This enumeric exists or have a similar in .AIR?
ActionScript (and consequently AIR) don't have a concept of "true" enumerations that are strongly typed like the ones in C#/.NET. Instead, in ActionScript when a property or a method parameter expects a predefined set of values, there's a corresponding "pseudo-enum" class like the FileMode class that only includes static constants, each of which represents one of the possible values.
But when I take the control of a file, in FileMode.READ and other app want to write something here, my app dont work. The same case happens when I take the control and the other app want to write something, the other app fails.
