    Extended component cannot save data

    jfb00 Level 3

      Hi All,

      I am attaching an extended texInput component to allow only numbers and format the number with 2 decimals, also to manage the actual value in different option than text display.

      I can assign the value using text or realValue options.

      At the time of passing data from my extended component thru remote object it doesn't pass the data.

      <mx:method name="addNew" result="addNew_RO_Handler(event)">


      When I debug, I can see the value:  realValue = 6565 [0x19a5]

      In my method arguments shows as NaN.

      Any ideas?I am sure something simple is missing.
