Can't get Next/Previous Buttons to work

Hi,
I am trying to get the next/previous buttons to work on my jsp page. I have collected data from a resultset and stored it in an arrayList. My problem is that I am getting a null pointer exception when I try to display the jsp. I have a one to many relationship 1 company to many contracts and want to be able to go backwards and forwards through the contracts using the previous/next buttons. Any suggestions would be greatly appreciated. Below is my code:

Hi. I have purchased SBH20 but play, pause, next, previous buttons dont work. Volume buttons and play/pause button to accept/refuse calls work. I use it with connection with Xperia Z3. Can u help me what sould I do? Dont wanna withdraw. Thanks.

Yes, I did try with Xperia Z3 and it works fine for me. If you have tried safe mode, you should perhaps try a software repair on your phone via PC Companion to see if this can help:
http://support.sonymobile.com/global-en/tools/pc-companion/
In PC Companion you press start on Support Zone > Start on Update the phone/tablet software > Repair phone/tablet (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.
Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.

Thanks to everyone who helped on this. You are awesome. Especially Ned!! Posted here because I was unable to add more to the existing post.
Here is the question:
When you click on the reset button, this error below comes up. If you can't find the button it is the navy colored rectangular thing in the lower left corner of page.
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

When you click on the reset button, this error below comes up. If you can't find the button it is the navy colored rectangular thing in the lower left corner of page.
Here is the answer:
//when you click the reset button everything is removed from the stage
    //except the star, baclground, and reset button (trees and greeting REMOVED)
    public function onClear(Event:MouseEvent):void
            if (tree3) removeChild(tree3);
            if (tree2) removeChild(tree2);
            if (webText) removeChild(webText);
            if (tree) removeChild(tree);
            clickCount = 0;

This is the answer to what to put in the onclear function.

Well, if your Home button is broken, you won't be able to reset your phone, and if the Sleep/Wake button won't turn your phone on, it's a trip to the Apple store.

Sennheiser MM50s with iPhone - can't get the voice button to work :(

Can anybody advise?
I am on the latest iPhone OS. The headphones are brand new and sound great - but the voice/music control button does nothing but switch one speaker off while I hold it.
Any advice welcome. I've cleaned the earbud socket with surgical spirit and my original headset works perfectly.
Thanks.
Steve

Sorry if my answer confused.
I don't mean you need to use excessive force to push it home, but I do need to make sure the connector is all the way in and that it's easy to leave it nearly-but-not-quite home, and when that's the case the mic button doesn't work.
I've just tried quantifying it. From the front of the iPhone, when the headphones are all the way in there's no more than 0.5mm of gold connector showing. But with as little as 1.0mm showing, the mic button doesn't work, although sound does in both ears (and sometimes it's louder than normal too).
(Because of the curve on the iPhone, there's a good 1-2MM of connector showing at the back even when fully inserted)
If you're confident the connector is as far in as it'll go without damaging something, then it sounds like you've got either something in the connector slot of the iPhone or duff headphones. Do the buttons on the stock iPhone headphones work for you? That would narrow down the problem for you...
PS: you don't need to push-and-hold; that launches Voice Control. A short but confident stab should play/pause; two quick pushes will skip a track, and 3 quick ones will go back to the start of the current track or go to the previous track if you were already near the start. I found the button on the MM50s a bit un-ergonomic in position and operation to start with but I'm getting more confident with knowing I've hit it now. There can be a 1-2 second delay between hitting the button and getting an effect though.

Can't get the Submit button to work on Acrobat X

I was having this problem on Acrobat 9 and so I bit the bullet and upgraded, hoping the problem would go away, but it did not.
I have a simple form for an event which recipients will fill out and submit, emailing the entirePDF to others (not to me)
I've done these forms a zillion times, no problemo, but this is the first time I've tried since upgrading from Entourage email to Outlook, and I have a sneaking suspicion the problem lies there somehow.
Can install the button, all fine, but when I click it to test, I get this message:
"An error occured while trying to create a mail document. Acrobat is unable to complete your request."
Anybody know what I can do to fix this?
signed,
Desperate

I gave up on the 'Submit' button long ago, as have others, I suspect.
It fails in about half of the cases.
Now I place a note at the top of the form instructing users how to manually attach the form to an email in case the button doesn't work – it's ridiculous. Thinking about it, it would be more clean-cut to get rid of the button alltogether.
I also keep getting requests to provide forms as Word documents instead. Apparently people are way more comfortable with Word than willing to deal with idiosyncrasies in PDFs.

STILL can't get a simple button to work

Okay, I get this error message when I try to publish
settings:
**Error** Scene=Scene 1, layer=button, frame=1:Line 1: Mouse
events are permitted only for button instances
on (release) {
Total ActionScript Errors: 1 Reported Errors: 1
I thought I HAD created a button instance! I SO do not get
this. I did all the steps any tutorial talks about - and I took
your suggestions about putting in the scripting, i.e.:
on (release) {
getURL("
http://www.mypage.com/?from=tracking","_blank");
This is what I put when I opened up the actions window for
the button on frame 1 of Scene 1. Is this wrong? I'm seriously
about to have a heart attack - I need super explicit instructions
to understand, because if you leave out a step thinking it's so
obvious of course I would do it, that's definitely not the case.
:(

You have to make sure the button is selected so that this AS
code is actually connected to the button. If you want a different
method where the button isn't selected when you put in the AS code
then use this:
buttonInstanceName.onRelease = function() {
getUrl....
That way the code references the button's intance name and
doesn't need to be attached directly to the button, but rather the
frame containing it.
Please note that you can attach code to objects or the frames
containing them. Your code needs to be attached to the button. My
code needs to be attached to the frame. Get the difference?

Hello:
Thank you for responding so quickly.
I have added child and it has removed the error. However, the button icon has disappeared as you can see when you play the .swf and the reset button doesn't clear the stage of everything but the star and the back ground.

Xml gallery with thumbnails & next/previous buttons.

hallo all the wise people,
sorry to bother you, but i'm kind of desperate, and nobody around to ask, so....
i've spend now three full days editing an xml gallery... to my needs, and always goes messy, so maybe it's time give up and make my own from the scratch, or looking from a one closer to my needs =/ (helpless).
could anyone help - maybe any of you by some chance knows a link as close as possible to tutorial/source as3 fla to sthg as close as possible to this:
a) xml gallery
b) thumbnails
c) when thumbnail clicked a big picture shows
d) next/previous buttons possible
otherwise, i can also post the code of my gallery where i absolutely can't add next/previous buttons without making a big mess =/
i will be totally youbie doubie grateful for any help... any, if you only know any good link, 'll try to fugure out a tutorial or edit the source myself....
thanks in advance

heyyyo wise one,
at least this is really nice of you to ask - this gallery really makes me by now feel twice as blond as i am 8-0. but this is kinda really nested.
the xml structure goes like this (this is easy and more or, less standard)(Caption is neglectable, probabaly i will not even display it, unless i have some extra time):
<MenuItem>
         <picnum>01</picnum>
         <thumb>thumbs/Image00001.jpg</thumb>
         <picture>Image00001.jpg</picture>
   <Caption>Fist Title</Caption>
</MenuItem>
uaaha, then the as goes. there is the URLloader, but also two different loaders inside (one for the thumbnails, one for the big picture). and this is all inside a for each loop -eh... i was always trying to change the pictLdr behavior - the loader, that loads the big picture.
anyway the URL loader, and the main function, which is attached to it go like this:
var myXML:XML = new XML();
var XML_URL:String = "gallery_config.xml";
var myXMLURL:URLRequest = new URLRequest(XML_URL);
var myLoader:URLLoader = new URLLoader(myXMLURL);
myLoader.addEventListener("complete", xmlLoaded);
// Create the xmlLoaded function
function xmlLoaded(event:Event):void
// Place the xml data into the myXML object
    myXML = XML(myLoader.data);
    // Initialize and give var name to the new external XMLDocument
var xmlDoc:XMLDocument = new XMLDocument();
// Ignore spacing around nodes
    xmlDoc.ignoreWhite = true;
// Define a new name for the loaded XML that is the data in myLoader
    var menuXML:XML = XML(myLoader.data);
// Parse the XML data into a readable format
    xmlDoc.parseXML(menuXML.toXMLString());
    // Access the value of the "galleryFolder" node in our external XML file
for each (var galleryFolder:XML in myXML..galleryFolder)
   // Access the value of the "pagenum" node in our external XML file
           var galleryDir:String = galleryFolder.toString();
//trace (galleryDir);
//trace (galleryFolder);//output taki sam jak powyżej
// inicjuję variable flag, która bedzie trzsymac nazwę klikniętego thumbnail
var flag2:String = null;
// Set the index number of our loop, increments automatically
var i:Number = 0;
// Run the "for each" loop to iterate through all of the menu items listed in the external XML file
for each (var MenuItem:XML in myXML..MenuItem)
// Access the value of the "picnum" node in our external XML file
    var picnum:String = MenuItem.picnum.toString();
// Access the value of the "pagetext" node in our external XML file
    var Caption:String = MenuItem.Caption.toString();
// Access the value of the "thumb" node in our external XML file
    var thumb:String = MenuItem.thumb.toString();
// Access the value of the "pagepicture" node in our external XML file
    var picture:String = MenuItem.picture.toString();
// Just some trace I used for testing, tracing helps debug and fix errors
//trace(picnum);
var thumbLdr:Loader = new Loader();
    var thumbURLReq:URLRequest = new URLRequest(galleryDir + thumb);
    thumbLdr.load(thumbURLReq);
// Create MovieClip holder for each thumb
var thumb_mc = new MovieClip();
thumb_mc.addChild(thumbLdr);

// make button mode true and set it to invisible

clip_mc.alpha = .0;
     // The following four conditionals create the images where the images will live on stage
// by adjusting math through each row we make sure they are laid out good and not stacked
// all on top of one another, or spread out in one long row, we need 4 rows, so the math follows
if (picnum < "05")
       line1xpos = line1xpos + distance; // These lines place row 1 on stage
    clip_mc.x = line1xpos;
    clip_mc.y = yPlacement;

    clip_mc.y = 172;

    thumb_mc.y = 172;
   else if (picnum > "13" && picnum < "21")
   line4xpos = line4xpos + distance; // These lines place row 4 on stage
   clip_mc.x = line4xpos;
   clip_mc.y = 258;
   thumb_mc.x = line4xpos;
   thumb_mc.y = 258;
   // And now we create the pic loader for the larger images, and load it into "pictLdr"
   var pictLdr:Loader = new Loader();
   var pictURL:String = picture;
      var pictURLReq:URLRequest = new URLRequest(galleryDir + picture);
   //var pictURLReq:URLRequest = new URLRequest("gallery/Image00004.jpg");sprawia,ze zawsze wyswitla sie jeden obrazek
      pictLdr.load(pictURLReq);
   // Access the pic value and ready it for setting up the Click listener, and function
      clip_mc.clickToPic = pictLdr;
   // Access the text value and ready it for setting up the Click listener, and function
   clip_mc.clickToText = Caption;
   //var instName:String = flag();
   // Add the mouse event listener to the moviClip button for clicking
      clip_mc.addEventListener (MouseEvent.CLICK, clipClick);
      // Set the function for what happens when that button gets clicked
   function clipClick(e:Event):void
     // Populate the parent clip named frameSlide with all of the necessary data
     MovieClip(parent).frameSlide.gotoAndPlay("show"); // Makes it appear(slide down)
     MovieClip(parent).frameSlide.caption_txt.text = e.target.clickToText; // Adds the caption
     MovieClip(parent).frameSlide.frame_mc.addChild(e.target.clickToPic); // Adds the big pic
   } // This closes the "for each" loop
} // And this closes the xmlLoaded function
and the effect looks like this (it's a sketch, so big pictures are loaded randomly, don;t put too much attention to it): http://bangbangdesign.pl/xmlGallery/gallery29.swf
but i guess it's a terrible stuff to go through all this. i would be totallly satisfied with a likng to a good tutorial to do it from scratch, or just a hint where to start rebuilding this.
+ in any case i send greetinngs to whereever you are =]

How do I change default Next/Previous buttons?

When I automatically create multiple Submenus using the 'Create Chapter Index' command, Encore generates Next and Previous buttons.
These are rather plain - they seem to be the same style regardless of the style of menu selected - and I'd like to set another default style.
Can someone tell me how to do this, please?
Many thanks
John

You can build the next/previous buttons any way you like. Just put them on the menu and then specify them as "Next" or "Previous" under the type field in the properties box. There's more information about this in the help files under chapter menu automation.

How can i create an album with chose category list and next/previous button

hello guys im working on a project for my uni i finished the whole website but one thing is missing
i need to create a photo album with next and previous button, with choosing a category and inside each category i have like 5 pictures and i can change with the next/previous buttons to see another picture of the same category.
Please see the picture below to see what i mean.
some told me it needs flash but i dont know how to work on it :S so plz if anyone can help me
thank you

Dear Mr. Murphy,
thank you for your help.
Actually i have tried to search for a tutorial and i found that one that was very helpful and gave me the half solution. the part i found and it worked with me is the part of the next and previous buttons and moving from an image to another.
SO the part i still need is the list so when i click on a category i get the pictures of the chosen category, I had the idea of create a flash for each category alone and maybe i will be able to add them all together.
But i guess it's too much work and there must be a way where i can make it all in one flash file.
If you have any idea let me know please, thank you again for your help and i'm trying to search for the AS3 image gallery as you told me.
Regards

First/Previous/Next/Last buttons not working in Applications Master Detail

Jdeveloper version: fusiondrop5primeb26
accessed through appstta.oraclecorp.com
I attempted to create an Applications Master Detail UI by selecting Applications : Master Detail from the Applications Component Palette. I created the UI using my headers table (APPLCORE_SHIPMENT_HEADERS) as the master and the lines table (APPLCORE_SHIPMENT_LINES) as the detail. The master is shown as a form and the details are displayed as a table below. On the screen with the checkboxes to include First, Previous, Next, Last buttons, I checked all of them.
On the backend, my headers table has two rows.
When I ran the page:
1. When the page comes up, it shows the data for shipment header 1 and the associated details in the table below. This is correct.
2. However, the First and Previous buttons are enabled at the top. They should not be enabled since I am on the first record, and there is no previous record. This is incorrect.
3. When I click Next, the data does not update to the the next header record (shipment header 2). The data is still for shipment header 1. This is incorrect.
4. When I click Next once more, an Error window pops up:
Messages for this page are listed below.
ShipmentLineId Error java.lang.NullPointerException
ShipmentHeaderId Error java.lang.NullPointerException
LineNumber Error java.lang.NullPointerException
ItemName Error java.lang.NullPointerException
(same error is shown for all other columns in the lines table)
I was under the impression that we do not need to do anything special for the First/Previous/Next/Last buttons to work, other than checking the boxes in the page creation process.
The application in question is here:
/home/sheyu/jdevhome/descflexdemo/.
The ui project specifically is in this folder:
/home/sheyu/jdevhome/descflexdemo/mywork/descflexdemo/ui/
I have tried to start from scratch several times to no avail. Please advise.
Thanks,
Sherry
