    XMList & TabBar

    3wl4k
      Hi,

      I'm using HTTPService to load tabs to my project and I have somethnig like that in data:XMLList

      <articles>
      <article>
      <id>1</id>
      <name>Article 1</name>
      </article>
      <article>
      <id>2</id>
      <name>Article 2</name>
      </article>
      </asticles>

      And I need to use it as dataprovider in TabBar, but
      <mx:TabBar dataProvider="{data}" labelField="name" />
      or
      <mx:TabBar>
      <mx:DataProvider>{data}{/mx:DataProvider}
      </mx:TabBar>

      (the same code works on DataGrid)

      THX

          What are you expecting each tab to be named?

          Article 1 | Article 2

          Like above? Then you probably want:
          <mx:TabBar dataProvider="{data.article}" labelField="name" />

          Hope that's what you're looking for:

            trace(data) shows that (data:XMLList):
            <article>
            <id>1</id>
            <name>Nazov clanku</name>
            <perex>0</perex>
            <creation_datetime>2007-06-17 19:41:05</creation_datetime>
            </article>
            <article>
            <id>2</id>
            <name>Nazov clankuNazov clankuNazov clanku</name>
            <perex>0</perex>
            <creation_datetime>2007-06-21 14:46:47</creation_datetime>
            </article>
            <article>
            <id>3</id>
            <name>Nic podstatne</name>
            <perex>rthbrxtgbnstrxhn xyxtykmxmjyzyjmnznfn</perex>
            <creation_datetime>2007-06-29 10:34:52</creation_datetime>
            </article>

            There's also problem with binding:
            1 Data binding will not be able to detect changes to XMLList "article", need an XML instance. Main.mxml

            And finaly there's one more problem, with equipment:
            Error: ERROR: The dataProvider of 'articles_categories' must not contain objects of type flash.display.DisplayObject.

            I would say, that the solution is to transform XMLList to array.... How to do that?

              The sollution of that problem was simple function:

              public var mainCategoriesList:XMLList();
              public vat MainCategories:Array();

              ...

              public function LoadCategories( ):void
              {
              MainCategories = new Array();
              articles_subcategories.selectedIndex = -1;
              for each( var data:Object in mainCategoriesList){
              MainCategories.push( {id:data.id, name:data.name});
              }
              }

              And the dataProvider in TabBar reffers to {MainCategories}... and it works.

              THX for all your help.

                Stick the attribute [Bindable] in front of your xml variable and there was a mistake in what i said

                should be:

                <mx:TabBar dataProvider="{data.article.name}" />

                then you don't need the function, just a little cleaner but at the end of the day, the same result so it doesn't really matter
