Problem with TableModelListener - it's just not working

Hi all - I have a TableModelListener like the one bellow but when I edit data in the table and press enter nothing happens - I'm guessing I'm doing something wrong but I can't work out what - has anyone got any ideas?
teamManageTable.getModel().addTableModelListener( new TableModelListener() {
            public void tableChanged(TableModelEvent e) {
                int row = e.getFirstRow();
                int column = e.getColumn();
                TableModel model = (TableModel)e.getSource();
                String columnName = model.getColumnName(column);
                Object data = model.getValueAt(row, column);
                // Do something with the data...
                System.out.println("hi");
        });Thanks

Hi there - it took me a while to replicate the problem (I'm not going to post the whole program - too big) - basically it seems that it is only not working once I add data too the table, so I guess I am adding it incorrectly
If you run this and click the add button you will then see that it is not working

HT1222 hello i have a problem with my fingerprint id its not working anymore like before his not recognised my finger anymore why ?

hello i have a problem with my fingerprint id its not working anymore like before his not recognised my finger anymore why ?

I have had to periodically delete and re-enter my fingerprint. The last update (7.1) may have improved that. You can delete by going to Settings > Touch ID & Passcode, enter your passcode and then tap "Turn Passcode Off" and then go back to the same area, put a passcode back on and then a fingerprint.

A problem with a timer event sometimes not working

Guys...
I have this problem:
I have a child added to the stage eacg 5 seconds and if this child still on the stage after another 5 seconds, you go to the next frame...
My problem is that sometimes it does not work, meaning that you can have this child on the stage for ever and nothing will happen... but sometimes it does work properlly...
Is there any mistakes in my code or what should I do?
var miC4:Loader = new Loader();
miC4.load(new URLRequest("nivel1.jpg"));
addChild(background1);
background1.addChild(miC4);
if (!lives){var lives:int = 3;}
var enem1:Loader = new Loader();
enem1.load(new URLRequest("1enemigo.png"));
var enemy1Array:Array = new Array(enem1);
var t1:Timer=new Timer(5000,1);
var t2:Timer=new Timer(10500,1);
recycleEnemy();
function removeEnemy(){
           background1.removeChild(enem1);
           recycleEnemy();
function touchListener(event:MouseEvent){
    enem1.removeEventListener(MouseEvent.CLICK, touchListener);
    removeEnemy();
function recycleEnemy():void{
        enem1.x=(50 + Math.random() * (stage.stageWidth - 150));
        enem1.y=(50 + Math.random() * (stage.stageHeight + -100));
        t1.addEventListener(TimerEvent.TIMER, addEnemy);
        t1.start();
        t2.addEventListener(TimerEvent.TIMER, bang1);
        t2.start();
function addEnemy(e:TimerEvent):void {
        background1.addChild(enem1);
        enem1.addEventListener(MouseEvent.CLICK, touchListener);
        enemy1Array.push(enem1);
function bang1(e:TimerEvent):void {
    if(enem1.stage){
                lives--;
                if (lives >= 0) {
                    t1.stop();
                    t2.stop();
                    removeChild(background1);
                    gotoAndStop(5);
Thanks a lot!!!!

ok, so there are a number of issues.
the first error is enemy1Array contains two duplicate objects ~5 seconds after entering that frame. i'm not sure if that's a problem because i don't see where you're even using enemy1Array, but you should fix that error (if enemy1Array is used) or remove enemy1Array (if it's not used).
the next problem is you can call recycleEnemy more than once and re-add those timers. flash will probably protect yourself from the bad coding but you shouldn't count on it. when you call removeEnemy you should stop those timers and remove those listeners before re-adding another pair of listeners. or just reset the timers in removeEnemy and start them in recycleEnemy. there's no need to re-add those listeners more than once. they could be added in your if(!lives) conditional.
the next (and probably most important) error is your removeChild(background1) statement which fails to remove enem1. so, when you re-enter that frame you have an enem1 on-stage that you can't kill and can't even reference. remove it when you remove the background1.

Best.

I am having the same problem with my sound, it does not work with my games. I tried the info that was given below

I tried the suggestion for the sound, but it is not working. the sound will not play for my games, but it does play for all other Apps

As you don't say what suggestion it is that you've tried, I don't know whether you mean for having notifications muted, so you may already have tried the following.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

Problems with "find nearby missing photos", not working like it should in LR4

After I imported photos into LR4 I decided to split the event within the same folder creating 2 subfolders and proceeded to move the files within the finder. Went to LR4 and synchronized the folder but it didn't fix the file location on the missing files. So I tried finding individual files and checked the "Find nearby missing photos" but this doesn't seem to work like it did in LR3, because it won't find any nearby missing files even though they are right there new to each other in the same folder.
I don't want to dremove them and re-import because I have added ratings and I fear I would loose this info if I did that...

Your assumption that you would loose your ratings and develop settings is correct, if you would re-import.
Reimporting is never a good idea.
For the rest you have two alternatives: either you reconnect one image after another, or you undo on OS level what you did in the first place, then execute the move inside LR.
Depending on how many images you moved this could actually be the fastest route out.
"Find nearby missing photos" did not work reliably for me either in LR3. I have never found out when it did and when not, so I have preferred to learn how to perform any such operation inside LR.
Another valid question is why you do not use collections for your desired split , and leave the folders as they were.
According to my prejudice MAC users would not be as conservative in sticking to folder structures as Windows users..;-))
Once you master LR folders could be very unimportant storage buckets, as every angle for organizing your images would be covered by (smart) collections and keywords and other metadata.
Good luck, Cornelia

Problem with defaultCommand - buttons, links, etc not working

Hi,
I've used the defaultCommand attribute on a number of pages in an application, and have noticed a serious problem :
After hitting enter, if no navigation occurs (i.e. only PPR), nothing on the page works anymore - no buttons, links, etc.
Is this a known issue? If so, is there a way to fix this?
Also, if an inputTextField has a f:validateLongRange tag, and the user enters an invalid value (i.e. text, or something out of range), when enter is pressed the entire page disappears, and I'm left with only the validator's error message. I know I could work around this by performing my own validation, but that is less than ideal.
Any help would be greatly appreciated. Thanks

Hi,
it does reproduce and I filed a bug. The work around is not to use the "defaultCommand" property as it works when e.g clicking onto the button

Problem with multi take drum tracks not working with group selection editing

HI All
Ive recently tracked drums into using 7 mics and doing multiple takes layered on top of each other, the 7 takes belong to the same group and i have enabled group editing in the settings.
I think i changed the comp options at the end of the track and as a result audio tracks 1 and 2 edit between takes together fine. I.e. when i choose say take 5 with track it does the same selection for track 2.
Tracks 3-7 work in the same way fine, im just wondering if anyone knows how to get them as a complete group again so that when i choose take 5 for example on the one audio track, it will make the same selection for all of them!
thanks

Colin,
I did a multi camera edit of Act 1 of a taped performance and all went well. Moved on to Act 2, which ran longer and each camera needed a tape change. So I matched the clips from each camera on each video track and tried to move on to the sync & then create a multi camera sequence stage of the project. That's when I hit a road block. I could not sync the four video tracks. So I consulted Adobe's on line help and this was all I could find about my predicament:
Note: Adobe Premiere Pro uses an overlay edit when synchronizing clips. Take care not to overwrite adjacent clips if you have multiple clips on the same track.
So what was I to do next? I found your post and now know exactly what to do. Thanks for a great explaination and saving me a lot of head scratching.
Why couldn't Adobe explain it as well?
Thanks,
Angelo

Preloader problem with swf in different domains, not working online

Hello
I've an swf (loader.swf) hosted in dominioA.com, that justs loads a swf (movie.swf) hosted in dominioB.com.
loader.swf has a preloader. When I execute the movie in flash, it works perfect, but when I upload the swf, the preloader doesn't works. I see 0% and after starts movie.swf normally.
Here is the code of loader.swf
Security.allowDomain("www.dominioB.com");
Security.allowDomain("www.dominioA.com");
var contexto:LoaderContext = new LoaderContext();
contexto.applicationDomain = ApplicationDomain.currentDomain;
var _preloader:MovieClip=preloader

var _DOM:String="http://www.dominioB.com/movie.swf?anticache="+Math.random();
var myLoader:Loader=new Loader;
addChild(myLoader)
myLoader.contentLoaderInfo.addEventListener(Event.INIT, initHandler);
myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onLoadPogress);
myLoader.contentLoaderInfo.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);

function ioErrorHandler(e:IOErrorEvent):void {
function initHandler(e:Event):void {
Any idea??

movie.swf load perfect, and everything works. It doesn't seem to be a cross-domain issue.

Problems with iweb and safari - 'buttons' not working in safari/firefox...

Hello. Help! I've been using iweb for a while with no probs - but on trying to launch my most recent site I'm finding the navigation buttons (graphic images not text buttons) work fine in iweb on my mac, plus fine on a PC but only partially in safari/firefox browsers... see sarahgreen.me and you will see that none of them work on the home page. Is this some kind of bug? I was wondering if it is anything to do with there being too many objects on the page or something? They are fine on a PC.
Thanks for any ideas.
Sarah

In iWeb do Command-Shift-L to see the layout of the page.
The content in the Navigation layer is blocking the content of the Header layer. The body layer is empty.
Move ( +Use Command-drag+ ) EVERYTHING in the Navigation layer and EVERYTHING in the Header layer INTO the Body layer.
Put content where it belongs.

Has anybody had problems with the global settings panel not working?

I am on PC, Vista 64bit. updated to the new flash player and now flash player will not allow me to chage anything in the global settings panel. I need to allow third party content for editing wix sites and I cannot change any of the settings. I have uninstalled and reinstalled many times and nothing has helped.
My adobe reader also crashed and now will not load after uninstall. Very frustrating! Everythign worked fine before the update.
Any ideas?

To allow Flash Player settings, close all browser windows, then open Windows Explorer and type %APPDATA%\Adobe in the address bar. Delete the 'Flash Player' folder in there. Do the same in %APPDATA%\Macromedia
Regarding Adobe Reader, please post in that forum.
