setData method

Implementation

    var value = options.isNotEmpty ? options[0].value : null;

    // set to first entry if no datasource
    if (datasource == null)

      // if we set value to itself it will cause an infinite loop
      if (this.value != value) this.value = value;
    }

    // set to first entry after data has been returned
    else if (options.isNotEmpty)
    {
      // if we set value to itself it will cause an infinite loop
      if (this.value != value) this.value = value;
    }
