Hello
On your ResultEvent method you can add something like this:
private function onResultEvent(event:ResultEvent) : void
     yourBindableList = null;
     yourBindableList = event.result as ArrayCollection();
In this code i send to my BindableList a null value before i setter to list the result of my HTTPService, making a cast to ArrayCollection.

  • How to delete the existing list and prevent auto-completed web sites?

    Hi, As soon as I start to type "www" in the address bar, a list of previously visited web sites appears, as if auto-completed. They seem rather random, and not necessarily the most recent ones. I have tried resetting Safari, deleting the cache, looking these sites up in the various plist folders in the Library, using Safari in Private mode, etc. but it still happens. I find it a nuisance.
    How do I delete the existing sites, and how do I prevent more from appearing in the future?
    Thanks,
    Richard

    HI,
    Go to Safari/Preferences - AutoFill
    Click where it says: Edit
    You can Remove All or edit which url's you don't want.

  • How to delete the existing webservice?

    Hi,
    I have created a RFC function module and made it as webservice. Later I made few changes to the function module and exposed as new webservice. Now I want to delete the old webservice or deactivate the old webservice. How can I do it ? or is there any way that if I do any changes to the RFC function module it will also reflect the changes to the webservice?

  • How to delete the files from iPhone before selling?

    How do I delete the files from my old iPhone4 before selling?

    Hey adhot,
    Before selling your iPhone, you'll want to follow these directions:
    Before you sell or give away your iOS device, make sure that you have removed all of your personal information. Follow these steps to protect your data and get your device to its factory default state for the new owner:
    Back up your device.
    Go to Settings > General > Reset, then tap Erase All Content and Settings.
    This will completely erase your device and turn off iCloud, iMessage, FaceTime, Game Center, and other services.
    If you are using iOS 7 and have Find My iPhone turned on, your Apple ID and password will be required. After you provide your password, the device will be erased and removed from your account so that the next owner can activate it.
    Contact your carrier for guidance on transferring service to the new owner.
    When the device is turned on for the first time by the new owner, Setup Assistant will guide them through the setup process.
    Important: Do not manually delete contacts, calendars, reminders, documents, photo streams, or any other iCloud data while signed in to your iCloud account, or the content will also be deleted from the iCloud servers and all of your iCloud devices.

    How to use "me98" to delete PO from system completely?
    I am using "me98"(archive) to delete a PO that have a mistake for vendor code. 
    The following step is: 
    the 1 step: I maintained and saved a variant.  For this variant, I have to create a name for this variant and select the PO which want to delete. it's right? 
    the 2 step: I maintained a "Start Date".  For "Start Date",I select the "immediate " to execute it.  Is it right? 
    the 3 step: whether I maintained the "Spool Params" or not?  May I execute it immediately or not? 
    I have no idea for deleting PO via the "archive".   How can i do that ? 
    Archiving is not deleting. What do you think why SAP developed that much programs to retrieve and read data from an archive. 
    Archiving is saving and keeping data for a certain period (based on local laws for data retention and auditing purposes) outside of the production data base.  Such a job is usually done to keep the database small and fast. 
    While doing archiving the records are written to a file and verified to be readable and then the original record gets deleted from the database. Only if you delete then the file with the archived data you have deleted the record forever. 
    Sometimes people seems to work like a burglar and want erase every single evidence for an error. But even errors, or especially errors are subject to be audited if they are corrected in the right way. This is the same for financial and tax auditiors as for auditors for ISO 9000. 
    To be able to archive, you need to setup the path from SAP to the archive. You need to define the size of your archive and how may records should be kept there. 
    Step 1: Create variant for Archiving. Give it a name. Enter your PO number. Flag One step procedure. Flag detailed log. Erase flag for test run. 
    Step 2: Maintain your start date, you can use Immediate in such a small case. 
    Step 3: Maintain spool parameters. Enter your printer and set the values if you want to print immediatly and if you want keep the print. I suggest to hold the spool in the system. This helps you to determine any error. 
    Step 4. Execute the variant. 
    It creates 4 jobs: 
    ARV_MM_EKKO_SUB...., ARV_MM_EKKO_WRI.... ARV_MM_EKKO_DEL..... 
    ARV_MM_EKKO_STO.... If one of the steps fails, then everything is rolled back, hence nothing is archived, the record is still in your database. In this case use the jobs spool and joblogs to find out what happend.

  • How to delete the queries in  BW Production which are no longer existing.

    Hi,
    How to  delete the queries in BW production which are no longer existing in DEV.
    1. I tried Using RSZDELETE in Production it is not getting deleted and the below message given.
    Query object 4A7V83T3RB4ABIOKSDJT2HWDL is blocked. Deletion has been cancelled.
    2. I tried creating another query in dev with the same technical name and send a transport with deletion
    it is not working.
    Please advise me on this for any function module or any other method.
    Thanks
    Surya

    Hi,
    If you transported the query from DEV and now you want to delete it, you should open a BEx request (Dev Class under which it was originally transported -- or-- Standard - type) in DEV delete the query and move the transport to Production.
    As far as your error is concerned, usually  when you  can delete a query using the delete option in query designer itself,
    Business Explorer> query-> delete objects , when you press execute the system offers you a list of dependent objects on the query(workbook,views), in case the sysytem is unable to delete them i.e.they being used as a input query for a characteristic variable (replacement path),then system throws this error.You can delete these all depndents under there prescribed roles , fav s & then proceed.
    Hope this will be expedite.
    Thax & regards.

  • How to delete the orphaned Expected Rule Entries exist in the FIM portal

    Hi,
    How to delete the orphaned Expected Rule Entries exist in the FIM portal.
    A large number of orphaned Expected Rule Entries exist in the FIM portal (originally 140000k+ objects, currently 75000+ objects). They consume the a lot of FIM database space and slows down the identity lifecycle management synchronization processes.

    Hello,
    in my environments i use this approach:
    https://social.technet.microsoft.com/Forums/en-US/1af6cf77-4c55-4a3e-93cc-0baae80bc88f/expiration-workflow-cannot-delete-ere?forum=ilm2
    This sets up a compination of Sets, Workflow and MPR to let the "Expiration Workflow" delete EREs as soon as they get orphaned.
    This works fine since 3 years now, even if there are comming SQL-Jobs within a FIM update, but I implemented this before this was done.
    I would suggest to clear the current orphaned EREs with PowerShell to avoid request flooding when implementing the above solution. Then implement that housecleening above.

    Hi deva,
    write a class which implemets these methods
    CLASS lcl_event_receiver DEFINITION.
      PUBLIC SECTION.
        METHODS:
    To handle the toolbar on alv
         handle_toolbar
           FOR EVENT toolbar OF cl_gui_alv_grid
              IMPORTING e_object e_interactive,
    To handle the buttons on the alv grid
         handle_user_command
           FOR EVENT user_command OF cl_gui_alv_grid
           IMPORTING e_ucomm.
    endclass.
    Now Implement these methods.
    CLASS lcl_event_receiver IMPLEMENTATION.
    To handle the toolbar on alv
      METHOD handle_toolbar.
       DATA ls_toolbar  TYPE stb_button.
        CLEAR gs_toolbar.
        MOVE 3 TO gs_toolbar-butn_type.
        APPEND gs_toolbar TO e_object->mt_toolbar.
        CLEAR gs_toolbar.
        PERFORM icon_create USING 'ICON_INSERT_ROW' gs_toolbar-icon.
        MOVE text-010 TO gs_toolbar-function.
        MOVE text-012 TO gs_toolbar-quickinfo.
        MOVE ' ' TO gs_toolbar-disabled.
        APPEND gs_toolbar TO e_object->mt_toolbar.
        CLEAR gs_toolbar.
        PERFORM icon_create USING 'ICON_DELETE_ROW' gs_toolbar-icon.
        MOVE text-011 TO gs_toolbar-function.
        MOVE text-013 TO gs_toolbar-quickinfo.
        MOVE ' ' TO gs_toolbar-disabled.
        APPEND gs_toolbar TO e_object->mt_toolbar.
      ENDMETHOD.
       METHOD handle_user_command.
    In this form, check the function code(e_ucomm has the function code), based on that do the required action.
    as i said yesterday(i.e for appending a row, deleting a row, modifying a row)
        PERFORM user_command USING e_ucomm.
      ENDMETHOD
    endclass.
    Before calling the alv method, create a object of this class.
    DATA :
          gref_event_receiver  TYPE REF TO lcl_event_receiver,
          gv_tables_alv          TYPE REF TO cl_gui_alv_grid.
          CREATE OBJECT gref_event_receiver.
          SET HANDLER   gref_event_receiver->handle_user_command
                        FOR gv_tables_alv.
          SET HANDLER   gref_event_receiver->handle_toolbar
                        FOR gv_tables_alv.
    check this program for event handling, it is the similar way

    Hope u understood this.

  • How to delete the number saved in CALL FORWARDING list?

    how to delete the number saved in CALL FORWARDING list? seems like the number cannot be deleted in CALL FORWARDING list, i tried several times...
    he thing is, here are three numbers in the call forwarding list, one of them were set up by mistake, and none of them can be deleted.......it brothers me all the time. i already turn it off, but the number list is still there...

    Hello dennis130915 and welcome to the BlackBerry Support Community Forums.
    The image you have uploaded is unable to be displayed.
    Call Forwarding is a carrier controlled feature. Most likely, the number you see could be for the Voice Mail server.
    It's advised you call your mobile service provider to further assist with this feature.
    Thanks!

  • How can I delete the reading list in Safari on iPad 2?

    I would like to delete the reading list in Safari on my iPad 2. How do I have to do it?

    You can't delete the reading list portion of the bookmarks window. It is built into the app so you can't delete it. That is not optional.
    You can delete items from the reading list by swiping Across the item in the reading list to bring up a red Delete button. Then tap that button to delete the item from the list.

  • How to delete the values from TKOMV at runtime after creating PO

    Hi Padma
    Can you do this activity once the company code is in to production. I guess you can not do this activity, if the company code is already in to live. Setting or resetting of the recon accounts will hinder the previous actitivity. Infact resetting of the company code is also not a good option.
    Any how, thanks for the inputs. Please let me know whether i can do this activity only at the subledger level which will not impact other modules. The one solution i can figured out is , reverse all the transactions for the corresponding asset in the year of takeover and pass the entries again in the same year correctly which will have effect in Subledger and also in general ledger. But the business people will not allow this, since for a big client it will require lot of authorizations and approvals. Infact the vendor also, is cleared. So we have to reverse the cleared documents as well which is again a task and require approvals as well.
    Thanks and regards
