This error message appears when there are problems in opening files associated with Adobe Flex applications (.mxml files). It usually happens when some nonstandard components are imported into the file. The error message means that the imported components are blocking the creation or population of certain text areas in the file, leading to it being inaccessible.
What the experts recommended
Unless you are familiar with Adobe programs like Flex, it is advisable to go to the Adobe website and use the Help / Support functions to get expert help in resolving the problem, which may involve removing some of the imported components. Unless this is done in the right way the file may become corrupted and all the data lost. However, if you are familiar with the program, you could try the following actions. Use the PopUp Manager option to display the components of the .mxml file that causes this error message to appear. Look at both the text areas in the file and load new identical data strings for both areas and then save and close the file. In most cases this will correct the problem and the 1009 error will not reappear.
