I have tried...
Remeber FLex Builder is in 2.0 actual 1.0. There are a lot of rough spots
and design view is far from perfect.
There is no way to subclasss for stuff and keep the tricks going.
This is hardcoded into FlexBuilders code.
Would like to learn how to extend it though.
Peace, MIke

To the adobe developers,
I have found that I can extend the simpler display classes without much
issue, I have really only had issues with sub-classing the Form based
components. For our project (and probably many Flex projects) the form
concept is a strong one and the ability for designers to layout input
screens very quickly with Form, FormItem and FormHeader is fantastic. I
want to extend these classes primarily to preserve the integration with Flex
Builder. Maybe trying to make these classes infinitely extensible is the
incorrect approach. Maybe a tool that would allow me to integrate my
components more tightly in Flex Builder would be a better solution.
Specifically when someone drags an NForm on the page I want flex builder
to automatically wrap other components in an NFormItem etc.

No, that is not true. You know why? They didn't name it! That should be a
requirement of all composites Aodbe people.
You need to name every instance, this way if us devs do want access to it
we can get it.
EECOLOR, as far as the indicator, you would have to call getStyle(),
create the class instance, loop through all the rawChildren and do an is
comparison. This is just to get a reference, it sucks.
But, Is possible through that hack, I haven't tried it though.
