This should be a low priority. We never got much adoption of that stuff in Seam.

Yes, the only way to really make this work properly is to fix it at
the container level.

We can probably support the same thing as Seam2, i.e. managed beans in
a special deployment location loaded on Weld's own classloader.
Probably worth doing, since Seam users seem to like this. However, the
real fix has to happen at the container level and for that we need
buy-in from the AS6 and EJB teams. So far this has been very, very
difficult.

This is something we should try and prioritize.

Agreed. JSF2 now has some stuff for this, right? I would definitely
like to search for alternative options.

I think we should try and toss all the stuff we have in Seam2 for
loading "mini" filters and servlets. The servlet spec now has
annotations and a componentized web.xml.

This has medium priority. Probably need to properly review the design
of all that stuff.

What does this mean? Conversations?

The security stuff is one of the *most* important features of Seam,
but needs to go through a review/redesign. We need to:

* emphasize use of user-defined annotations representing permissions (CDI style)
* ditch use of EL in Java code
* deemphasize drools
* use what the servlet 6 spec now has for authentication (you can call a method)

And we should really look for functionality to "trim" from this stuff.


> 15) Pageflow (?)

This should be for backward compatibility with Seam2 only. I want to
design a typesafe Java-based solution.


> 18) Seam application framework (Dan/Jozef)

Leave this to me. I now have some different ideas that I need to try out.



> 20) Javascript remoting (Shane)

Make sure that this is a very generic solution for CDI. i.e. it's a
CDI bean remoting layer.
