warning: unable to bind to property

     <fx:XMLList id="nastavitve">
      <nastavitve>
       <zacetek omogocen="{p_zacet.selected}">
        <slika>{slika_i.text}</slika>

       </zacetek>
       <konec omogocen="{p_konc.selected}">
        <tockovanje>{tock.selected}</tockovanje>
        <kljuc>{kljuc.text}</kljuc>

Main application:

  </shramba>

</fx:Declarations>

Answer 1

Are you using the [Bindable] property in the parent control. Usually flex compiler will give 'Unable to bind to property' warning when the [Bindable] tag is not there.

If you are not using Bindable tag the binding may not happen correctly. We can't predict the binding process if that tag is missing. sometimes it will get bound, sometimes not. so first check whether the bindable tag is there or not
