Flex 4 scrollers

Hi Guys,

I have couple of questions one particularly with Flex 4 and the other one is generally with flex,

1) The scrollbar's(V & H) in flex 3 are normally within the container itself and we get them when it normally overflows. But i guess in Flex 4 spark components we need to explicitly set them and manage accordingly. Is there any better or clear way of dealing with these also i could not find much about this anywhere?

2) Action Message Format (AMF) being a binary protocol which can be understood by flash runtime, How we can claim that our data is completely secure surpassing (if any possible)swf/amf interceptors/decompilers in the way?

In regard to your first question, the VScroller and HScroller components will automate the adding of scrollbars for you like most Flex 3 containers did. The reason you probably haven't seen much on this is because I think those containers were added fairly late during the Flex 4 beta.

In regard to your second question, AMF is secure as long as (and only if) you are communicating over https. In other words, if you have an SSL for domain xyz.com and provided that you load the flash or flex app with https://xyz.com, the AMF messages will be just as hard (or easy, depending on how you look at it) to intercept and decrypt as any other type of request.

Thanks Dan, i get your point for the second one and can you be more clear with the automating part for answer 1. Looking forward for your recent book release as the table of contents has some interesting ones..

Currently i face an issue in one my recent AIR application(am fairly new to Flex4), i am positioning many widget(separate components) each has self populated contents and functioning without any dependency on the other. since all of these different sized widgets are positioned in a main application, i gave the scrollers to the file and positioned these widgets within them having relative positioning for each. but yet when my application is resized or viewed in a different resolution, sometimes some of the contents in the widgets are cut though i can see the scrollers for the main file when it crossed its limit.. It would be helpful if you provide your explanation addressing with this case..

Thanks a lot in advance..
