I have built an interface in Flash CS3 and now have the need
to port it over to Flex. I am trying to do it with as little
re-build as possible, so I need to port the Flash components over
with it. I exported a SWC with all of the components I am using,
and added it to the Library Path of an AS project.
The build gives me no errors, but I do get a #2007 at
runtime. The error seems to be stemming from a Yahoo ASTRA Flash
component, which was included in the SWC.
TypeError: Error #2007: Parameter child must be non-null.
I have been searching around the net, and the majority of
people are saying that this happens when the skins aren't included
(so you need to set them before the component is added to the
stage). I am using customized programmatic skins, for which the
source files are included in the build, and the styles get set
before the component is added to the stage (I actually replaced the
default ones in the class).
Does anyone have any other ideas as to how I could fix this?
PS - It is an ASTRA TabBar component that is giving me
issues. I know that Flex has a TabBar and TabNavigator, but I can't
find any documentation on how to use these from an AS project (no
MXML). I will simply rebuild using the native Flex controls if
necessary, and if possible, but would prefer to fix the issue as it
currently stands. (I might go back to Flash at some point, and
don't want to tie myself to a particular solution, considering I
can't use Flex components in Flash).
PPS - If you are wondering why I am porting to Flex right
now, especially if I am considering taking it back to Flash in the
future, it is because I have the need to begin building in
FlashPlayer 10 functionality, and the only way you can build to
FP10 right now (as its in beta) is with a nightly build of
