This function writes the given text inText into a file created and saved on the device / PC, with the option to attach the file to the interview as an attachment. As the function is Asynchronous, when the file is actually written the callback function void OnWriteFileTextResult(String inFileName, bool inSuccess, bool inAppended)) is called and it includes the filename, success (read or not) and in this case the inAppended will be returned as false. You need to override it in your Advanced Scripts to perform what you need in case of failure.
