I'm currently migration 3.3.3->4(CR1)
It's appear these components don't exist in richfaces 4 CR1:
<rich:paint2D> (replaced by <a4j:mediaOutput> (?))
<rich:page>--->nothing ? ( sniff:-( )
Are they really removed in RF4 or they will be added in 4.0.0-Final?
May be if these components are removed they can be added in the Migration_Guide.pdf
except page all are mentioned there.
Yup rich:page not ready and will be reviewed after final. Actually it wasn't too popular as most of the develoeprs used just plain Y! based html to create templates. That's why was prioritized in that way.
