How to refresh iterator to get the deleted item

Hi,
Scenario:
User loads the first page. He can see his profile details. He clicks on a edit link ; it opens a popup to edit details along with a save and cancel button. He deletes his phone number and click on cancel. The cancel button will just close the edit popup.
Problem:
He is not able to see his phone number in the front page. Only if he commits his phone number should get deleted. I think i have to clear the cache and refresh the iterator on click of cancel. I have added CacheResults="false" for iterator.
<iterator Binds="AdminVO1" RangeSize="25" DataControl="AppModuleDataControl"
id="AdminVO1Iterator" CacheResults="false"/>
I tried to refresh the iterator like iterator.setRefreshOption(8192);// as i found in one blog.
Its also not working. Can anyone please tell me how can i refresh the iterator to show the deleted row when he goes back to the first page on click of cancel

sorry for the post

How to refresh VO to get the changed value in other AM or backend database

i have tried to use executeQuery() ,but it does not work. now i always do a rollback method ,a bad idea.:)

Mind that ADF BC (probably like any other persistence framework) caches data. So when you update something in the database other than via ADF BC, you then have in the ADF BC cache what is called 'stale data'. When you try to commit that nevertheless, the database will tell ADF BC that the record in the database has been updated by another user, and a rollback will be done. That is all to be expected.
You can find some more info on how this works here:
http://download-uk.oracle.com/docs/html/B25947_01/bcvoeo007.htm
It also explains how to clear the cache and enforce that data will be read from the database.

How do I get my deleted emails to go to the deleted items in Outlook and not the archived folder?

How do I get my deleted emails to go to the deleted items in Outlook and not the archived folder?

Who is the email account provider?
With an Apple iCloud account, there is a preference setting with the account settings on the iPhone to archive messages - save deleted messages in your Archive folder.
I believe the same is available with a Gmail account.

How to get the selected items from listbox

Regarding listbox i have two questions
1) I want to get the selected items as per the order in which ihave selected.Presently i'm getting in the ascending order.For example after selcting the 1,2,6 if i select 3 then its giving 1,2,3,6.But i want it in the order 1,2,6,3
2)I want to select items from a single list box to many other listboxes.(ie) my first selection should goto first,second one to the second listbox and like this.How should i write the logic.
please give me a suggestion.

In order to have the selected items line up in accordance to the selection order, please do it one at a time. (That's the limit for that VI)
If you need more than that (i.e. to regconize which item clicked first and which one comes later), you may have to figure it out ya
Wish you good luck. Perhaps, someone else has a already made vi.
Cheers!

I just got iphone 5c and i am not happy with it. It uses to much data and i don't even know how. I can't get the ringtones i want for my contacts.I got it on my free upgrade but i want to take it back and get something else but where i got it they say i can't because i don't have the earbuds and i have serches or them. now i am suck with a phone i don't like at all until my next upgrade. this is very dishearten

1. If you are this unhappy with that phone, and the lost earbuds is the only thing stopping you from taking it back, why do not just buy some earbuds. That way you can get rid of that phone. It all depend upon how much you want to get rid of that phone.
2. Yet if you are stuck with that iPhone, here is something might help you to control the data usage. By design, iPhones do turn off WiFi when they go dormant. So if a download is in progress and so forth when the phone goes dormant, it will switch to use cellular data, if this setting is left on. Therefore, from multi-sources I have learned that if you keep your iPhone connected to a power source, then it will stay connected to the available WiFi.

How do I go about getting the product serial number to register my product as well as install my product. I bought it with a product box. On the software disc sleeve, there is a series of numbers pasted at the bottom of the sleeves but this is not valid

How do I go about getting the product serial number to register my product as well as install my product. I bought it with a product box. On the software disc sleeve, there is a series of numbers pasted at the bottom of the sleeves but this is not valid. When I tried to type this in for registration, it does register as this numbers also contain letters in it. Apparently the registration boxes accept numbers only. What do I do with a useless product for which I have paid good money for it?????

This is the simple solution which was offered to me when I tried to get the serial code on line.
The box and disc sleeve do not contain a series with 24 numbers which I presume is the product code to install.
I tried to redeem the registration code by following what they recommended, but inevitably it gets to the page that showed the registration boxes that need 24 serial numbers and I got stuck again.
This product is so different what my previous experiences of other software products where I just enter the serial number straight from the disc sleeve and then I got registered and go on to use the software.
I is really frustrating, spending the last two hours trying to get my product going....

Do any one know how much it is to get the new ipod touch with the camera if you trade in your old ipod touch?

Sounds like you need a new battery. I would make an appointment at the Genius Bar of an Apple store to confirm. Apple will replace the battery for $79. A third-party place like the folloing may be less expensive. Google for more places.

How to get the Clicked Item of a ListBox?

I need to get the clicked item of a listbox.
The item can be at first selected, when I click it again, it
automatically gets de-selected, but I want to get that item
whenever I click it. Any idea how to do this?
This line does not work, because it gets the selected item.
var pattern:String = event.currentTarget.selectedItem.myname;
This one must work,but something is missing.
Anyone can help me with this?
marks is my ArrayCollection;
var pattern:String =marks.getItemAt[??].myname;

Here is my code. Am using this function in the itemclick
event of the ListBox.
My ListBox is a multi-select listbox. So am selecting several
items by pressing "Ctrl" key and selecting each item using click.
Say I have selected 4 items, when I press "Ctrl" and
de-select one of the items, I want to get the itemname of the
deselected item.
public function createMarksList(event:ListEvent):void{
// Alert.show(new
String(event.currentTarget.selectedItem.myname));
// var pattern:String =
event.currentTarget.selectedItem.myname;
// pattern = pattern += "," + pattern;
// text1.text = pattern;
<mx:List x="9" y="46" width="121" height="121"
id="lstMarks" allowMultipleSelection="true"
itemClick="createMarksList(event)"></mx:List>
So, your help is required here buddy.

How can i do to get the picture on the projector?

When i connect my macbook with an vga adapter to my projector it does not work. The projector is saying: no signal. How can i do to get the picture on the projektor?
Thanks

Hi axel559,
Try connecting the MBP to the projector with the projector on, then boot the MBP, if it does not detect the projector, go to system perferences>displays>click detect displays. You might then have to adjust the resolution to have a correct image, usually 1024X768.
Hope this helps.

My ipod is the second Generation, how can i upgrade to get the latest game apps and such?

My ipod is the second Generation, how can i upgrade to get the latest game apps and such?

You probably can't. Many games and other apps now require iOS 4.3 or later, and iOS 4.2.1 is the last version that will run on a 2nd-gen iPod touch. If you want to run newer games, you'll need a newer iPod. If you want to look for games that will run on your iPod, here's a tip from another user that may help you:
"I was running into the same problem trying to find apps for my daughters Iphone 3g running 4.2.1. What I did was go to the Itunes store through Itunes on my PC, and then went to the bottom of the main page and clicked "Browse." On the browse page I selected, App Store, Games (category), Kids (subcategory), and then a list of apps appears below.
I sorted by date (oldest to newest) by right-clicking next to "price" and choosing "release date" on the menu that pops up. The date created field will then be showing, which you can click on to sort newest to oldest or oldest to newest. I downloaded a bunch of free apps starting from the oldest (by name - you don't have much else to go on). Of the 30 or so I added to my Itunes, about 27 of them were compatible with 4.2.1.
This is defintely not a perfect way of finding apps, but after spending a lot of time searching for a better way this was the best I could come up with."

Upon upgrading to Yosemite, the Pages and Numbers apps will not open (although they are the latest versions) and Keynote will not upgrade; how do I go about getting the apps to open?

Upon upgrading to Yosemite, the Pages and Numbers apps will not open (although they are the latest versions) and Keynote will not upgrade; how do I go about getting the apps to open? Is this a common issue?

Hi Madhattanite,
Welcome to the Support Communities! When did you purchase your Mac? The first thing I would suggest is to review the information in the resource below for the Up-To-Date Program for Pages, Numbers, and Keynote.
Once Yosemite is installed, you should have the option to Accept the Pages, Numbers and Keynote apps in the Mac App Store Purchases pane.
