• Throw the list "cannot access a property or method of an object. null reference" during the scrolling of the white spaces

  Follow these steps:

     import flash.display.Sprite;
  
      import qnx.fuse.ui.listClasses.List;
      import qnx.ui.data.DataProvider;
  
      [SWF(height="1024", width="600", frameRate="30", BackgroundColor="#000000")]
      public class test3 extends Sprite
      {
          public function test3()
          {
              var l:List = new List();
              l.dataProvider = new DataProvider([{label:1},{label:2}]);
              l.setPosition(200,200);
              l.width = 200;
              l.height = 200;
              addChild(l);
          }
      }
  

  And run the application.

  Point the finger just below the last line of the list, and then drag upward or downward.

  You get this:

  How I not imprison it? Is this a bug of the qnx.fuse.up.listClasses.List component?

  After typing this post, I went back to the SDK download page and noticed there is a new SDK available (as dated February 3, 2012) 2.0.0. I used the previous version dated SDK Date January 16, 2012.

  So I advanced and upgraded to the latest version of the SDK, and this error no longer occurs.

  It must have been a bug.

  So I solved (kind of) my problem... Kudos to me... ha!

• Error #1009: Cannot access a property or method of a null object

  Hi guys,.

  I'm developing a Flex 3 Application.

  I have an accordion, with two canvas:

  • first painting (by default the selected accordion one) contains an advanced data column in the grid (with a stream of XML data provider) that call the function, quot; clarity_itemClick (event) & quot; on an itemClick.
  • the second canvas contains a custom component (ClarityActionDetail.mxml)

  The function called on the itemClick is the following:

  private function showClarityDetail(event:ListEvent): void { }

  clarityAccordion.selectedChild = detailClarity;

  clarityDetail.dataClarity = event.itemRenderer.data;

  }

  clarityDetail is the id of my custom component and dataClarity is a this variable in my custom component.

  When I click on an element of my DataGrid for the first time, the debugger shows the following error:

  TypeError: Error #1009: cannot access a property or method of a null object reference.
  components::ClarityAllActions/showClarityDetail() [C:\workspaces\Clarity\TODO\flex_src\com ponents\ClarityAllActions.mxml:67]

  (Line 67 corresponds to & quot; clarityDetail.dataClarity = event.itemRenderer.data; & quot;)

  The second times I click on an element, the second accordion opens and the custom component is loaded with the correct data (= dataClarity).

  I don't know how the fix of this problem and any help would be greatly appreciated. Searching on the forums and how - to, to, I read on an on ADDED_TO_STAGE eventlistener, but fails to understand how to implement this in my code.

  
  Thank you

  Change creation strategy on the container parent to 'all '.  Default value creation strategy is not to create an item until it is necessary on the stage, so when you try to reference the custom component that is on the Web that has not yet been posted, it has not yet been created.

• When you try to selectIndex results in #1009: cannot access a property or method of a null object reference.

  I have a custom component that contains a list control. It has a data provider is a collection ArrayCollection from a web service.
  
  When a user adds a new item to this list, I want to roll to the index of the added item and highlight it.
  
  When I do this my mxml file I get
  
  #1009: cannot access a property or a method of a null object reference.
  
  Here is the code that produces the error: (navigator is the id of the custom component)
  
  currJob.jobComponents = ArrayCollection (ev.result);
  navigator.componentList = currJob.jobComponents; data provider for the list control being defined with the results of the Web Service call
  navigator.compList.selectedIndex = currJob.jobComponents.length - 1; This is the code that generates the error.
  
  Help!
  Thank you

  FIX: List is an accordion. I changed the creationpolicy for the accordion to "EVERYONE" and the reference to the work of control (list).

• External file ViewStack cannot access Script AS

  Hello
  
  I am very new to both Flexbuilder and Actionscript so I need help please. I have a main mxml file that contains a ViewStack as well as an external as file. The problem is that I use the files external mxml for the ViewStack that needs to call functions in the external IN the script file that is included in the main mxml. I am gettting compiler errors in these external mxml files (call to the method may be undefined) because they cannot access external FUNCTIONS because this file is included only in the main mxml.
  
  Everything worked great when I had all the code in a master file, but I'm trying to get a handle on separates the code AS code mxml as well as trying to use modules external mxml in the ViewStack. Can someone give me some advice how to separate everything and make it work successfully?
  
  Thanks in advance...

  You can use the import statement to import the class in the child's file, or
  you could broadcast an event that tells the parent to perform the function
  instead. Referring to the parent function is only a good idea if you want to
  to create a situation where the chld component only works in this same
  structure (couple).

• Cannot access page Plugin-based PDB (protein Data Base)

  OS: MacOS Yosemite 10.10.3. Cannot access the http://www.callutheran.edu/Academic_P.../lzipmast.htm Web page that uses a plugin of the PDB. I don't know if there are plugins for this format (s?), in FireFox, or anything else besides. Safari reports that "the sype file not specified", so maybe there is a mistake in the Web page itself (humor: "these biologists are sloppy with their microscopes to $5 million and more, but they don't know much about computers..")

  This page has not been modified since before that Firefox is a browser. There is probably a plugin for Internet Explorer v6 that will display that content. But you'll need a computer with Windows XP SP1 which is never updated Internet Explorer, and then find and install the plugin to make it work.

  You can download the file directly, if you want to try to find a program that will open its doors this: http://www.callutheran.edu/Academic_Programs/Departments/BioDev/omm/lzipper/pdbs/lzipdna1.pdb

• Facebook cannot access the photo library

  When I try (on a Macbook Pro) 'create album' or 'add photos' on the women's FB page, I can see, but cannot access its photo library.  Why?  I can, however, access the photos directory - unfortunately, uses Photo pictures are not stored there.   Apple told me that they no longer support iPhoto, but were instead switching to 'Photos '.  So that's where all the images are imported from the camera.  WTH?  It shouldn't be this difficult.

  The photo library of the system will be available from the sidebar of the selector Panel of file like this:
