Re: Leveraging the header/resource usage of A4J in MyFaces Tomahawk?

[Grant Smith <wo...@gmail.com>]

Andrew,

I'm following up to this on the Dev list, as it really belongs there. I
agree with you
regarding the ExtentionFilter issue, and I have seen criticism to the
Tomahawk
approach in the past. There is an ongoing discussion on the Dev list
considering the
direction Tomahawk (or "Tomahawk2"), so please feel free to comment.
