Flex Errors #2000 and #2035

If you run either of these errors the following problem may be the cause…

I ran into this problem when using the htmlText property and inadvertently not encoding some HTML (including a reference to a non-existent image src) under certain conditions.  I was not expecting the encoding to be the issue so I’d been looking at some of the other code that had changed recently.

One confusing aspect about this was that I initially got the #2000 error that was accompanied by the “Security Error: Error #2000: No active security context” text.  This error wasn’t very helpful.  Then I discovered that a different browser gave me the “Error #2044: Unhandled IOErrorEvent: text=Error #2035: URL Not Found” error.  This error was much more helpful.  Why the different errors from different browsers?!  Different Flash plugin versions!  The #2000 error was produced by 10.2 while the more helpful error was generated by 10.3.

Hope someone finds this useful.
