Problem with Request for Permissions (mobile app)

In my application I want to publish the results of the games on facebook. I used this tutorial: http://www.adobe.com/devnet/facebook/articles/flex_fbgraph_pt1.html
Here is a fragment of my source code:
<fx:Script>
        <![CDATA[
            import com.facebook.graph.FacebookMobile;
            import mx.events.Request;
            import valueObjects.GlobalVariables;
            protected var extendedPermissions:Array = ["publish_stream","user_website","user_status","user_about_me"];
           protected function initApp():void
                FacebookMobile.init("app ID",loginHandler);
            protected function loginHandler(success:Object,fail:Object):void
                if(success){   
                    currentState="loggedin";
                    nameLbl.text=success.user.name;
                    userImg.source=FacebookMobile.getImageUrl(success.uid,"small");
                    birthdayLbl.text=success.user.birthday;
                    FacebookMobile.api("/me/statuses",getStatusHandler);
                else{   
                    this.login();
            protected function login():void
                FacebookMobile.login(loginHandler, stage, []);
            protected function logout():void
                FacebookMobile.logout();
                currentState="loggedout";
            protected function getStatusHandler(result:Object, fail:Object):void
                statusLbl.text=result[0].message;
            protected function submitPost():void
                FacebookMobile.api("/me/feed",submitPostHandler,{message:GlobalVariables.d.toString()}, "POST");
            protected function submitPostHandler(result:Object,fail:Object):void
                FacebookMobile.api("/me/statuses",getStatusHandler);
        ]]>
    </fx:Script>
I have problem with permissions. After login I see a white screen instead of request for permission.  The desktop application does not have a problem with it. When I log for the first time to the desktop application and I will give the permissions applications, then in the mobile application everything works fine. But this is not a good solution. And so please help.

The labelField of IconItemRenderer only supports single line text.  Try using the messageField instead:
<s:List width="200" height="200">
    <s:dataProvider>
        <s:ArrayList>
            <s:DataItem desc="1 Hello World Hello World Hello World" />
            <s:DataItem desc="2 Hello World Hello World Hello World" />
            <s:DataItem desc="3 Hello World Hello World Hello World" />
        </s:ArrayList>
    </s:dataProvider>
    <s:itemRenderer>
        <fx:Component>
            <s:IconItemRenderer labelField="" messageField="desc">
            </s:IconItemRenderer>
        </fx:Component>
    </s:itemRenderer>
</s:List>
If you need more control you might need to subclass, this post might help: http://flexponential.com/2011/08/21/adding-multiline-text-support-to-labelitemrenderer/

  • Problems with applet for displaying desktop app's output

    I inherited a desktop C++ (VC6) application that uses the user's web browser for output. When the system first wants to display output it writes a temporary html file, fires up the web browser with an html page with an applet that opens a socket that listens for messages on a particular port. The C++ app then sends the temp file name through the socket for the applet to display. When new output comes along the new file name gets sent through the socket and the applet updates the web page (so all of this work is just so that you don't get a new web page for each output). It uses a similar mechanism to display help (sending the relevant section number through the socket). The relevant Java looks something like this:
         m_serverSocket = new ServerSocket(m_theApp.m_port);
    and then later
         clientSocket = m_serverSocket.accept();
    Recently the Sun decided that connecting to localhost is a security risk (see http://sunsolve.sun.com/search/document.do?assetkey=1-66-246387-1), so that this accept() now throws a security exception. I'm trying to fix this but I'm not getting anywhere. Here are the things I've tried and decided doesn't work (feel free to point out mistakes or misunderstandings on my side, I'm a noob at java):
    1) I changed the C:\Program Files\Java\jre6\lib\security\java.policy file to add "accpet" for localhost:
              permission java.net.SocketPermission "localhost:1024-", "listen,accept";
    this works, but I can't use this because a) it isn't safe, b) we don't want users to have to change their java.policy files and obviously the installer can't do it
    for them.
    2) I don't want to sign the applet because this will be really confusing to users (why should they be asked to trust anything from a desktop app that doesn't even do
    anything over the net?)
    3) I've tried passing a command line parameter to the applet in order for it to use an "application" specific policy file, but it seems that an applet can't take
    the -Djava.security.policy command line parameter.
    4) I've read that unsigned applets can (only) open sockets back to the server from which it was loaded, but I'm not using a webserver so there is no server URL (and
    localhost doesn't work).
    I'm out of ideas but would love to hear some!

    Pay $150 or so to get your certificate signed by one of the major Certification Authorities. Signing your Jar will then stop the user being asked if he trusts the signer.

  • How to use OneDrive for Business mobile app with SharePoint 2013 on-premise?

    Hi All,
    I have a SharePoint 2013 (with latest December updates) that host a dedicated personal web site for users.
    The OneDrive portal works fine and users are able to sync their files with the OneDrive client for Windows.
    Now I want to test the OneDrive for Business mobile app on Android, but there is no option to specify the "personal" portal URL.
    It asks only for domain credentials.
    Does I need to configure specific records on my public DNS to allow mobile users to sync their files?
    Thanks

    I can confirm that with iOS you can connect to your SharePoint server through the advanced options.
    But the very strange thing is that the OneDrive version for Windows Phone 8.1 is limited as the Android version.
    This has no sense.
    Why does Microsoft should limit the Business functions on its mobile operating system, and not on iOS?
    Another strange thing is that configuring my Exchange account, Windows Phone 8.1 informed me that it has connected OneDrive for business (but is a fake information).
    See attached image.
    If I open the built-in OneDrive app, it give me the option to add a OneDrive for business account, but is only for Office 365 users (like with the Android version).
    I thing that Microsoft should let at least to Windows Phone users to connect to on-premise SharePoint sites.

    In SAP when ever we create any object(tables or MCDs) :
    there are two things CUSTOMER NAME SPACE(stored locally in that system only) and FORIEGN NAME SPACE(can be transported)
    CUSTOMER NAME SPACE objects starts with 'Z' or 'Y'
    FORIEGN NAME SPACE objects starts with any other digit other than 'Z' or 'Y'
    So youhave created MCD name CIBERNW which starts with 'C' (its not customer name space with z or y)
    so it will be stored in package(so that this package can be transported to any other system later)
    So what ever you have done is correct.
    You can create your own request also.
    But confirm once that whether you are supposed to store your MCD this that package.
    <b>
    can you please tell me this process is Right or wrong
    if it is wrong can you please tell me the right process
    and it will some default Requests which Request we need to select
    or we need to create the Request where we need to create that
    what is process we need to follow ?</b>
    So this is the concept of request.
    So this request is nothing but....
    When ever we create tables or MCDs we try to save it..so if we are trying to create objects in Foreign name space(i.e without 'Z' or 'Y' inthe beginning) so it will ask to create this object in a package which requires request(transport request)
    All objects are stored in package,( so this package contains many objects like MCD,SYNBOS etc what ever we store in it) so we can transport this package from one system to another system so to transport we need to generate a transport request for that package and them release that transport request.....
    So once the package is released and we try to edit or create new objects in that package it will ask for some new request.....
    Yes we can create our own request and later release it.
    But in your case u can take up the default request and continue.
    If this MCD is for only testing purpose(for our selfs)..means this MCD is just for our testing sake..its better to create it in Customer name space..starts with 'Z' or 'Y'.
    I hope its clear.
    Cheers,

  • Problems with Syncing to Lightroom Mobile

    I have the following problem with syncing to Lightroom Mobile:
    In Lightroom desktop it seems that the collections will be uploaded correctly (number of images is counting down to zero). Changes will also be uploaded.
    In the web interface I see the collections somtetimes and sometimes not. I can make them appear if I chose the "make collection public" in Lightrrom desktop.
    In the iOS App there is absolutely nothing happening: "There are no collections"

    Hello,
    I have a strange problem with Twitter for Mac. On both my home and office Macs. New posts appear in app window but there aren't any notifications even though notifications are set in preferences to show in both dock and menubar. Perhaps anyone noticed similar strange behaviour? I didn't find anything similar on Twitter forums.

  • Problems with Requests

              Hi,
              i am using weblogic in my project both as a webserver and as the application server.
              But i am facing problems with requests being sent to the server. Basically i have
              a form in my jsp which, if submitted by multiple clients at the same instant in
              time, the server gets confused and mixes up the data in the requests !! the form
              is submitted to another jsp which in turn calls a SLSB which in turn calls various
              entity Beans to fulfill the request.
              Now if 2 or more clients hit the submit button together, the server is mixing
              the data from the requestsand i get corrupted output as a result.
              That if i submit values (a,b,c) from one client machine and values (x,y,z) from
              another machine, the server puts one of the transactions properly and in the other
              it picks up the data from the other request and takes something like (x,y,c) !!
              Is this a bug in Weblogic 6.1 or am doing something wrong ?? Anyone faced this
              problem ?
              Any help would be appreciated.
              Raja
              

    Hi,
              It's highly unlikely that it's WebLogic. Somewhere along the line, you are
              calling or referring to the same instance of either a class of a variable.
              You should brush up on the meaning of static variables.
              Make sure that you are not using class-level variables in your servlet. WLS
              will create only one instance of a Servlet or JSP and invoke it from
              multiple threads (requests) unless it is declared as SingleThreadModel. (See
              the servlet spec).
              When you declare variables inside a method - they are defined on the stack -
              so they're safe from multiple threads since each thread has it's own stack.
              If you declare them in a class, they're on the heap, and are shared by
              multiple threads invoking that servlet-class instance.
              There is a workaround if you MUST use class-level variables (not a good idea
              in a servlet). You can declare your Servlet (or JSP) as SingleThreadModel.
              This is less desirable since it carries a performance hit. It's best to
              design around it - but you might try declaring this to see if it helps in
              the JSP...
              <%@ page isThreadSafe="false" %>
              Of course, if the threading issues I've discussed above are occurring
              elsewhere in your code, you'll have to design-around it. Like I say, check
              for static class variables. It's unlikely that your other code is invoking
              the same instances of other classes from multiple threads (unless those
              instances are servlet-class-variables - and your problem will be resolved by
              the above).
              Make sure that you are not referencing static variables in your servlet or
              other bean classes (unless you intend to). Static variables are scoped at
              the class level and are therefore shared by all instances of that class (or
              servlet). The above SingleThreadModel won't help you in that case since all
              instances of the same class will be using the same static variables.
              Hope that helps,
              Alex

  • Please Help?! Problems with Viber for iPhone 4s

    Please help!
    I have had problems with Viber for a while now and had given up! But now a few contacts only have viber and not other free messaging apps so I’m trying to use it again but still having problems.
    I have uninstalled and reinstalled a number of times and still have not received an access code. My main problem though is the messaging it would work fine and then I wouldn’t be able to send any messages and I would receive a message go into the app and the message would not appear.
    The other day I reinstalled it whilst at work and worked perfectly could send and receive messages easily. Then when I went home the problem stated again. I then uninstalled and reinstalled again and it worked perfectly, but now back at work I’m having the issues again! I can’t keep uninstalling and reinstalling is there a way this can be fixed?!
    If anyone is able to help me out it would be much appreciated! Thanks

    I did see mention of using Google Public DNS while I was searching the forums prior to posting, but to be honest didn't think it was a DNS-related problem.
    However, to rule it out I've set the prefered DNS servers on my router to Google's, but FaceTime still disconnects after 4-5 seconds when calling between me and my brother-in-law.  It doesn't matter who initiates the call.
    As a test, before I made the changes to my router, I logged into FaceTime as him on my MBP and tried calling myself on my iMac, and that was successful.
    The same test between the two iMacs when they were here was unsuccessful, so now I'm definitely thinking it's something on the '08 iMac.

    Problem with GarageBand for iOS 6/7 Iphone 3gs / 4
    Hello,
    On February 16, bought the GarageBand for iOS which was free and so I find and install it on my 3GS .
    Take the demo: Curtain Call Demo
    and within the instruments :
    audio Recorder
    Sampler
    Smart Drums
    Smart Strings
    Smart Bass
    Smart Keyboard
    Smart Guitar
    Keyboard
    Drums
    Guitar Amp
    1.4.1 is the latest version for ios 6.
    Configure my AppleID on a Iphone 4 and install the program , the version I have the Iphone 4 is the orange ( different from 3gs ) icon and put it on the AppStore : ios 2.0.1 for ios7.
    With these instruments :
    audio Recorder
    Sampler ( to download the instrument )
    Smart Drums ( to download the instrument )
    Smart Strings (Download the instrument )
    Smart Bass ( to download the instrument )
    Smart Keyboard ( to download the instrument )
    Smart Guitar
    Keyboard
    Drums
    Guitar Amp ( to download the instrument )
    and if I give what I need to restore tells me if I bought it I did not restore anything and tells me to buy :
    Complete collection of GarageBand instruments and sound at a price of : € 4.49
    As they are 2 different versions ? More than anything I say because I have to pay for the instruments in the 2.0.1 version of the Iphone 4 ... ?
    And besides not wearing demo Demo Curtain Call : (
    GarageBand 1.x If you are upgrading it using iTunes on a Mac or PC, you can restore the original collection of instruments and sounds. There is no need to buy this collection. Press "You've already purchased?" When displayed on iPhone, iPad or iPod touch.
    this puts on the AppStore but I have tried to restore as I wrote above, and does not work. There is nothing to restore.
    regards

    I've been having the same problem. However, I believe my problem is due to the 3G issues I've been having. I don't have internet access even when the 3G symbol appears, so probably my iphone keeps trying to connect to the network and has its battery drained! Have you been having the same issue?

    Here's the code that illustrates this problem.    Of particular concern is the July bar.    Because of the zero value data point problem, it's not possible to see the datatip for "aaa".
    Any ideas on how we can hide/remove the datatips for zero value data points ?        Thanks.
