Adobe’s finally come around with a spellcheck engine. Unfortunately in it’s beta stage, the UI classes require the Flex mx components, so if you’ve still not dived into the Flex framework, it’s up to you to build an interface for displaying misspelled words, and providing suggestions. On the bright side, they’ve included a binary english-dictionary, and
it’s really very easy to start adding realtime spellchecking using the SpellChecker, and SpellingDictionary classes.
