== Description ==

Starting from S60 3rd Edition, Feature Pack 2, it is possible to set TextBox to appear as a Pop-Up component in certain devices. This is done by using the JAR attribute and value <tt>Nokia-UI-Enhancement: PopUpTextBox</tt>.

<tt>TextBox.setMaxSize(int)</tt> can be used to set the maximum number of characters that the component can contain. If this limitation is set for a TextBox that contains an amount of characters that exceeds the maximum, the content of the TextBox will be truncated. 

However, in S60 5th Edition, <tt>setMaxSize(int)</tt> for a Pop-Up TextBox does not have the desired effect.


== How to reproduce ==

1. Implement a test MIDlet with a Pop-Up TextBox. You can use, for example, the following source code:

<code java>
 
 import javax.microedition.midlet.*;
 import javax.microedition.lcdui.*;
 
 public class SetMaxSizeTest extends MIDlet implements CommandListener{
    
    TextBox t;
    Display d;
    Command cmd;
    
     public SetMaxSizeTest(){
     
         t=new TextBox("Type here", "", 100, 2); // TextBox
         cmd = new Command("SetMaxSize to 2", Command.SCREEN, 0);
         t.addCommand(cmd);
         t.setCommandListener(this);
         d=Display.getDisplay(this);
     }    
    
    public void startApp() {
        
          d.setCurrent(t);
    }
 
    public void pauseApp() {
    }
 
    public void destroyApp(boolean unconditional) {
    }
 
  
 public void commandAction(Command command, Displayable displayable)
    {
 if(command == cmd)
                try
                {
                    t.setMaxSize(2); // maximum number of characters set to 2
                }
                catch(IllegalArgumentException iae)
                {
                   Display.getDisplay(this).setCurrent(new Alert("Exception thrown", iae.getMessage(), null, AlertType.INFO));
                }}}
</code>

In addition to the code, include the following JAD attribute and its value in the JAD file: 

<tt>Nokia-UI-Enhancement: PopUpTextBox</tt> 

2. Launch the application and type text that exceeds the <tt>setMaxSize(int)</tt> limit (here: 2) into the TextBox.

3. Select the '''SetMaxSize to 2''' command. On the affected devices, the text that exceeds the set maximum is not truncated.

== Solution ==

This issue is expected to be fixed in future S60 5th Edition devices.
