I am getting the following error, but if I dismiss and go on, my site works fine. Also, I am using almost identical code as what I am about to post in a separate section of the page for a different data grid, and that is not getting an error:

Error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

When I run in debug mode, i see the screen as it is in the attached image.

Here is the code for what I am doing ( cut out some of the stuff that is working fine to clean up what you are looking at):

I have looked through the code extensively and cannot see why getData is working and getDataExt seems to have an issue. Again, if I dismiss the error, the site is actually working fine! Thanks in advance for any help you can give me

Please include a 'snip' of the ExceptionReporting.mxml class, maily the lines that error.

If your app works otherwise, then do a try/catch on the method or action to avoid the error - then continue to debug. Because the data is based on a messaging system, be sure that all the variables are populating.
