Subject Re: [FlexJS] Guidelines for implementation of layout containers and navigation containers
Date Thu, 28 Sep 2017 20:29:05 GMT
Nicolas,

Fully understand your needs. Thanks for a deeper explanation. One of the
things which you can get out of the box is for sure that your business
logic free from Flash dependency in your app can be just used. Compiler
should nicely consume it and give you an JS.

The problem with FlexJS is that once someone is touching it he expects that
it will be working as good as Flex, but the true is that we have still a
lot of job to do and framework is in beta state. It means that we sometimes
need helps from someone who have deeper knowledge what is under the mask of
our car. I hope our project split which is ongoing help us to be better in
terms of documentation, usability and decrease those problems or even
eliminate it.

Feel free ask any specific questions once you start building something
maybe we will be able to help you enough fast to get your job forward.

Piotr
