please use [co[/i]de] tags when you are posting code (press the code button above the message window). -
Problem with Javascript in JSP
Hi Guys,
I have this problem with my JSP page. I am using a javascript function
which calls a function within a bean. The problem that I have is that I get an error when trying to call the following function :
function refDataTypes_onchange()
Vector empNames = DBQuery.getResult();
I get a runtime error at the line Vector empNames = DBQuery.getResult;
Any ideas would be much appreciated.
Below is the whole code:
Thanks in advance
FRank
<%@ page contentType="text/html;charset=WINDOWS-1252"%>
<%@ page import="java.util.*, java.lang.*" %>
<%-- Declare the java bean for the countries to be queried --%>
<jsp:useBean id="DBQuery" class="DBQuery" scope="page" />
<%-- Bean property searchCondition is not set to query countries --%>
<jsp:setProperty name="DBQuery" property="searchCondition" />
<%
Vector empNames = DBQuery.getResult();
%>
<HTML>
<BODY BGCOLOR="GREY">
<SCRIPT LANGUAGE="JavaScript1.1">
function refDataTypes_onchange()
Vector empNames = DBQuery.getResult();
</SCRIPT>
<FORM NAME = form1>
Please enter in the following details
<p>
Reference Type :::====
<select name="refDataTypes" onchange="refDataTypes_onchange()">
<option value ="1"></option>
<% for(Enumeration enum = empNames.elements();enum.hasMoreElements();)
String nextEmpName = (String)enum.nextElement();

</HTML>Thanks dimadoo
I need my JSP to do the following :
When a user selects a option from a select list. There is a textfield which I want to populate based on the option that thas been selected from the list.
I tried the following :
<% Vector empNames = DBQuery.getResult(); %>
and it does not even go into the bean.
Will this work if I refresh the page? -

Best reguards
Misalrighty then try this xml structure.
Note: formatting information like b, or linkage tags should
not be part of the xml.
The XML format is a universal format for data, if you fill it
with style information this is not good practive (in general, there
are of course scenarios where it makes sense, also since (x)html IS
also XML).
In your case you want to put the information about multiple
companies in a xml file, but you let the flash decide how to
display format this information.
so if you use the sugested XMl structure you will have full
control of the layout within flash, because you can grab every
piece of information from the xml and place it jsut where you want
in flash and format it within flash.
Of course this process is more coding work than your previous
attempt, but it pays of when you have a lot of data to process and
when you want to have full control of the final layout.
But maybe its overkill for your application (I don't know how
many companies will be stored in your xml and how complex the rest
of the app is).
Maybe you are looking for
