DropDownList does not work in a new window

In this code, I create a new window when I click on the button. In the new window are the DropDownList and TextInput components. When the new window opens, click on the DropDownList control is no nothing - be it clicking a second time round to get it to open. However, click in the TextInput field first and then try to open the DropDownList control works without problem.

Any reason, why this happens? Is this a bug or something I am doing wrong? This problem occurs with 4.1 Flex and Flex Hero (version Sept 2010).

Is the code below, or download the FXP here.

// DropDownTest.mxml (application)
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" 
                       xmlns:s="library://ns.adobe.com/flex/spark" 
                       xmlns:mx="library://ns.adobe.com/flex/mx"
                       width="400" height="300">
    <fx:Script>
        <![CDATA[
            private function newWindow():void
            {
                this.close();
                
                var w:MyWindow = new MyWindow();
                w.open();
            }
        ]]>
    </fx:Script>
    <s:Button label="New Window" click="newWindow()"/>
</s:WindowedApplication>


// MyWindow.mxml (component)
<?xml version="1.0" encoding="utf-8"?>
<s:Window xmlns:fx="http://ns.adobe.com/mxml/2009" 
            xmlns:s="library://ns.adobe.com/flex/spark" 
            xmlns:mx="library://ns.adobe.com/flex/mx"
            width="400" height="300">
     <s:TextInput/>
     <s:DropDownList y="30"/>
</s:Window>

Can you please file a bug in http://bugs.adobe.com/jira

A workaround is to call this after w.open ();

w.setFocus ();

  • GADMEI USB TV Tuner card does not work on the new Windows 7 computer

    Original title: usb tv card is not supported in windows 7 x 64

    Hello

    I have new office... everything works fine, the problem is with my tv usb card.

    I tried gadmei model utv882e and utv332e... no one works with my office... but in my laptop with the same version of windows, two tv cards works very well.

    I have no other problems in my pc or tv... cards all drivers are up to date.

    Here is my desktop specs:

    model of motherboard is asus b85m-k

    Hello Faysal,

    Thank you for visiting Microsoft Community.

    As described in the question, I understand that your two cards of Gadmei USB TV Tuner does not work on your Windows 7 desktop. The same card works fine on another computer in Windows 7 with the same configuration.

    I would be grateful if you can provide us with the following information to help us better understand the issue.

    1. What happens when you plug-in card TV Tuner? Your computer will detect the device? Do you have a code or a message when it fails to connect?
    2. Did you check connecting them via a different USB port?

    There may be a possibility that drivers for Gadmei TV sticks are not correctly installed on the computer. We will try these methods below and check if that helps.

    Method 1:

    First of all, I suggest you to run the following Microsoft Fixit to get the problem diagnosed and fixed automatically.

    Hardware devices do not work or are not detected in Windows

    http://Support2.Microsoft.com/mats/hardware_device_problems?WA=wsignin1.0

    Method 2:

    If the fixit above does not resolve the problem, I suggest to download the best compatible driver on the device manufacturer (Gadmei) site or contact Gadmei to get the best driver for your computer and install it.

    You can also read the article below to help update the device driver.

    Updated a hardware driver that is not working properly
    http://Windows.Microsoft.com/en-in/Windows7/update-a-driver-for-hardware-that-isn ' t-work correctly

    I hope this helps. Please let us know the results. Do not hesitate to write back for any further assistance with Windows, we will be happy to help you.

  • Family safety does not work on a new laptop with windows 8 preinstalled

    Hello, I previously used Family Safety (FS) on my daughters netbook and it worked very well. I took my cell phone account that she does not have an account on. So for Christmas we he bought a new laptop (win8) of full size. I created myself as the admin, and him as a standard user with a different username than its netbook, and I configured FS for the new account on the new laptop. Well, I am not sure if more FS works on the netbook, but I am sure that it does not work on the new laptop to 100%. I tried over and over reconfiguring, sometimes it won't save even my applications updated. It simply doesn't get it. The only thing I can think is that, in the implementation of his account, it doesn't have an e-mail address, and I was forced to create a local account. Could it done than the FS functionality?

    Hi, I had family security to work by removing the local account that I wanted to monitor and adjust it upward with a hotmail instead of just local account. Family safety has started working immediately and exactly as expected. I always think that theres a problem when people are trying to implement local accounts. Thank you for trying to help me in any case, if I need help in the future I will contact you guys once again.

    iCloud music library has worked between my Mac, iPhone 6 and iPad Pro. However, it does not work on my new iPhone 7.

    When I try turn it off and on again, I do not get the merge or replace guest library that every site seems to say that I see.

  • Acorn TV does not work on the new Apple TV

    So disappointed that the Acorn TV app does not work with the new Apple TV we just bought. We have subscribed on iTunes and nothing happens when you try to activate the software. We can look good on the MacBook, iPad and iPhone. Verified the purchase on iTunes account and that's fine. Contact Acorn and say it is a matter of Apple.

    Strange that I have to use Chrome to even write this question. Safari and hers do not work with the Support pages. I'll send in the comments.

    I'm resetting Apple TV now. We have been with the Apple TV since version 1. I hope that we can make this work!

  • Shortcut Ctrl C does not work in the main window of Firefox

    I use Firefox version 38.0.5, Windows 7
    Since the update Ctrl + C shortcut does not work in the main window of Firefox. (I can't copy text from any website using Ctrl + C).

    Click right and using the copy in the menu works perfectly. CTRL V and Ctrl X work fine without problem.

    Ctrl C works fine when copying text from the address bar and search bar, I just can't copy anything from anything in the main window of firefox.

    I tried to run Firefox in safe mode, I have also reset firefox and a virus scanner, but nothing has solved the problem.

    If anyone has any suggestions, that would be great. Thank you

  • Re: NB200-134 - touch FN does not work after upgrade to Windows 7 Ultimate

    My NB200-134 of FN keys does not work after upgrade from Windows 7 starter to Windows 7 ultimate. I tried to install all the drivers found on the Web from Toshiba website for my lappy but it still does not work.

    Help please

    Hi asalamk,

    The FN keys are controlled by value added and Flash Cards Support utility package. I think you forgot to install these tools

    You should recheck the Toshiba page and download these two tools. Start with the installation of the package of added value, and then restart your laptop. After this utility installation of Support Flash Cards. Reboot once again and all the FN buttons should now work correctly.
