    Help in binding data

    karoljouis Level 1
      In my project i have a component that gets data from the server and lists the task details. I have the following AS code and MXMl code to display a combobox for categories.

      private var taskCategories:ArrayCollection = new ArrayCollection([{label:"Morning",category_id:1},{label:"Evening",category_id:2}]);

      <mx:FormItem label="Category">
      <mx:ComboBox height="23" width="162" id="task_category" dataProvider="{taskCategories}"/>

      Using Flex Debugger i found a warning

      warning: unable to bind to property 'category_id' on class 'Object' (class is not an IEventDispatcher)

      Can anyone help on this issue. Thanks.

          The code you attached does not give me the warning in the debugger, but depending on how you use it, like if you use the data elements in a binding situation you might, because although the ArrayCollection uses binding, your data elements do not.

          If it is possible to provide a more complete, and yet still simplified, code example displaying the issue, we might be able to give more hints.
