Flex3: Extend FormItem label to be multiline with some rules

I need extend Flex FormItem label to be multiline and with some rules I used this, but I need improve it. [login to view URL] rules: 1 next line in multiline must be shorter than previous It means that first line will be always most longer, second less and third more less 2 in one line cant be single word or char if happend that last line is single word or char, join it with word from before 3. end of line cannot end with "/" if some words is after it see on the attached picture code bust be nice and smart. Its very important! it must be in Flex SDK 3,6 I prefere someone who is able continue to extended (like another project) if I will need to add some more rules
