Data binding does not detect changes

During the passage of property that may be related to the function and assigning a new object data binding breaks
Take a look at the following example.

<? XML version = "1.0" encoding = "utf-8"? >
"" < mx:Application xmlns:mx = ' http://www.adobe.com/2006/mxml ' layout = "absolute" initialize = "init ()" >

< mx:VBox >
< mx:Text id = text = "{user.name"textbox"}" / > "
< mx:Button label = "Update user" click = "updateUser (user)" / > "
< mx:Button label = "Update User2" click = "updateUser2 ()" / > "
< / mx:VBox >
< mx:Script >
<! [CDATA]
[Bindable]
private var: user;

private function init (): void
{
User = new User();
User.Name = "first name";
}

private void updateUser(newUser:User):void
{
newUser = new User();
newUser.name = 'new name ';
}
private function updateUser2 (): void
{
User = new User();
User.Name = "new Name2";
}
[]] >
< / mx:Script >
< / mx:Application >

File User.as
package
{
[Bindable]
public class User
{
public var name: String;
}
}

Why the function updateUser break data binding?
The updateUser2 function works

Thanks for all replies ;)

Suggestion of levancho on sends an event seems good to me.

This could look like this:

var userEvent:UserEvent = new UserEvent ("new user", newUser);
dispatchEvent (userEvent);

Where UserEvent is an event with the new object.
Then all the elements that need this change pourraient, follow these steps:

addEventListener ("new user", userChanged);

private void userChanged(evt:UserEvent):void
{
evt. User; Update the link with the new user...
}

After looking more on the problem, I found:
Initially, the main problem was that the variable in the function will not update the refence sent in the function when you create a new instance, regardless of the use of data binding or not...

  • Data binding does not seem to work

    I have a report with 3 queries - a mother and two children. (In fact, there are more than 2 children, but only 2 of them are at the origin of the problem.) The current version of the report uses frames/repetition, overlapping frames and fields for each request of the child, which makes it almost impossible to change - and I need to change.

    I wrote a query that joins the two children in a single request. It works in SQL * more when I add the where clause that expected be added by data - links, but when I run the report I get the same results as when I run it in SQL * Plus without the data where a clause link. So it seems data links do not work for this game of parent/child of queries.

    No idea why? (Reports 6i)

    It is certain that data binding is the problem. I did the new 'child' an independent query, adding where clause to the query and deletion of data links between the parent and the child, and that is work - at least for the case where the parent returns a single record. I really need that data links work well, then re - asks the child for each parent. On the other hand, report editor showed a strange icon on the request of the child. It seemed to me the icon of data link with a slash through it--and he disappeared when I deleted the data bindings, so I'm sure that the icon showed that data links were not working. He didn't explain why.

    A quick thought - you define the columns in the datagrid manually, or they created dynamically during execution?

  • &amp; quot; data binding will not be able to detect assignments &amp; quot; warning

    new features in Flex Builder 3, Beta 2 (I did not have this problem with Beta 1), I have randomly (it seems) get warnings "data binding will not be able to detect assignments to < property >" for properties that are Bindable. If I run my AIR application while I have these warnings the app will not be able to detect assignments to these properties, as warning says. However do a rebuild/clean removes these warnings and my app then works well, with data binding works as expected. I have not found a way to force this behavior, it seems just occur occasionally during development.

    others have this problem?

  • CD drive does not detect in the EXSI vm servers

    Dear friends,
    We installed the server as virtual machine in the platform EXSI, CD player, but the server is not displayed. I tried almost all the options.
    Please help in this problem.

    The w player server is connecedt as a 'Customer' device and have "connected to power on" checked.

    We already install two server in this Exsi machine. Now when I created another virtual machine, CD does not work. And I checked also other server that also the CD does not work.

    If any server in this platform the CD drive does not detect. I think that some options in the EXSI platform that must change.

    Welcome to the community,

    the reason why physical disk is not detected could be a problem with the configuration server hardware, firmware on the CD-ROM drive...

    The easiest way to work around this problem is to use the ISO images and upload them to a new folder on a data store (for example ' ISO-Repository') using the browser of data store and then mount the ISO on the virtual CD drive. This installation of tracks also run a lot faster.

  • Does not detect the hdmi cable more (very specific scenario)

    Well then...

    Got a monitor 15-HD to hdmi cable and a mac laptop (13 in the retina).

    So when I got all that I put it all together and it worked. I left because there a little bit, everything is plugged in and did not return for some time, so my mac fell asleep at the time wherever I went. Disconnected everything to relax on the couch. I went back and all plugged together again except that now the mac does not detect the cable. Tried a bunch of things with it. Restart, unplug the unit, detection manually, etc...

    Since the monitor is used and recently purchased cable, I thought time to them to test first. Got a laptop PC and plugged into the cable. The monitor and cable worked.

    Tried to connect my mac to the TV with my ps4′s hdmi since I did that a lot before. Also works.

    The problem is literally the combination between the cable and the mac. Which is a problem since I got the reason was to serve as my mac.

    During my research, I saw that specifically leaving the connected hdmi where sleeps your laptop can spoil it supposed to be... I saw it one time so idk if it's true, but it happened to me... and no, it wasn't really a solution when I came across that. Tried Googling this specific problem, but did not meet anything since my problem seems so specific.

    Fast forward to the next day and tried again now that both had little respite between them. Plugged into the HDMI and my laptop starts fading and return to a black screen. The screen would go black usually and so the laptop screen and the monitor would appear once again. sauf_que this time that there not, he just kept it and the monitor has not changed (Yes) it's). Not wanting to let him do that too long I unplugged and tried a different port with an adapter, I have also, since I did 3 holes I could use this for might as well try them all again. But unfortunately, I don't have it trigger anything again. So I went through another round of troubleshooting to try to make it work, but here I am, trying to see if anyone else has had this problem and solved. I am back to wait another day I guess and just hope. If not idk what to do, except maybe to get another cable? I don't know if this would solve it well.

  • Cannot install Win 8 - Satellite Pro C660 does not detect HARD drive

    Hello

    My HARD drive died, so I decided to upgrade my Satellite Pro C660 - 1 9 to an SSD.
    I made a USB bootable with Win8 and starts very well.

    The problem is that it does not detect my SSD, so I can proceed with the installation.
    SSD appears in BIOS but not in Windows Installer.
    He said that there is a missing driver.

    I downloaded the AHCI drivers (XP, only ones available) and even in this case, after you have selected the only rider that appears, it says no new device found.

    I tried to change the SATA from AHCI mode to compatibility mode and it's the same thing...

    What can I do?

    Thanks for the help.
    Best regards
    Bruno Moreira

    More old Windows XP need a driver AHCI Intel's but I think this isn't a problem with SATA driver missing because as far as I know Windows 8 as well as Win 8.1 already contains the drivers to recognize the SSD or HARD disk drive.
    In addition, the installation of the OS should be possible even if the driver would be added for this procedure, you must use the "compatibility" mode
    As you say, the compatibility mode is not working too, so I think there is another problem.

    However, page driver Toshiba also provides a driver Intel RST (Intel Rapid Storage Technology) (Windows 8 - updated) you can try to add during the installation of the OS.

    But I m wondering if you would be able to install this Win 8 on common SATA HDD.
    Have you tried to format the SSD using a different computer, then install Win 8?
    Give it a try.

    any help?
    Thank you

    Hello

    You solved this problem?
    Could you install system 8.1 Windows on this SSD drive?

    I think that the installation of additional drivers during the setting procedure isn't necessary since Win 8.1 should already contain pilots essential.
    From my point of view of the few, there could be a compatibility issue (maybe the SSD firmware update could solve that problem).

    What another SSD disk usage? You have the same problem with other SSDS from other manufacturers?

    Your comments would be appreciated.

  • Designjet 110Plus NR: HP Designjet 110 Plus NR Maintenance Utility does not detect printer

    Hello

    I have a Designjet 110 Plus NR printer that prints, but when you use the maintenance utility, it does not detect printer. I downloaded the latest version H.06.0 and am able to install it. but when the search for the printer it will not find it, and I have no way to pinpoint it too my printer. I have the printer connected to my computer via the USB port on a docking station HP residing in my laptop (Elitebook 800 G1 win 7 pro x 64). Also, it is connected via a parallel to the NIC dongle to make it available on the network for everyone to print too so. All can print, I can print but the Cyan is not always print and before you buy new print heads, I would like to clean and align with the Maintenance Utility. I tried to use the printer in the dock station, plugging directly into the laptop and the network to connect, but won't find printer. I tried the alignment of the front that I found in other forums, and it did not work. Whenever I went to the printer, I uninstalled all drivers and and the computer and rebooted system maintenance utilities. I installed the drivers from the HP website, from the disc initially supplied with the printer and our network, still no change print server. Am still able to print but not to run diagnostics or alignments. I've scoured the forums HP and all the "recommended" patches have never someone who in fact confirms the
    'Fix' worked. Can someone help with this problem? It has been about 4 days that I'm looking into this and frankly it's kinda ridicolous saw that it's a plug-and-play printer. Thanks in advance for any advice you may have!

    Well, the network adapter has failed. I managed to install the software, but he gave a generic IP address of the printer and gave me the same mistake of not being able to communicate with the printer. So, I pulled up an old laptop XP downloaded the drivers from the HP site, rebooted, printed the test page with success and installed the system maintenance utility. And WHOLA, I saw the printer immediately in the USB of Maintenance section and was able to run the diagnostic page and determine our problem. Thanks again for your help Mike!

  • Satellite A500-19W does not detect battery

    Hello

    I have a portable Satellite A500-19W which is 6 months old.

    I bought this laptop while I was in Egypt and now I've moved (Dubai) UNITED Arab Emirates.

    Lately my laptop started suddenly does not detect battery.

    To remedy this that I have to remove the battery and clean the terminals then re - put the battery and turn it on and it's OK.

    This happened twice this week and caused my data loss because the charger is disconnected (if the charger is connected, the laptop computer continue to work, but the battery indicator does not light up)

    Now, my questions are the following
    1 - is this problem under warranty?
    2 - should I pay for anything when getting this laptop in service in Dubai noting that I bought in Egypt?
    3. is there a cure for this problem without going through the service center?

    Thank you

    1 / Yes. These questions should be covered by the warranty. Material is junk.

    2 / the nearest service contact and ask, but I'm sure you don't have to pay for the repair. The two countries are countries in EMEA, and avoid any kind of problems.

    3 / it is not much, you can do about it so please contact and explain the situation. They should check your laptop and find a reason why this happens.

    Don t waste your time and contact the closest service. If you have need for addresses and phone numbers you can find on http://eu.computers.toshiba-europe.com > support & downloads > find an ASP.
