Re: [flexcoders] Re: Architecting a large, modular Flex application

[Anatole Tartakovsky]

Paul,
  Could you please clarify your question - it seems that there are number of issues that are mixed up here. First, there is no issue of RSL caching in the browser unless you specifically enable some expiration scheme. 

 
I have seen people loading multiple applications side by side - using the same RSLs - that is essentially the question if you want to isolate your runtime libraries in case of versioning in the future - that would essentially hurt performance

 
Finally, there is an issue of loading RSLs in the root appDomain - essentially you do not have a chance to do reloading of the classes till the application startup. Also, there is obvious problem with versioning.

 
Seems we are done with the client - now the question is how to build RSLs so it is the smallest, most recent, and up to date one.
 
That's were it breaks in the beginning. Essentially, if you are using dynamic instantiation of any class in the RSL, the main application would not know whic objects to initialize/which dependent classes to include. One solution we are using is to build self initializing modules and use them instead of RSLs that would of been extracted out of SWCs by the build process.

 
HTH,
Anatole Tartakovsky
